The map is printed by the printer 22. At the same time, the printer 22 displays a numerical value representing the longitude and latitude of the world geodetic system or the Japanese geodetic system at least on the diagonal of the map image, for example, the upper left corner and the lower right corner (or the upper right corner and the lower left corner). In the example, a machine-readable code image such as QR code (product name) is printed in the vicinity of the map image.

  The user who investigates using the survey form enters the contents and state of the building damage on the survey form, and selects any of the X × Y (38 × 53 = 2014 in the embodiment) meshes of the map form. For example, a red mark indicating the building damage occurrence location is entered by handwriting, for example.

  After that, the map sheet on which the above marking is performed and the completed survey form are collectively read by the scanner 24. By reading a code image such as a QR code, the diagonal coordinates (longitude and latitude) of the map image represented by the code image are recognized. At the same time, the color pixel recognition technology is used to determine which mesh of the 2014 red mark is present, and the longitude and latitude of the mark location are obtained by a predetermined calculation formula.

  In this way, it is possible to correctly confirm on the map the disaster location investigated with the survey form.

  Referring to FIG. 2, each area of program area 26, data storage area 28, and flag area 30 is set in internal memory 18 shown in FIG. In the program area 26, for example, the above-described map operation program 261, print program 262, and reading program 263 are set in addition to an OS program 260 such as Windows (product name). However, the printing program 262 and the reading program 263 may use the components of the map operation program 261 as they are in a necessary scene. The data storage area 28 stores necessary data until the execution of each of the programs 260-263. Similarly, the flag area 30 stores a flag as necessary during the execution of each program.

  The print program 262 reads the map data stored in the map database 20 according to the flowchart shown in FIG. 3, displays the map data on the monitor 16 as a map image, and processes or manipulates the displayed map image. This is a program for printing the result by the printer 22. The map image operation or processing includes, for example, enlargement / reduction operation, drag movement operation, printer setting operation, print frame setting operation, and QR code designation operation.

  The reading program 263 is an application for reading a map in which a mark is written as described later and specifying the mark position as geodetic system data.

  When the print program 262 is executed, a map operation GUI 32 as shown in FIG. 4 is displayed on the monitor 16 in the first step S1 of FIG. The map operation GUI 32 includes an operation setting area 34 and a map display area 36. The map display area 36 is an area for the computer 12 to display a map image according to the map image data read from the map database 20. The operation setting area 34 is an area for displaying operation buttons and the like for the user to operate map data and a printer while viewing the map image, and to perform printer settings, print frame settings, and the like.

  At the end of the map printing operation, data of the map database 20 indicating the map image at that time, for example, data indicating the use layer number (name), display location, etc. is stored in the data storage area 28 shown in FIG. 2 as default values. Is done. In step S1, data is read from the map database 20 on the basis of the stored data. In step S1, the map image at the end of the previous printing is displayed at the display position at that time. Therefore, for example, the same map printing operation once interrupted can be easily resumed.

  When the map image is displayed in step S1, the latitude and longitude data of the reference point is simultaneously read from the map database 20 with the specific position on the map image, for example, the upper left corner as the reference point, and the data stored in the memory 18 is stored. Stored in area 28. The latitude / longitude data of the reference point is used to specify, for example, the diagonal longitude / latitude of the print frame when a print frame is specified later.

  However, it goes without saying that the map image displayed in the map display area 36 of the map operation GUI 32 in step S1 can be changed to an arbitrary map image by, for example, a method such as address search described later.

  Further, when the scale setting unit 38 included in the operation setting area 34 of the map operation GUI 32 is clicked with a mouse (not shown), the scale (degree) of the map image data used at that time can be set. For example, an arbitrary scale (degree) can be set by clicking a scale setting unit 38 and then inputting an appropriate numerical value using a keyboard (not shown). In the embodiment, as a scale that can be set, a scale from 1/425 to 1/1648 can be freely set.

  The slider 40 included in the operation setting area 34 is used to change or set the scale of the map image displayed in the map display area 36, and when the user changes the scale of the map image, the operation device 14. The slider 40 is displaced left or right with a mouse (not shown) shown in FIG.

  When the slider 40 is operated, “YES” is determined in the step S3 in FIG. 4, and a process for enlarging or reducing the display range is executed in a subsequent step S5. This enlargement / reduction process enlarges or reduces the display range of the map image displayed in the map display area 36, and changes the map scale itself set as the state by the scale setting unit 38. Not prescribed.

  Specifically, in the first step S31 shown in FIG. 5, the computer 12 determines whether the slider 40 has been moved to the right by detecting an input from a mouse (not shown) included in the operation device 14. . If “YES” is determined, the computer 12 subsequently recalculates the scale of the display map image that increases in accordance with the amount of rightward movement of the slider 40 in step S33. If “NO” is determined, the computer 12 recalculates the scale of the display map image that becomes smaller in accordance with the left movement amount of the slider 40 in step S35. That is, when the slider 40 is moved to the right, the range of the map image displayed in the map display area 36 is narrowed (reduced), which means that the scale of the displayed map image is increased. When moved to the left, the range of the map image displayed in the map display area 36 is widened (enlarged), and therefore the scale of the displayed map image is reduced.

  When the recalculation of the scale of the display map image is completed, in the subsequent step S37, the map image is enlarged or reduced equally in the vertical and horizontal directions with the center point of the map display area 36 as a reference point, and the map image is redisplayed.

  However, if the scale setting unit 38 changes the map scale itself, the range of the map image displayed in the map display area 36 is also enlarged or reduced in real time accordingly.

  If “NO” is determined in the step S3 in FIG. 3, the computer 12 determines whether the user's operation is a drag movement in the next step S7. The hand icon 42 displayed in the operation setting area 34 is an operation means for dragging and scrolling the map image displayed in the map display area 36, and an arbitrary place on the displayed map image is displayed. You can drag. In step S7, it is determined whether or not the hand icon 42 has been operated.

  In the drag operation, when the entire map display area 36 is scrolled up and down, left and right, when the mouse is moved to an arbitrary point of the displayed map image and the mouse is moved, the map image displayed in the map display area 36 is also displayed. Scroll in the moving direction. Then, the user confirms the map image of the map display area 36 whose display range is changed as a result of scrolling, and when the user reaches the desired movement location, the user cancels (drops) the left-clicked state, thereby scrolling. Stop.

  Note that the scrolling of the map image by dragging and dropping is convenient because it can be easily performed when the scroll direction is changed in the diagonal direction or in the reverse direction, but in the sense that the same can be done as a result, the drag movement is This is the same as vertical and horizontal scrolling, and therefore vertical and horizontal scrolling may be employed instead of drag movement.

  The drag movement process is executed in accordance with step S9, specifically, FIG. In the first step S41 of FIG. 6, the computer 12 determines whether or not the scroll start point of the map display area 36 is designated by the mouse. That is, it is determined whether or not the user left-clicks the mouse at an arbitrary point in the map display area 36 in accordance with the input from the operation device 14. If “NO”, wait for the start point to be specified. If “YES” is determined, the computer 12 determines whether a drag operation, that is, a move operation using the mouse, has been performed based on the input from the operation device 14 in the subsequent step S43. If “NO” is determined in the step S43, a drag operation, that is, a mouse movement is awaited. If “YES” in the step S43, the computer 12 scrolls the map image in a step S45 according to the moving direction and the moving amount of the mouse.

  In the next step S47, it is determined whether or not the drag operation is stopped. If “NO”, in step S49, the computer 12 further determines whether it has reached one of the top, bottom, left and right ends of the map display area 36 by drag movement. to decide. The computer 12 makes this determination by comparing the coordinates of the momentary movement of the mouse with the coordinates of the upper, lower, left and right edges of the map display area 36. If "YES" is determined in the step S49, the computer 12 releases (drops) the map image and stops scrolling in the next step S51. That is, when the drag exceeds the map display area 36, the drag is forcibly stopped (dropped), and the process returns to step S43.

  As a result of scrolling, when the display of the map image reaches the desired moving location, the user releases the left-clicked state and stops the drag operation. If it is determined in step S47 that the drag operation has stopped and “YES” is determined, the computer 12 drops the map image and stops scrolling in step S53, as in step S51. In this scroll operation, the map image changes every moment, and the longitude and latitude of the reference point (upper left corner) also change every moment, but the longitude and latitude data of the reference point of the finally dropped map image is stored in the data storage area 28. become.

  If the determination in step S7 of FIG. 3 is “NO”, it is determined in the next step S11 whether the user operation is a printer setting operation. That is, it is determined whether or not the printer setting button 44 set in the operation setting area 34 has been operated. When the printer setting button 44 is operated, the printer setting GUI 46 shown in FIG. 7 is superimposed on the map display area 36. Such a printer setting GUI 46 is already well known in, for example, Windows (registered trademark) installed as the OS 260, and sets the model of the printer to be used, the paper size, the printing direction (vertical or horizontal), and the like.

  This printer setting operation is executed in accordance with step S13, that is, the flowchart of FIG. 8, which is already well known, and will be briefly described here.

  In step S61 of FIG. 8, the computer 12 reads predetermined values such as the printer name, paper size, printing direction, and paper feeding method at that time. In the next step S <b> 63, the computer 12 determines whether or not a change is instructed to those specified values based on the input from the operation device 14. After the determination of “YES” in step S63, if the printer change instruction is confirmed in step S65, the changed printer name is registered in the next step S67. If “NO” is determined in step S65 instead of the printer change instruction, it is determined whether or not a change in the paper size is instructed. If “YES”, in the subsequent step S71, the computer 12 registers the changed paper size. If “NO” in the step S69, it is next determined whether or not a change of the printing direction is instructed in a step S73. If “NO”, the process returns as it is when “NO” is determined in step S63. If “YES”, in step S75, the changed printing direction, vertical or horizontal is registered.

  In this way, the printer for printing is selected and registered, and at the same time, the designated paper size (A4 size (210 mm × 297 mm) in the embodiment) and the printing direction (vertical or horizontal based on the scale at the time of map printing) Is changed.) Is registered. These data can also be registered in the data storage area 28 (FIG. 2). In particular, the vertical and horizontal lengths of the paper size and the scale when printing (displayed in the scale setting unit 38 in FIG. 3) are used to calculate the actual distance that can be printed (entered) in the paper. This is an important setting value. Details will be described in the following “print frame designation”.

  If “NO” is determined in the step S11 of FIG. 3, then in step S15, the computer 12 determines whether or not the user's operation at that time is “print frame designation”. By operating a print frame designation button 48 set in the operation setting area 34, a print frame indicating an area to be printed on the map image displayed in the map display area 36 can be set. Accordingly, in step S15, it is determined whether or not the user operation is a print frame designation operation depending on whether or not the print frame designation button 48 has been operated. The print frame is a print target on the map image based on the paper size and print direction specified by the printer setting operation (FIG. 8) and the scale set by the scale setting unit 38 (FIG. 4). It means such a “frame” that displays an area using a frame. In a printing operation described later, printing and preview are performed in units of frames.

  As shown in FIG. 9 or FIG. 10, the print frame 52 is a frame indicating a print area for one sheet of the sheet size set by the printer setting operation, and a reference point 54 at the upper left corner of the map display area 36 is displayed. As a reference, it is displayed superimposed on the map image. Although only one print frame is shown in FIG. 9, in the print frame setting operation, the number of sheets on which the area on the map image to be printed is printed can be set as a numerical value (vertical number and horizontal number). Such a number setting can be increased or decreased by operating the up arrow or the down arrow in the number setting window 50. When the printing of a plurality of sheets is set, as shown in FIG. 10, a plurality of printing frames 52 (6 in the embodiment, 2 in the vertical direction and 3 in the horizontal direction in total) are displayed. Each data registered by the printing frame designation described in detail below is also stored in the data storage area 28 (FIG. 2) of the memory 18.

  In the first step S81 in FIG. 11, the computer 12 refers to the data storage area 28 of the internal memory 18 and determines whether data relating to the print frame has already been registered. In the case of “YES”, it will be described later, but in the case of “NO”, in the next step S83, the computer 12 causes the position data of the reference point 54 in the upper left corner of the map display area 36, that is, longitude and latitude (NX, NY). To get. In the case of this embodiment, the position data (NX, NY) is obtained by using one component (function) of the program 261 when the map data is read from the map database 20 by the map operation program 261 in the aforementioned step S1. Obtained from the map database 20 and already stored in the data storage area 28. That is, the map database 20 has not only the layer of the map image data but also a longitude / latitude layer that holds the longitude / latitude data of each position of the map image. As described above, the map image data is read out in step S1. At this time, the longitude and latitude data of the reference point (upper left corner in the embodiment) of the map image is also read out.

In the subsequent step S85, the computer 12 calculates the actual distance on the map that enters one print frame 52 in accordance with the following equation (1). Therefore, this step S85 constitutes an actual distance calculation means, that is, a first distance calculation means.
[Equation 1]
Horizontal distance = (PX-US) x SS
Vertical distance = (PY-LS) x SS
However, the paper size is (horizontal: PXmm vertical: PYmm), the total margin at the top and bottom of the sheet is USmm, the total left and right margin is LSmm, and the scale is SS.

For example, when the paper size is 210 mm in width and 297 mm in height (A4), the upper and lower margin total US is 30 mm, the left and right margin total LS is 20 mm, and the scale is 1,000 (1 / 1,000). Then, the horizontal distance is (0.21-0.02) × 1000 = 190 meters, and the vertical distance is (0.297−0.03) × 1000 = 267 meters.

  Thereafter, in step S87, the computer 12 determines whether the number of prints is one. When “vertical 1” is set and “horizontal 1” is set in the number setting section 50 shown in FIG. 4, “YES” is determined in this step S87. When a numerical value of 2 or more is set in at least one of “vertical” and “horizontal” in the number setting section 50, “NO” is determined in the step S87.

  When “YES” is determined in the step S87, in the subsequent step S89, the computer 12 determines a rectangular printing frame on the internal coordinates for printing one sheet, and uses the printing frame 52 and the page number in the user layer. draw. However, this print frame and page number are executed by using the function of the component of the map operation program 261.

  Specifically, by converting the internal coordinates (longitude and latitude) of the map image from the actual vertical and horizontal distances of the map image printed on one sheet calculated in step S85 as described above, The distance on the internal coordinates, the horizontal AX, and the vertical AY of one printing frame 52 can be calculated. Accordingly, when only one print frame 52 is set as shown in FIG. 9, the left coordinate and right coordinate of the print frame 52 in FIG. 9 are used in step S89 by using the position (NX, NY) of the reference point 54. The upper and lower coordinates are calculated as “NX”, “NX + AX”, “NY”, and “NY + AY”, respectively, and the print frame 52 is drawn accordingly. Accordingly, when one print frame is set, step S89 functions as diagonal longitude and latitude calculation means, and further constitutes a premise of internal coordinate distance calculation means, that is, second distance calculation means.

  FIG. 10 illustrates a case where printing is performed using a total of six sheets of 2 sheets in the vertical direction and 3 sheets in the horizontal direction. However, when setting a plurality of print frames 52 in this way, the computer 12 determines in step S91. Based on the left coordinate “NX” and the upper coordinate “NY” and the internal coordinate distances “AX” and “AY” for one sheet, the vertical and horizontal coordinates in the geodetic system of each square are obtained. For example, the rectangular geodetic system position data indicated by the page number “1” in FIG. 10 is given as “NX” for the left coordinate, “NY” for the upper coordinate, “NX + AX” for the right coordinate, and “NY + AY” for the lower coordinate. .

  Similarly, in the rectangular geodetic system position data indicated by the page number “2”, the left coordinate is “NX + AX”, the upper coordinate is “NY”, the right coordinate is “NX + 2 × AX”, and the lower coordinate is “NY + AY”. .

  In the rectangular geodetic system position data indicated by the page number “3”, the left coordinate is “NX + 2 × AX”, the upper coordinate is “NY”, the right coordinate is “NX + 3 × AX”, and the lower coordinate is “NY + AY”.

  In the rectangular geodetic system position data indicated by the page number “4”, the left coordinate is “NX”, the upper coordinate is “NY + AY”, the right coordinate is “NX + AX”, and the lower coordinate is “NY + 2 × AY”.

  In the rectangular geodetic system position data indicated by the page number “5”, the left coordinate is “NX + AX”, the upper coordinate is “NY + AY”, the right coordinate is “NX + 2 × AX”, and the lower coordinate is “NY + 2 × AY”.

  In the rectangular geodetic system position data indicated by the page number “6”, the left coordinate is “NX + 2 × AX”, the upper coordinate is “NY + AY”, the right coordinate is “NX + 3 × AX”, and the lower coordinate is “NY + 2 × AY”. .

  In this way, when printing on a plurality of sheets, in step S91, each rectangle is determined based on the left coordinate “NX”, the upper coordinate “NY”, and the internal coordinate distance “AX”, “AY” for one sheet. The geodetic system position data of the upper, lower, left and right coordinates is determined, and each print frame and page number are drawn on the user layer accordingly. Therefore, when a plurality of print frames are designated, step S91 functions as a diagonal longitude and latitude calculation unit of each print frame, and further, as an internal coordinate distance calculation unit, that is, a second distance calculation unit as a premise thereof. Function.

  As described above, in the calculation means for calculating the longitude and latitude of the diagonal position of the print frame, the reference point or the reference position corresponds to one of the diagonals of one print frame. By adding the above distance, the other longitude and latitude of the diagonal can be calculated. However, when there are a plurality of print frames, as already described, one of the diagonals of each print frame other than the first print frame is also calculated by adding the longitude and latitude of the reference position and the distance on the internal coordinates. There is a need.

  Then, when the user instructs registration, for example, when the user clicks the print setting save button 58 shown in FIG. 4, the computer 12 determines “YES” in step S93, and in the subsequent step S95, for example, the print frame is the user. As graphic data in the layer, the page number is registered in the data storage area 28 together with each coordinate data (position data) as text data in the user layer.

  If the registered data is used in step S81, the printing frame and page number are drawn as shown in FIG. 9 or FIG. 10 in accordance with the registered data in step S97. As described above, since the registered data can be used, a map in which the same map image is printed under the same conditions can be easily obtained, for example, when the printing operation once interrupted is resumed.

  In the print frame designation process, the print frame can be moved by operating the move button 53 (FIGS. 9 and 10) regardless of whether the print frame is single or plural. This print frame movement process uses one of the functions of the map operation program 261. When the user clicks this print frame movement button 53, the figure movement mode is set, and although not shown, a cross cursor is displayed on the screen. When the user appears and uses it to determine the destination and click, the print frame moves to that position. In this case, the print frame designation process in FIG. 11 is executed with the upper left corner of the moved print frame as the reference point (NX, NY). At this time, the upper left corner of the print frame will deviate from the reference point (upper left corner) on the map image. At that time, the longitude and latitude of the upper left corner of the print frame and the latitude and longitude of the reference point (upper left corner) of the map image It is necessary to calculate the displacement distance and direction from the reference point, and to calculate the point displaced from the reference point in the displacement direction as the longitude and latitude of the upper left corner of the print frame. That is, when an operation for shifting the print frame from the reference point is performed, it is necessary to recalculate the longitude and latitude of the upper left corner (in the embodiment) of the print frame in accordance with the shift.

  When “NO” is determined in step S15 of FIG. 3, the computer 12 determines whether or not the user operation is a QR code setting operation in step S19. If “YES”, then the process proceeds to a QR code designation process in step S21. One feature of this embodiment is that the coordinate data of the geodetic system acquired as described above is printed simultaneously with the map image by the QR code, and is used for specifying the position on the map.

  When the user clicks the QR code setting button 60 in FIG. 4, the computer 12 correspondingly temporarily displays the QR code setting GUI 62 shown in FIG. 12 on the map operation GUI 32 in FIG. 4, for example.

The QR code setting GUI 62 includes a color specifying unit 64 that sets the color of the QR code, a geodetic system specifying unit 66 that sets the geodetic system, and a numerical value format specifying unit 68 that sets the numerical format. The color designation unit 64 can designate one of four colors of blue, red, green, and black. The geodetic system designating unit 66 can designate either the Japanese geodetic system or the world geodetic system. Since the coordinate system that can be handled may differ depending on the GIS application program that displays the result, either one can be specified. The numerical value format designation unit 68 can designate either the degree / minute / second format or the degree format. As an example, geodetic coordinate data expressed as “135403964” (135 degrees 40 minutes 39 seconds 64 east longitude) in the degree minute second format is “135804824” (135.804 east longitude) in the degree format.
824 degrees).

  In the QR code setting process shown in detail in FIG. 13, first, in steps S101 and S103, the computer 12 registers the color of the QR code to be printed at the same time as the map according to the user's operation, and in steps S105 and S107, the geodetic system is set. A world geodetic system or a Japanese geodetic system is registered, and in step S109 and S111, a numerical format of either a degree minute second format or a degree format is registered. Data of this QR code setting process can also be registered in the data storage area 28.

  A preview button 70 shown in FIG. 4 is an operation button for executing a print preview. When the user operates the preview button 70, the print preview is executed. However, the print preview is performed in units of print frames set in accordance with step S17, that is, the operation flow of FIG.

  By operating the print button 72 set in the operation setting area 34 in FIG. 4, the map display area 36 is printed for each print frame according to the conditions set in the printer setting operation and the print frame setting operation in step S <b> 23 in FIG. 3. The map image displayed on is printed on the paper 74 (FIG. 15). Specifically, this printing process is executed according to the flowchart shown in detail in FIG. However, it should be pointed out in advance that the specific numerical values referred to in the respective steps of the flowchart of FIG. 14 are merely examples and are not restricted by these numerical values.

  In the first step S121, the computer 12 reads out data from the data storage area 28 (FIG. 2), and based on the left margin, top margin, and paper size data registered by the print setting operation, the vertical and horizontal directions of the map image are displayed. Determine the print length.

  Subsequently, in step S123, the computer 12 uses the QR code setting operation to set the upper left longitude, upper left latitude, lower right longitude, and lower right latitude of each print frame 52 calculated by the print frame designation operation described above. Convert to numeric data according to system and degree / minute / second format. However, as described above, it is only necessary to have longitude and latitude data of at least the diagonal (upper left corner and lower right corner) of the print frame 52. Conversely, the lower left longitude, lower left latitude, upper right longitude of the print frame 52, Numerical data of the upper right latitude may be used. This numerical data is temporarily stored in the data storage area 28.

  In the next step S125, the computer 12 generates a map image having a printing length of 265 mm in length and 200 mm in width with the upper left corner of 10 mm from the left and 11 mm from the top of the paper 74 shown in FIG. That is, in this embodiment, the printing length of 265 mm long × 200 mm wide is determined in step S121.

  In the subsequent step S127, the computer 12 generates a QR code image in an area in which margins of 10 mm from the left of the paper 74 and 275 mm and 2 mm from the top are opened. The QR code image at this time is obtained by encoding the data of the upper left longitude, the upper left latitude, the lower right longitude, and the lower right latitude previously converted in step S123. For example, numerical values such as “1355051019, 347056606, 1355098019, 347006450” in the degree format are encoded (imaged) with a QR code.

However, in this embodiment, in order to create a QR code image, for example, http: //www.v
Freeware that can be obtained at ector.co.jp/soft/win95/writing/se359398.html was used.

  In steps S129 and S131, the computer 12 generates a fine line image for mesh. In the embodiment, the mesh is printed on the map image 76 as a mark for the user to add a mark later, and the number is vertical and horizontal (Wx, Wy). In step S129, the number of vertical thin line images capable of forming Wx meshes is generated, and in step S131, the number of horizontal thin line images capable of forming Wy meshes is generated. The number of meshes (Wx, Wy) is set in a predetermined register in the data storage area 28 of the memory 18. In this embodiment, as an example, in step S129, 39 vertical thin line images are generated at intervals of 5 mm from the left 10 mm of the paper 74 from the position of 11 mm from the top to the position of 276 mm. In step S131, 54 horizontal thin line images with an interval of 5 mm from the top 11 mm are generated from the position 10 mm from the left to the position 200 mm to the right. Accordingly, in this embodiment, a total of 2014 (= 38 × 53) meshes are formed on the map image.

  These generated images are temporarily stored in the data storage area 28 as bitmap print data, for example, and are printed on the paper 74 as shown in FIG. 15 in the next printing step executed in step S133.

  However, in this embodiment, with respect to the above printing process and preview process, in addition to the map operation program, the preview control and printer setting component in Delphi's freeware (http://mrxray.on.coocan.jp/) is used. , While modifying some source code.

  Referring to FIG. 15, a map image 76 is printed on a sheet 74 with the vertical and horizontal print lengths exemplified above, and a QR code 78 is placed at a position exemplified above below the map image 76. Code setting operation data Printed in the set color. The map image 76 may be a monochrome image shown in FIG. 15 or a color image. However, in the case of a color image, in order to ensure the identification of the mark, it is desirable that the color is printed in a single color that can be clearly distinguished from the color of the mark 102 to be entered later by the user.

  FIG. 15 shows a large number of fine lines printed at regular intervals in the vertical and horizontal directions superimposed on the map image 76, and a large number (in the embodiment, 2014) of meshes 80 are formed by these vertical and horizontal thin lines. It is formed. These meshes 80 perform a function of specifying a position when a mark is written in this map. That is, by writing a mark on any of these meshes, the location where the mark is written is specified by the longitude and latitude values in the execution of the reading program described later.

  In the embodiment shown in FIG. 15, a map number 81 is printed on the right side of the QR code 78 below the map image 76, and an ID entry field 82 for entering the survey ID is printed on the right. . The map number 81 is a number for individually identifying the map image, and can be arbitrarily set by the user. In particular, when the QR code cannot be read, the map number may be printed as information for determining the map cutout position. In addition, since the map of this embodiment is assumed to be used for the damage investigation, an ID set in advance in the investigation form (not shown) is entered in the entry column 82. For example, when the map and the survey form are printed on different sheets, it is assumed that the content of the QR code printed on the survey form (not shown) is written by hand.

  In the embodiment described above, a setting method for displaying a map image in the map display area 36 of the map operation GUI 32 according to the map image data read from the map database 20 and setting a print frame with the upper left corner as a reference point 54. Explained. However, in this embodiment, since desired map data can be searched based on the address notation, the address searching method will be described next.

  When performing an address search, although not shown, for example, the print frame designation process (steps S15 and S17) of FIG. 3 may be changed to an address search process.

  For example, by operating the address search / large letter frame button 84 set in the operation setting area 34 of the map operation GUI 32 in FIG. 4, the user selects setting of a print frame by address search, that is, a large letter (blue) frame. it can. Therefore, for example, in step S15, the computer 12 detects whether or not the user has operated the button 84, and in response to detecting the operation of the button 84, “YES” is determined in step S15, as shown in FIG. The address search GUI 86 may be displayed and a print frame setting process by address search may be executed in step S17.

  When the user operates the address search / larger frame button 84 to select a print frame setting operation for address search, the address is superimposed on the map display area 36 of the map operation GUI 32 as shown in FIG. A search GUI 86 is displayed. The address search GUI 86 is a component included in the map operation program 261, and is used here as it is. The address search GUI 86 includes a prefecture column 88 for selecting or specifying a prefecture, and a city column 90 for selecting or specifying a city. In the large character field 92 for designating a large character (Ozama) and the character character column 94 for designating a character (character chome), a large character and a character chome that can be selected in the municipality displayed in the municipality field 90 are displayed. Are displayed in the form of a pull-down menu, the user designates them arbitrarily.

  In the first step S141 in FIG. 17, the computer 12 stores map data in the map database 20, and therefore extracts data of selectable prefecture names from the map database 20. In subsequent step S143, the prefecture name is displayed in a list in the prefecture column 88. That is, a list of prefecture names of map data available at that time is acquired and displayed. In this embodiment, the map operation program 261 can be used to acquire the map image data from the map database 20 including the attribute data.

  However, when the map data in the map database 20 is only one prefecture, the corresponding prefecture is automatically displayed in the prefecture column 78.

  Then, the user selects or designates the desired prefecture by clicking on the name of the prefecture from the list of prefectures, but the computer 12 detects in step S145 that the user has selected the prefecture, and thereafter, step S147 and Execute S149 to extract selectable city names whose map data is stored in the map database 20 and list them in the city column 90. However, when the map data in the map database 20 is only one municipality, the corresponding municipality is automatically displayed in the municipality column 90.

  The user selects or designates a city by clicking a desired city name from the list of cities. This is detected in step S151. Therefore, the computer 12 executes the subsequent steps S153 and S155, extracts the large name of the designated city, and displays it in the large character column 92 as a list.

  When one large letter is designated by the user, this is detected in step S157. In the subsequent step S 159, the computer 12 extracts a character block for the designated large character, searches for a block and a lot number, and displays it in the character block field 84.

  When the user designates a desired large letter as described above, the computer 12 selects the address polygon (map image data) corresponding to the large letter and the longitude and latitude data of the reference point (for example, each vertex) of the address polygon in step S161. Are extracted from the map database 20 and the address polygon 96 shown in FIG. 18 is displayed in the map display area 36 in step S163, and the longitude and latitude data of the reference point of the address polygon is stored in the data storage area 28.

  For example, when a user single-clicks a mouse (not shown) at a selected position of the large character list in the large character column 92, in response to the single click, the computer 12 obtains a corresponding character chome list from the map database 20 and reads the character. When the user double-clicks the mouse at a selected position of the large character list in the large character column 92, the computer 12 responds to the double click and the computer 12 displays graphic information (map polygon) of the corresponding large character part. 96 is obtained from the map database. The map display is moved to the map polygon portion, and the color display of the map polygon 96 is changed to blue, for example.

  Note that the map database 20 includes administrative boundary polygon data composed of address polygons of prefectures, municipalities, large letters, and alphabets. Each address polygon is constituted by data such as vertex information indicating the shape of the polygon, an administrative name indicating the name of the address, and representative coordinates. For example, the map polygon 96 shown in FIG. 18 includes vertex information indicating the shape of the map polygon 96, an administrative name indicating the name of the capital letter, representative coordinates of a position representing the map polygon 96, and the like. Therefore, in step S161, the longitude and latitude data of the reference point of the map polygon 96, that is, each vertex information can be extracted from the map database 20.

  Thereafter, in step S145, a display process for a large print frame is executed. More specifically, the large print frame display process is executed according to the flowcharts shown in FIGS.

  In the first step S171 in FIG. 19, the computer 12 obtains a list of vertex information (X, Y) groups of the polygon 96 shown in FIG. 21 from the large polygon 96 in FIG. However, this vertex information is read out simultaneously with reading out the address polygon as described above by the function of the map operation program 261 and stored in the memory 18. Then, the computer 12 determines the coordinates of each corner of the quadrangle 98 as the print frame shown in FIG. 22 based on the vertex information. Since the quadrangle 98 needs to include the large polygon 96, the square is circumscribed by the large polygon 96. As shown in FIG. 22, the left coordinate of the quadrangle 98 is the minimum value of the X axis of the vertex information group. (LX), the right coordinate is the X-axis maximum value (RX) of the vertex information group, the upper coordinate is given by the Y-axis minimum value (LY) of the vertex information group, and the lower coordinate is the Y-axis maximum value of the vertex information group (RY).

X-axis minimum value of vertex information group = left coordinate of a rectangle (LX)
X-axis maximum value of vertex information group = Right coordinate of rectangle (RX)
Y-axis minimum value of vertex information group = quadrature upper coordinate (LY)
Maximum Y-axis value of vertex information group = bottom coordinate of rectangle (RX)
Thereafter, the vertical distance AY and the horizontal distance AX in the internal coordinates of the quadrangle 98 are set in step S173 in the paper size and scale setting unit specified in the printer setting operation in the same manner as in step S85 of FIG. Calculation is performed based on the scale and the data is stored in the data storage area 28.

In step S175, the computer 12 assumes a quadrangle 98 as a base of the print frame shown in FIG. 22, and sets the distance of the X axis of the quadrangle 98 as W and the distance of the Y axis as H according to Equation 2.
[Equation 2]
W = RX-LX
H = RY-LY
In step S177, the computer 12 performs an integer operation to calculate the number of frames NeedX required in the horizontal direction. That is, the lateral distance W of the quadrangle 98 calculated in step S175 is divided by the lateral distance AX calculated in step S173 (step S177). In step S179, it is determined whether or not there is a surplus W mod AX. In some cases, the quotient of the integer operation is directly registered as the necessary number of horizontal frames NeedX. If “YES” is determined in the step S179, the necessary frame number NeedX is registered as NeedX + 1 in a step S181.

  In step S183, the computer 12 performs the same integer calculation to calculate the frame number NeedY required in the vertical direction. That is, in step S183, the vertical distance H of the quadrangle 98 is divided by the vertical distance AY, and in step S185, it is determined whether or not there is a remainder H mod AY. Registered as the required direction frame number NeedY. If “YES”, in step S187, the required frame number NeedY is registered as NeedY + 1.

  However, most of the experiments existed in the inventors' experiments.

  In this way, the necessary frame numbers NeedX and NeedY of the print frame can be calculated. In the subsequent step S189, the computer 12 calculates the length of the margin. With the same idea as “centering” in text editing, the margins in each print frame are adjusted so that the selected large letter is positioned exactly in the middle. In other words, the “margin” here means a difference from the actual printing frame 100 that can be arranged around the circumscribed rectangle 98 of the large polygon 96 as shown in FIG.

First, the length of the margin can be calculated from the required number of sheets NeedX and NeedY by the method shown in the following Expression 3.
[Equation 3]
Distance on the internal coordinates of the margin in the X-axis direction (YohaX) = (LX + (AX * NeedX))-RX
Y-axis margin in internal coordinates (YohaY) = (LY + (AY * NeedY))-RY
The X-axis margin YohaX is a margin when a printing frame having the number of frames NeedX, each having the X-axis length AX, is arranged between the X-axis minimum coordinate LX and the maximum coordinate RX of the quadrangle 98. The Y-axis margin YohaY is a margin when a printing frame having the number of frames NeedY, each having a Y-axis length AY, is arranged between the Y-axis minimum coordinate LY and the maximum coordinate RY of the quadrangle 98.

If the lengths of the margins YohaX and YohaY are halved and the reference point is shifted in the minus direction (upper left direction in FIG. 24), the selected large character 96 can be arranged at the center of the printing frame 100. The new reference point after the margin adjustment can be calculated as shown in Equation 4. [Equation 4]
New reference point X coordinate (NX) = LX- (YohaX / 2)
New reference point Y coordinate (NY) = LY- (YohaY / 2)
After calculating the new reference point coordinates (NX, NY) in this way, in step S193, an image of the print frame 100 shown in FIG. 25 is generated and drawn (displayed) on the user layer. By setting this print frame 100, the large-size map selected by the user is centered as a whole in the print frame 100, and can be printed in each print frame as shown in FIG.

  As shown in FIG. 15, the user performs handwriting marking on any one of, for example, 2014 meshes 80 that are superimposed and printed on a map image 76 printed on a sheet 74. That is, the user gives a handwritten mark (in a color different from the map printing color, such as a red pen) to position information (latitude and longitude) to be recognized with respect to the printed map.

  Then, by the reading process described below, the coordinates according to the marking and the coordinates of the paper map indicated by the QR code are converted in accordance with the geodetic system, and the longitude and latitude of the position (coordinates) to which the mark is given is calculated. calculate. That is, a map with a mark such as red is read by an image reader with respect to the map printed by the previous map printing process, and the QR code and the position of the mark written on the map are detected. Based on the longitude and latitude coordinates of the upper left and lower right coordinates of the map embedded in the QR code, the position of the mesh 80 with the mark (FIG. 15) is converted to the longitude and latitude used as GIS data, and the conversion result Are output to the outside as data in CSV format or the like.

  Therefore, when reading a map, that is, a sheet, a mark reading position can be converted into longitude and latitude even if the reading computer does not have map data such as a GIS database. In other words, the system of this embodiment has an advantage that it is not necessary to set the database in a terminal such as each computer, in contrast to the conventional system that inputs map data based on the GIS database.

  Moreover, the converted coordinate data can be converted into a text file such as CSV format or general-purpose commercial data. Further, since the GIS database is not required for use, the converted GIS data is available on the Internet. A network type map system that can be used can also be constructed.

  The basic operation of the reading process is shown in the flow chart of FIG. 26. For this reading process, first, as shown in FIG. 27, the user loads the paper 74 on which the map image 76 and the QR code 78 are printed on the scanner 24 (FIG. Set to the reading position of 1). It is assumed that a mark 102 such as red is written in any one mesh in the map image.

  In the first step S201 in FIG. 26, the reading GUI 104 shown in FIG. 28 is displayed on the monitor 16 (FIG. 1). The reading GUI 104 includes an acquisition button 106 displayed in the middle of the right side. The take-in button 106 is a button for activating the scanner 24 and starting scanning of the paper 74 set at the reading position. The left half of the reading GUI 104 is an image display area 108. This image display area 108 is an area for directly displaying an image read by the scanner 24 (such as a map image or QR code on the paper 74).

  A QR code data display area 110 is provided on the upper right side of the reading GUI 104. In the QR code data display area 110, the latitude and longitude of the upper left corner of the map embedded in the QR code by two upper and lower display units. The numerical value of the longitude and latitude at the lower right corner of the map is displayed by the upper and lower two display units.

  Below the QR code data display area 110, a map number display unit 112 and a survey number display unit 114 are formed. The map number display unit 112 displays a unique number assigned to the currently read map. The survey number is a number assigned to the survey form by hand, and the number read by the scanner 24, that is, the computer 12 is displayed on the display unit 114.

  A coordinate position display unit 116 is formed between the survey number display unit 114 and the reading button 104 described above. The coordinate position display unit 116 displays a numerical value indicating the coordinate position of the mesh read by the scanner and provided with the mark 102 (FIG. 27) by the user with the red pen.

After setting the paper 74 on the scanner 24 and displaying such a reading GUI 104 in step S201, the computer 12 determines in step S203 whether the take-in button 106 formed on the reading GUI 104 has been operated by the user. To do. If “YES” is determined in step S 203, the scanner 24 is operated in a subsequent step S 205 to scan one sheet, and an image acquired thereby is displayed in the image display area 108 of the reading GUI 104. However, the image displayed in the image display area 108 is temporarily stored in an image buffer (not shown) set in the data storage area 28 (FIG. 2) of the memory 18 until the processing shown in FIG. Saved (step S207). The image displayed in the image display area 108 can be freely enlarged or reduced by the user operating an enlargement / reduction button (not shown).

  Subsequently, in step S209, the computer 12 executes mark position recognition processing. Specifically, the mark position recognition process is achieved by executing the flowchart shown in FIG.

  The first steps S221 and S223 in FIG. 29 are executed, and the computer 12 recognizes the mark 102 (FIG. 27) attached by the user. If it can be recognized, the process proceeds to step S225, and the computer 12 stores the mark position (Rx, Ry) shown in FIG. 30 in a mark position register (not shown) in the data storage area 28 (FIG. 2) of the memory 18. If “NO”, “Null” is written in the mark position register as the mark position.

  The mark position represents the position of the mesh superimposed and printed on the map image, and is not a coordinate position of longitude and latitude. Then, the upper left mesh is (1, 1), and a numerical value indicating the number of vertical and horizontal meshes is stored as the mark position (Rx, Ry).

  Returning to step S211 of FIG. 26, the computer 12 executes a QR code recognition process shown in detail in FIG.

  The computer 12 recognizes the QR code 78 (FIG. 27) by executing the first steps S231 and S233 of FIG. If it can be recognized, the process proceeds to step S235, and the computer 12 stores the longitude and latitude corresponding to the geodetic system, that is, the upper left coordinates (Ax, Ay) and lower right coordinates (Bx, By) shown in FIG. It is stored in a longitude / latitude coordinate register (not shown) in the area 28 (FIG. 2). In the case of “NO”, “Null” is written as the longitude / latitude coordinate in the longitude / latitude coordinate register.

  In step S213 following FIG. 26, the computer 12 determines whether or not there is an error in both steps S209 and S211, that is, whether or not “Null” has been written to any register in the two steps S209 and S211. To do. If it is determined that there is no error, coordinate conversion processing is executed in the next step S215. Specifically, the coordinate conversion process is achieved by the flowchart shown in FIG.

In the first step S241 in FIG. 32, the computer 12 uses the upper left coordinates (Ax, Ay) and lower right coordinates (Bx, By) shown in FIG. 30 acquired in the QR code recognition process in FIG. Read from the register once. Subsequently, in step S243 functioning as a mesh position acquisition unit, the mark position (Rx, Ry) of FIG. 30 acquired by the mark position recognition process of FIG.
) Is read from the mark position register in the data storage area 28.

In step S 245, the computer 12 reads out the vertical and horizontal numbers (Wz, Wy) of the mesh printed on the map image 76 from a predetermined register in the data storage area 28. Subsequently, in step S247, the X coordinate of the mesh marked by the user is calculated by the following equation according to Equation 5, and in the next step S249, the Y coordinate of the mesh at the mark position is calculated by the following equation. By subtracting the upper left X coordinate Ax from the X coordinate Bx, the X direction length of the entire map image can be calculated, and the X direction length is divided by the number of meshes Wx in the X direction ((Bx-Ax) ÷ (Wx )), The X-direction length of one mesh can be calculated, and by multiplying it by the mark position Rx, the numerical value of the geodetic system in the X direction of the mesh at that mark position, that is, the longitude can be obtained. By adding the longitude to the upper left coordinate Ax, it becomes the longitude of the marked mesh.

By subtracting the upper left Y coordinate Ay from the lower right Y coordinate By, the length of the entire map image in the Y direction can be calculated and divided by the number of meshes Wy in the Y direction ((By-Ay) ÷ (Wy)) Thus, the Y-direction length of one mesh can be calculated, and when this is multiplied by the mark position Ry, the numerical value of the geodetic system in the Y-direction of the mesh at that mark position, that is, the latitude is obtained. By adding the latitude to the upper left coordinate Ay, the latitude of the marked mesh is obtained.
[Equation 5]
X coordinate = Ax + ((Bx-Ax) ÷ (Wx)) x Rx
Y coordinate = Ay + ((By-Ay) ÷ (Wy)) x (Wy-Ry)
In this manner, in step S249, (X, Y) that is the longitude and latitude corresponding to the GIS data is determined.

  However, when “NO” is determined in step S223 in FIG. 26, that is, when recognition of either the mark position or the QR code fails, an error value is set for the mark position and / or the QR code. When such an error value is set, the user can call a page that has been determined to be an error as a result of image recognition and perform correction input of the mark position and / or QR code.

  Note that the longitude and latitude data determined in step S215 of FIG. 26, that is, step S251 of FIG. 32, is output as a record as a CSV file.

  In this way, by reading the map paper 74 with the mark 102 written thereon by the scanner 24 as shown in FIG. 27, the mark position can be read as GIS data.

  However, since the mark 102 can be written in any one mesh in the above-described embodiment, the user can only mark one point in the map image. Therefore, in the following embodiment, an area having an area can be designated as a polygon 102a in the map image as shown in FIG. 33, for example. Thus, if an area can be designated as a polygon on a map, damage estimation can be performed by combining a polygon indicating a damaged area and a population layer (of map data) in a disaster investigation, for example. Further, the number of flooded houses can be estimated by combining a polygon indicating a flooded area and a house layer.

  The polygon 102a shown in FIG. 33 is taken out and shown in FIG. 34. In this FIG. 34, a filled mesh is illustrated, and an outer dark mesh shows an outline. However, in FIG. 34, for the sake of simplicity, the coordinates of each mesh are illustrated not as coordinates of actual longitude and latitude but as mesh numbers of 38 vertically and 53 horizontally. When the user fills in the polygon 102a, the polygon 102a has a color (for example, red) that can be clearly distinguished from the color (for example, black) on which the map image is printed, as in the case of the previous mark 102. Shall be filled.

  In the reading processing program of FIG. 35, it is possible to cope with either a case where the user designates one mesh with the mark 102 or a case where an area extending over a plurality of meshes is designated with the polygon 102a. However, it is assumed that only one of the mark 102 and the polygon 102a can be entered on one printed map. That is, it is only possible to specify one point or an area or region.

  35. For this reading process, the user first has the map image 76 with the mark 102 and the QR code 78 printed as shown in FIG. 27, or the map image 76 with the polygon 102a as shown in FIG. The paper on which the QR code 78 is printed is set at the reading position of the scanner 24 (FIG. 1).

  In steps S251 to S257, processing similar to that in steps S201 to S207 in FIG. 26 is executed, and the read image data is temporarily stored in the image buffer. After that, as in step S211, the QR code recognition process shown in detail in FIG. 31 is executed, and coordinate data of two diagonal points of the map image for coordinate calculation are acquired from the QR code.

  In the subsequent step S261, the computer 12 looks at the image data stored in the image buffer and determines whether or not the mark 102 as shown in FIG. 27 is entered. If "YES" is determined in the step S261, the computer 12 subsequently proceeds to the steps similar to the steps S209 and S215 of FIG. 26 described above and illustrated in detail in FIGS. 29 and 32, respectively. Steps S263 and S265 are executed to obtain the longitude and latitude data in which the mark 102 is written, and in step S267, the coordinate data is stored in the data storage area 28 (FIG. 2).

  If “NO” is determined in the step S261, the computer 12 determines that the polygon 102a is entered on the map image as shown in FIG. 33, and proceeds to the next step S269. In this step S269, processing for calculating the coordinates of the outline of the polygon 102a extracted and shown in FIG. 34 is executed, the details of which are shown in the flowchart of FIG.

  In the first step S281 of FIG. 36, the coordinates of all the meshes forming the polygon 102a are calculated according to the previous equation 3 based on the diagonal coordinates acquired in step S259 of FIG. save.

  In the next step S283, the computer 12 acquires the maximum value and minimum value (Xmaz, Xmin) in the X direction and the maximum value and minimum value (Ymax, Ymin) in the Y direction at the acquired coordinates of each mesh.

  In subsequent step S285, the computer 12 acquires the maximum value and the minimum value in the Y direction with respect to the maximum value from the minimum value in the X direction in the coordinates of all the meshes. Referring to FIG. 34, first, the minimum value in the X direction of all meshes is “10”, and the maximum value is “21”. When X = 10, there are three meshes in the Y direction, the minimum value is “9”, and the maximum value is “11”. In the next X = 11, five meshes are arranged in the Y direction from the minimum value “8” to the maximum value “12”. Thus, when the minimum value and the maximum value of the Y position for each X position are obtained, the result is as shown in Table 1.

  In the next step S287, the computer 12 acquires the maximum value and the minimum value in the X direction with respect to the maximum value from the minimum value in the Y direction in the coordinates of all the meshes. In the example of FIG. 34, the minimum value in the Y direction is “5”, and the maximum value is “15”. At the position of Y = 5, there are three meshes in the X direction, and the minimum value is “15” and the maximum value is “17”. At the next position of Y = 6, five meshes are arranged in the X direction from the minimum value “14” to the maximum value “18”. When the minimum value and maximum value of the X position with respect to each Y position are obtained, the result is as shown in Table 2.

In subsequent step S289, the computer 12 extracts the coordinates of the outline of the polygon 102a based on the results of Tables 1 and 2 above. Specifically, the coordinates of the outline can be extracted by eliminating the overlapping coordinates from all the acquired coordinates. For example, according to Table 1, the coordinates of the mesh forming the outline are (10,11), (10,9), (11,12), (11,8), (12,13), (12,8) According to Table 2, (17,5), (15,5), (19,6), (14,6) ... Such outline mesh coordinate data is stored in the data storage area 28.

  Thereafter, the process proceeds to step S271 in FIG. 35 to execute polygon calculation processing shown in detail in FIG.

In the first step S291 in FIG. 37, the computer 12 searches for the coordinate whose (X, Y) is the minimum value among the outline coordinates acquired in step S289. In the example of FIG. 34, it is (10, 9). Then, in the next step S293, until the start point mesh is detected in step S295, the minimum coordinate is set as the start point, and the outer coordinates are found in the right direction. Assuming that the minimum value coordinate is (10, 9), the next right outline coordinate is (11, 8), and the next is (12, 8). In the same manner, if the search is performed up to (10, 10), the next is the start point of (10, 9), so “YES” is determined in step S295, and the process proceeds to the next step S297 to perform the search. Generate polygon data of a polygon surrounded by outline coordinates. As described above, since the coordinates of all the meshes forming the outline are known, printing of the result of decoding the QR code 78 by using the same method as the coordinate conversion described above with reference to the flowchart of FIG. Polygon data can be generated by converting into longitude and latitude data based on the longitude and latitude of a specific position of the frame. That is, the polygon data is a data group including an enumeration of longitude and latitude data of all meshes forming the outline of the polygon 102a indicating the region.

  The polygon data generated in this way is useful for estimating a disaster area by processing (for example, in the form of logical product) in combination with other map data (layer).

  The map illustrated in FIG. 15 can be used as part of the survey form shown in FIG. 38 or FIG. 39, for example.

  The example of FIG. 38 shows a survey form 118 used for the purpose of investigating the state and position of a collapsed house after the earthquake disaster, and this survey form 118 is printed on a sheet 74. A text printing unit 120 is formed on the left side of the paper 74. The text printing unit 120 is omitted in the drawing, but in addition to predetermined items such as the name and address of the subject, questions necessary for the collapsed house survey and Investigator name entry fields indicating the surveyed personnel are appropriately formed. Further, a survey ID entry field 82a for entering a survey number (ID) by handwriting is formed in the text printing unit 120. A map printing unit 122 is formed on the right side of the sheet 74, and the map image 76, the QR code 78, etc. previously illustrated in FIG. The survey ID entry column 82a of the text printing unit 120 is paired with the survey ID entry column 82b formed in the map printing unit 122, and the surveyor enters the same survey ID in the two entry columns 82a and 82b.

  In order to print the survey form 118 with the printer 22 (FIG. 1), it is necessary to input necessary text data to the text printing unit 120 and adjust it to a predetermined format. You can use an application such as MS Word or Excel (both are Microsoft product names).

  In the printer setting described above, “A4” is assumed as the paper size. Therefore, when the survey form 118 is printed on the “A3” size paper, map printing is performed in addition to changing the printing direction. There is no need to change settings such as margins. This is because the map is printed in the A4 size portion of the right half of the A3 paper. In that case, the text printing unit 118 can also use the print settings for the A4 size as they are.

  However, when the size of the survey form 118 is other than A3, for example A4, both the text printing unit 120 and the map printing unit 122 have half the A5 size, so the print settings set in the A4 size are adjusted to the paper size. Change is required.

  The survey form 118 illustrated in FIG. 39 is suitable for investigating the damage situation of a certain area (area) rather than investigating the damage situation of each house. Therefore, the text printing unit 120 of the survey form 118 of this embodiment is printed with items capable of investigating a widespread disaster such as a sediment disaster, fire, or flood damage. The map printing unit 122 is printed with a map 76, a QR code 78, and the like similar to the survey form in FIG.

  When the survey form 118 of FIG. 39 is used, the disaster area is entered on the map image 76 as the polygon 102a. By reading the survey form and collating it with a population layer or a house layer, which is one of the map data included in the map database 20, it is possible to grasp the extent of damage (human or house, etc.) in that area. .

  Further, the survey forms shown in FIGS. 38 and 39 are merely examples, and other survey forms for investigating crime damage that need to specify the location of occurrence are also conceivable.

  If a disaster investigation or the like is performed by using these survey forms 118, there is an advantage that the disaster location and the disaster location can be accurately identified.

  In the embodiment of FIG. 40, another example of the map operation GUI 32 is shown, and a print frame 52 for four pages is displayed superimposed on the map display area 36. Referring to FIG. 40, a print frame setting button 48a is displayed in the operation setting area 34a of the map operation GUI 32 in place of the print frame specifying button 48. When the print frame setting button 48 a is operated, the print frame setting GUI 124 is displayed so as to be superimposed on the map display area 36. In the print frame setting GUI 124, a print number setting button 126 is displayed together with a scale setting unit 38a and a number setting window 50a. The print number setting button 126 is a button for setting the number of sheets to be printed for each page.

  FIG. 41 shows the print number setting GUI 128 displayed when the print number setting button 126 is operated. In addition, the number-of-prints setting GUI 128 displays the page number designation sections 130a to 130d shown in FIG. For example, when printing only two pages and printing the remaining 1, 3, and 4 pages, “2” is input to the number designation portion 130b, and the other number designation portions 130a, 130b, and 130c. “1” is input to. Then, after the setting button 132 is operated, when the print execution button 70 of the print frame setting GUI 124 is operated, each page is printed as set. That is, only the second page is printed twice, and the other pages are printed one by one. When the cancel button 134 is operated, the result input to each number designation unit 130 is not reflected, and even if the print execution button 70 is operated, all pages are printed one by one.

  In this way, the user-friendliness is improved because the number of printed pages can be individually specified on an arbitrary page.

  Although the scale setting unit 38, the printer setting button 44, the move button 53, the copy number setting window 50, and the print button 72 are not displayed in the operation setting area 34a, these buttons are displayed on the print frame setting GUI 124. . Further, although not indicated by reference numerals, a key for enlarging / reducing the map image itself displayed in the map display area 36 is further displayed in the operation setting area 34a. Further, the print frame setting GUI 124 includes a button for designating an image to be inserted on the left side of the survey form 118 shown in FIG. 38, a radio button for designating the insertion position, and a start position of a serial number given to the survey form 118. Input frame to be specified, button to create a new print frame, button to delete the set print frame, button to read the print frame setting already stored, button to delete the print frame setting already stored, etc. Is further displayed.

  The example of FIG. 42 shows another example of the printed map, and the map image 76a is printed on the paper 74 as in FIG. In this embodiment, a numerical value at the 1's position of the mesh coordinates is described around the map image 76a so that the coordinate position of the mesh can be easily recognized. Further, the map image 76a is printed with the first QR code 78a superimposed on the upper left corner and the second QR code 78b superimposed on the lower right corner.

  Referring to FIG. 43A, in the upper left corner K1, the upper left corner of the first QR code 78a matches the upper left corner of the map image 76a. Referring to FIG. 43B, the lower right corner of the second QR code 78b coincides with the lower right corner of the map image 76a at the lower right corner K2, which is the diagonal of the upper left corner K1. That is, printing is performed so that the corners of the first QR code 78a and the corners of the second QR code 78b coincide with each of the diagonal vertices of the map image 76a. In the first QR code 78a and the second QR code 78b, the longitude and latitude indicated by the longitude and latitude portion 136 are encoded. In other words, the reliability of the process of decoding the QR code is improved by superimposing a plurality of QR codes on the map image 76a.

  In this embodiment, when the image data corresponding to the map image 76a and the two QR codes are transferred to a printing memory (not shown) built in the printer 22, the print positions of the image data are matched. By doing so, the corners of the two QR codes and the map image 76a are matched. In other words, by matching the print positions of the two types of image data, an image in which the corners of the two QR codes and the map image 76a match is printed. The printing memory is a memory that stores each pixel of image data to be printed in correspondence with the raster scan direction. That is, the reading start position of the printing memory corresponds to the upper left of the image data, and the reading end position corresponds to the lower right of the image data. Accordingly, when the printing positions are matched, the image data corresponding to the first QR code 78a is transferred so that the upper left pixel matches the reading start position of the printing memory, and the image data corresponding to the second QR code 78b. Is transferred so that the lower right pixel coincides with the reading end position of the printing memory.

  In this way, by printing two types of image data superimposed without using many layers, the usage rate of the memory 18 can be suppressed, and a decrease in the processing speed of the computer 12 can be prevented. In particular, when printing a large amount of maps, the above effects are exhibited.

  Further, by using the large-capacity memory 18, the corners of the two QR codes and the map image 76a may be matched using a layer. In this case, two layers having the same size are set, a map image is drawn on the back layer, and two QR codes are drawn on the front layer. Then, the corner of the first QR code 78a may coincide with the upper left (origin) in the front layer, and the corner of the second QR code 78b may coincide with the lower right in the front layer. Furthermore, image data for printing is created based on the two layers, and the image data is transferred to a printing memory (not shown) so that the corners of the two QR codes coincide with the map image 76a. Images can be printed.

  Furthermore, in this embodiment, when decoding the QR code, pixel values at the four corners of the QR code can be obtained individually. The pixel value is a value indicating a position for each pixel in an image scanned by the scanner 24 or the like. For example, when the scanning resolution of the scanner 24 is set to 300 dpi and an A4 size paper 74 is scanned, the total number of pixels of the image corresponding to the paper 74 is “2480 pixels × 3508 pixels”. At this time, if the upper left corner Po of the paper 74 in FIG. 43A is the origin (0, 0), the pixel value of the upper left corner K1 is (113, 86), and the pixel value of the lower right corner K2 is (2348, 3151).

  However, the reading program 263 of this embodiment includes a “QR Code Decode Library (http://www.psytec.co.jp/product/03/)” provided by Psytec Co., Ltd. as a library. The library is used for the processing of individually acquiring the pixel values of the four corners.

  Here, in this embodiment, the detailed longitude and latitude in the map image 76a can be obtained from the pixel values of the upper left corner K1 and the lower right corner K2 and the longitude and latitude corresponding to the upper left corner K1 and the lower right corner K2. Become.

  For example, the user marks the map image 76a printed on the paper 74 as in the previous embodiment. That is, the user can give the longitude and latitude to be recognized with respect to the printed map by the handwritten mark 102a (FIG. 45). In this case, the selection process described below performs conversion according to the geodetic system from the pixel value of the mark 102a and the pixel value of the paper map image indicated by the QR code, and the process of the pixel value (coordinates) to which the mark 102a is assigned. Calculate the degree. That is, for the map shown in FIG. 42, a map with a mark such as red is read by an image reader, and the QR code and the pixel value of the mark written on the map are detected. Based on the longitude and latitude coordinates of the upper left and lower right coordinates of the map embedded in the QR code, the pixel value corresponding to the mark 102a is converted to the longitude and latitude used as GIS data, and the conversion result is data in CSV format or the like. Output to the outside.

  Therefore, as in the previous embodiment, when reading a map, the reading position can be converted to the longitude and latitude even if the reading computer does not have map data such as a GIS database.

  The basic operation of the reading process is shown in the flowchart of FIG. 44, the reading GUI 138 shown in FIG. 45 is displayed on the monitor 16 (FIG. 1). The reading GUI 138 is an image display area 142 on the left side, and the read image data is displayed as it is in the image display area 142. Here, an image (such as a map image or QR code on the paper 74) obtained by reading the paper 74 shown in FIG. 46 by the scanner 24 is displayed as it is. In the following description, it is assumed that a mark 102a such as red is written in the selected image data.

  A selection button 140 is formed above the image display area 142. The selection button 140 is a button for selecting image data stored in the data storage area 28 of the memory 18 using a GUI (not shown). In addition, a code analysis button 144 is formed on the right side of the selection button 140. When the code analysis button 144 is operated, the total number of QR codes included in the image data is displayed on the display unit 146 near the upper center. Is displayed. The longitude and latitude values embedded in the first QR code 78a and the second QR code 78b are displayed on the analysis result display unit 148 formed on the lower side of the display unit 146. Furthermore, numerical values of the upper left longitude and the lower right longitude are displayed on the longitude and latitude display portion 150 formed below the analysis result display portion 148.

  In addition, a reference point display unit 152 is formed below the longitude and latitude display unit 150, and a pixel value at the upper left corner K1 and a pixel value at the lower right corner K2 are displayed here. Furthermore, the division number display unit 154 formed on the upper side of the analysis result display unit 148 displays the number of pixels on the X (vertical) axis and Y (horizontal) axis of the image data corresponding to the map image 76a.

  Further, a pixel value display unit 156 and a position coordinate display unit 158 are formed below the reference point display unit 152. The pixel value display unit 156 displays a numerical value indicating the pixel value corresponding to the mark 102a (FIG. 46), and the position coordinate display unit 158 displays a numerical value indicating the longitude and latitude indicated by the mark 102a.

  Note that an input unit 160 and a Map button 162 are formed below the pixel value display unit 156 and the position coordinate display unit 158. The user inputs a numerical value indicating the longitude and latitude displayed on the position coordinate display unit 158 to the input unit 160, and operates the Map button 162 formed on the right side thereof, thereby monitoring the digital map via the network. 16 can be displayed. That is, when the Map button 162 is operated, the computer 12 accesses a digital map providing service site (for example, Google (registered trademark) map) using the network, and the digital map provided by the site is displayed on the monitor 16. indicate.

  46 is set in the scanner 24 and such a reading GUI 138 is displayed in step S301, the computer 12 determines in step S303 whether or not an image capturing operation has been performed by the user. If “YES” is determined in the step S303, the scanner 24 is operated in a subsequent step S305 to scan one sheet, and the acquired image is stored in the data storage area 28 (FIG. 2) of the memory 18 in a step S307. The image is temporarily saved in a set image buffer (not shown), and the saved image is displayed in the image display area 142 of the reading GUI 138. Further, the image displayed in the image display area 142 can be freely enlarged or reduced by the user operating an enlargement / reduction button (not shown).

  Subsequently, in step S309, the computer 12 executes mark position recognition processing. Specifically, the mark position recognition process is achieved by executing the flowchart shown in FIG.

  47 is executed, the computer 12 recognizes the mark 102a (FIG. 46) attached by the user. If it can be recognized, the process proceeds to step S325, and the computer 12 stores the mark pixel values (px3, py3) shown in FIG. 48 in a mark pixel value register (not shown) in the data storage area 28 (FIG. 2) of the memory 18. save. If “NO” in the step S223, “null” is written as a pixel value in the mark pixel value register in a step S327.

  Note that the pixel value of the mark represents the position of the pixel in the map image 76a, not the coordinate position of longitude and latitude. The upper left corner K1 (FIG. 44) is stored as a pixel value (px3, py3) with the pixel value as the origin Po and the number of pixels in the vertical and horizontal directions. In this embodiment, the pixel value of the mark 102a corresponds to the cross point of the cross mark.

  Returning to step S311 of FIG. 44, the computer 12 executes QR code recognition processing shown in detail in FIG.

  The computer 12 recognizes the first QR code 78a (FIG. 46) and the second QR code 78b by executing the first steps S331 and S333 of FIG. If it can be recognized, the process proceeds to step S335, and the longitude and latitude corresponding to the geodetic system, that is, the upper left coordinates (Lx1, Ly1) and lower right coordinates (Lx2, Ly2) shown in FIG. It is stored in the longitude and latitude coordinate register (not shown) of 2). Further, in steps S337 and S339, the coordinate pixel value (px1, py1) of the upper left corner K1 and the pixel value (px2, py2) of the lower right corner K2 are stored in the pixel value register (FIG. 2) of the data storage area 28 (FIG. 2). (Not shown). If “NO” in the step S333, “null” is written as the latitude and longitude and the pixel value in the longitude and latitude coordinate register and the pixel value register in a step S341.

  Returning to step S313 in FIG. 44, the computer 12 determines whether or not there was an error in the previous steps S309 and S311, that is, whether or not “null” was written in any of the registers in the two steps S309 and S311. to decide. If it is determined that there is no error, coordinate conversion processing is executed in the next step S315. Specifically, the coordinate conversion process is achieved by the flowchart shown in FIG.

  In the first step S351 of FIG. 50, the computer 12 obtains the pixel value (px1, py1) of the upper left corner K1 and the pixel value (px2, py2) of the lower right corner K2 shown in FIG. 48 acquired by the QR code recognition process of FIG. Are read from the pixel value register in the data storage area 28. Subsequently, in step S353, the upper left coordinates (Lx1, Ly1) and lower right coordinates (Lx2, Ly2) shown in FIG. 48 acquired in the QR code recognition process are read from the longitude and latitude coordinate registers. Further, subsequently, in step S355, the pixel value (px3, py3) of the mark shown in FIG. 48 acquired by the mark position recognition process shown in FIG. 47 is read from the mark pixel value register.

  In step S357, the computer 12 calculates the number of pixels on the horizontal axis and the vertical axis as the division amount based on the pixel value (px1, py1) at the upper left corner K1 and the pixel value (px2, py2) at the lower right corner K2. . Subsequently, in step S359, a difference between longitude and latitude is calculated based on the upper left coordinates (Lx1, Ly1) and the lower right coordinates (Lx2, Ly2). Note that the division amount calculated in step S357 is stored in a division amount register (not shown) in the data storage area 28 (FIG. 2) of the memory 18. The stored division amount is displayed on the division amount display unit 154 in the reading GUI 138.

  Subsequently, in step S361, the X-axis pixel value px3 of the mark 102a marked by the user is converted into the X coordinate according to Equation 6, and in the next step S363, the Y-axis pixel value py3 of the mark 102a is converted into the Y coordinate. To do.

  For example, the X-direction length of the entire map can be calculated by subtracting the upper left X coordinate Lx1 from the lower right X coordinate Lx2, and the X axis pixel value px1 of the upper left corner K1 can be calculated from the X axis pixel value px2 of the lower right corner K2. By subtracting, the number of pixels in the X direction of the entire map can be calculated. Further, by dividing the length in the X direction by the number of pixels in the X direction {(Lx2-Lx1) / (px2-px1)}, the X direction length of one pixel can be calculated. Furthermore, the position of the mark 102a on the map image can be calculated by subtracting the X-axis pixel value px1 at the upper left corner K1 from the X-axis pixel value px3 of the mark 102a. Then, by adding the value obtained by multiplying the X-coordinate Lx1 of the upper left by the X-direction length of one pixel to the position of the mark 102a on the map image, the numerical value of the geodetic system in the X direction of the mark 102a, that is, the longitude is obtained. .

On the other hand, the length in the Y direction of the entire map can be calculated by subtracting the upper left Y coordinate Ly1 from the lower right Y coordinate Ly2, and the Y axis pixel value py1 of the upper left corner K1 from the Y axis pixel value py2 of the lower right corner K2. The number of pixels in the Y direction of the entire map can be calculated by subtracting. Further, by dividing the length in the Y direction by the number of pixels in the Y direction {(Ly2-Ly1) / (py2-py1)}, the Y direction length of one pixel can be calculated. Further, the position of the mark 102a on the map image can be calculated by subtracting the Y-axis pixel value py1 at the upper left corner K1 from the Y-axis pixel value py3 of the mark 102a. Then, by adding the value obtained by multiplying the Y-coordinate Ly1 of the upper left by the Y-direction length of one pixel to the position of the mark 102a on the map image, the numerical value of the geodetic system in the Y direction of the mark 102a, that is, the latitude is obtained. .
[Equation 6]
X coordinate = Lx1 + [{(Lx2-Lx1) ÷ (px2-px1)} × (px3-px1)]
Y coordinate = Ly1 + [{(Ly2-Ly1) ÷ (py2-py1)} × (py3-py1)]
Thus, in step S365, the longitude and latitude corresponding to the GIS data is (X, Y).
Confirm.

  However, when “NO” is determined in step S313 of FIG. 44, that is, when recognition of either the mark position or the QR code fails, an error value is set for the mark position and / or the QR code. Then, the user can call a page determined to be an image recognition result error and perform correction input of the mark position and / or QR code.

  Note that the longitude and latitude data determined in step S315 of FIG. 44, that is, step S365 of FIG. 50, is output as a record as a CSV file.

  In this manner, the pixel value of the mark 102a can be converted into GIS data by reading the image data of the map paper 74 on which the mark 102a is entered as shown in FIG.

  With the above processing, even if the position where the map image 76a is printed differs for each sheet, the pixel value of the upper left K1 of the map image 76a for each sheet can be acquired as the offset value. Further, since the origin of the map image 76 can be obtained based on the offset value, the longitude and latitude can be calculated for each pixel. That is, the longitude and latitude can be obtained with higher accuracy than the calculation of longitude and latitude based on the mesh.

  In the above-described embodiment, the diagonal longitude and latitude of the printed map image is encoded with a QR code and printed on a sheet together with the map image. However, in order to encode the diagonal longitude and latitude of the map image, in addition to the two-dimensional barcode such as a QR code, a one-dimensional barcode or other encoding method may be adopted. The code needs to be read by the scanner together with the map image after the user enters a mark or polygon. That is, as long as it can be read by the scanner, a code image by an arbitrary encoding method can be used.

  In the above-described embodiment, the fine line of the mesh is printed by superimposing it on the map image. However, this mesh does not need to be printed. The longitude and latitude of the position may be calculated, or polygon data may be generated. That is, not only when the mesh is actually printed, but also when the computer virtualizes the mesh, the mesh is superimposed on the map image.

  Further, in the above-described embodiment, instead of “QR Code Decode Library”, the pixel values of the four corners of the QR code can be individually acquired by using another library or using dedicated software. It may be.

  Furthermore, in any of the above-described embodiments, a rectangular print frame is set as the print frame, and the diagonal background is set as a specific position on the print frame or in the print frame, that is, a specific position related to the print frame. The degree is converted into a code image such as a QR code. However, the printing frame is not necessarily rectangular, and a circle or other polygon may be designated as the printing frame. In the code image, information such as longitude and latitude at a specific position of the print frame, for example, each vertex angle of the polygon, and the longitude and latitude at the center in the case of a circle may be embedded in the code image.

  In this case, the reading device can decode the code images to obtain the longitudes and latitudes of those specific locations, and calculate based on them to identify the longitude and latitude of the position and location marked by the user.
