Description

  The present invention relates to a technology for supporting creation of a cadastral display map showing a cadastral map, such as a cadastral map, a public chart, a cadastral survey map, and a cadastral survey chart.

  As a technology for supporting the creation of a map, a polygon (polygon) representing a section is drawn on the map in response to a user operation, or a user selects from a plurality of symbols (marks, symbols) prepared in advance. 2. Description of the Related Art A map creation device that facilitates a user's map creation work by drawing a symbol at a position designated by the user on a map is known (for example, Patent Document 1).

Prior art document information relating to the invention of this application includes the following.
Japanese Patent Laid-Open No. 10-116337

  Now, the land of the same brush on the land register may actually exist as two sections separated by roads and waterways that occur after registration. Such land is called glasses ground, and is a glasses ground symbol that has a shape like glasses consisting of two circles arranged one by one in each section and an arc-shaped line segment connecting the two circles. By connecting the two sections constituting the place of glasses, it is shown that the two sections are the places of glasses on the land register display diagrams such as the land register map and the public map. In addition, for such glasses, it is usually supposed that information on the brush of the owner or the like is written only in one of the two sections constituting the glasses.

  By applying a technique for arranging a symbol selected by the user from the plurality of symbols prepared in advance at the position specified by the user on the map, the following problems occur. Occurs. That is, first of all, the two sections constituting the glasses are two sections separated from each other, and the distance of the separation differs depending on the individual glasses. The glasses ground symbol cannot be prepared fixedly in advance. For this reason, as in the above-described conventional technique, using a fixed-form, fixed-size pre-prepared glasses symbol, it is not possible to connect the two sections constituting the glasses with the glasses-ground symbol. That is, there is a case where the glasses ground symbols cannot be arranged so that the small circles of the glasses ground symbols are arranged one by one in each section. On the other hand, it is possible to arrange the glasses symbol so as to connect the two sections constituting the glasses by using the scale symbols prepared in advance and reducing the size of the glasses. There may be a case where the glasses section symbol does not fit between the two sections and the space between them and the space for displaying other information in the section may be lost due to the glasses section symbol. For this reason, the user has to draw the spectacle symbol individually for each spectacle location in order to display an appropriate spectacle symbol on the map.

Next, as described above, the two sections constituting the glasses have the same information about the brush of the owner, etc. In addition, in public maps, etc., only one of the two sections constituting the glasses is used for writing. It may be necessary to display the information.
For this reason, the user has to perform operations such as setting whether or not to display brush information for each of the sections constituting the glasses. In addition, when setting brush information as an attribute for each section on the cadastral display map, the redundant work of setting the same brush information for two sections constituting the glasses place is necessary.

As described above, conventionally, the user has been required to perform various complicated operations regarding the place of spectacles when creating the cadastral display map.
SUMMARY OF THE INVENTION An object of the present invention is to facilitate the user's work for setting the location of spectacles when creating a cadastral display map.

  In order to achieve the object, the present invention provides an image display means for displaying a partition display image in which a partition graphic representing each partition is drawn, and a partition represented by the partition graphic for each partition graphic in the partition display image. The setting operation of the cadastral attribute item of the brush belonging to the user is accepted from the user, and the cadastral attribute item for which the setting operation has been accepted is set as an attribute of the partition graphic, and two separate on the display of the partition display image Accepts a setting operation of a glasses place symbol indicating on the section display image that the section is a place of glasses, and draws a place place symbol on the section display image; and the place symbol to draw the glasses At least one of the cadastral attribute items set as an attribute in one of the section graphics of the two sections indicating that it is a land on the section display image Parts, and provides a cadastral display view processing system including an attribute succession means for setting an attribute of the other compartment shapes.

  According to such a cadastral display map processing system, the user simply sets the sight symbol, and at least one of the cadastral attribute items of the two sections representing the sight of the glasses by the glasses territory symbol. A part can be set in the cadastral attribute item of the other section. Therefore, the user does not need to perform the redundant work of setting the same value for these cadastral attribute items in the two sections constituting the glasses.

  In order to achieve the above object, the present invention represents an image display means for displaying a partition display image in which a partition graphic representing each partition is drawn, and the partition graphic for each partition graphic in the partition display image represents The setting operation of the cadastral attribute item of the brush to which the section belongs is accepted from the user, and the attribute processing unit that sets the cadastral attribute item that has received the setting operation as an attribute of the section graphic is separated from the display of the section display image A setting symbol symbol setting operation for accepting a setting symbol symbol indicating that the two divisions are glasses on the division display image, drawing a glasses symbol on the division display image, and at least the cadastral attribute item A part is displayed as a display item, and the value of the display item set as an attribute is drawn on the partition display image in association with each partition graphic. Register attribute drawing means, and in the cadastral attribute drawing means, one of the two section graphics of the section display image showing that the drawing symbol is drawn on the section display image A cadastral display map processing system is provided in which the value of the display item is drawn only for the other, and the value of the display item is not drawn for the other partition graphic.

  According to such a cadastral map display processing system, the user simply sets the glasses ground symbol, and one of the two sections represented by the glasses ground symbol as the glasses ground on the section display image. Only the owner can display the cadastral attribute item of the brush of the glasses such as the owner. Therefore, the user does not need to perform operations such as setting the presence / absence of the display of the cadastral attribute item for each of the sections constituting the glasses.

  In order to achieve the above object, the present invention further provides an image display means for displaying a partition display image in which a partition graphic representing each partition is drawn, and two partitions separated on the display of the partition display image. A cadastral symbol display processing system is provided that includes a setting symbol symbol drawing unit that accepts a setting symbol symbol operation that indicates on the section display image that it is a spectacle display area, and draws the spectacle position symbol on the section display image. To do. Here, the glasses place symbol drawing means includes a point accepting means for accepting designation of two points on the section display image from a user, and a first point centered on a first point of the two points accepting the designation. A circle and a second circle having the same radius as the first circle centered on the second point out of the two points that received the designation are drawn, and the two points are defined as two vertices at both ends of the base. Centered on a point equal to the position of the remaining vertex of one isosceles triangle (including an equilateral triangle), a length less than the radius of the first circle is added to the length of the equal side of the isosceles triangle A third circle having a radius equal to the length, a center of curvature and an arc having the same radius of curvature, and a point equal to the intersection of the first circle and the third circle on the second circle side; , A point equal to the intersection of the second circle and the third circle on the first circle side; As both ends, and a spectacle locations symbol drawing means for drawing an arc does not intersect with the first circle and the second circle.

  According to such a cadastral display map processing system, the size of the two circles forming the glasses ground symbol can be appropriately determined only by designating the two points where the two circles of the glasses ground symbol are arranged on the division display image. While maintaining the size, only the arc-shaped line segment connecting the two circles can be drawn on the partition display image with the appropriate glasses place symbol expanded and contracted according to the distance between the two sections constituting the place of the glasses.

In such a cadastral display map processing system, it is also preferable that the base angle of the isosceles triangle is increased as the distance increases, depending on the distance between the first point and the second point.
By doing in this way, even when the distance between the said 1st point and the 2nd point is large, it can suppress that the arc-shaped line segment which connects two circles swells greatly.

  As described above, according to the present invention, it is possible to facilitate the user's work of setting the spectacles at the time of creating the cadastral display map.

If the corresponding symbol type is a glasses symbol, the symbol attribute indicates the polygon attribute data indicating the polygon attribute data of two polygons representing the section constituting the glasses corresponding to the glasses symbol. The polygon attribute data and the parent polygon attribute data indicating the polygon attribute data of one polygon which is the main polygon constituting the brush among the two polygons are described.

Hereinafter, operation | movement of the land-register map processing part 5 of such a land-register display map processing system is demonstrated.
The process control unit 52 first displays the work window shown in FIG. 3 on the display device 1 via the GUI control unit 51.
As shown in the drawing, the work window includes a command button row 301, a land register display area 302 provided on the left side, and a tool window group 303 provided on the right side. A cursor 304 is displayed in the work window.
The cadastral map display area 302 is an area for displaying the cadastral map to be edited. The graphic processing unit 53 displays the polygon layer and symbol layer of the cadastral map graphic data, and the brush information display in which the graphic processing unit 53 determines the drawing contents. An image in which layers are drawn from the bottom in the description order and displayed is displayed. The process of determining the drawing content of the brush information display layer of the graphic processing unit 53 will be described later.

  The enlargement button, the reduction button, and the move button in the command button row 301 are buttons for enlarging, reducing, and scrolling the cadastral map displayed in the cadastral map display area 302. Further, in the command button column 301, a new button is a button for creating a new cadastral map as a cadastral map to be edited, and an open button is a button for calling an existing cadastral map as a cadastral map to be edited, The save button is a button for saving the cadastral map to be edited, the print button is a button for printing the cadastral map to be edited, and the end button is a button for ending the process.

The tool window group 303 includes tool windows such as an attribute setting tool window 3031, an editing tool window 3032, and a layer tool window 3033.
Each tool window of the tool window group 303 is activated and displayed in the foreground by selection with a tab 304 provided at the top of each tool window, and the tool window that accepts an operation in the tool window is the topmost. Switch to the tool window displayed in the foreground. The operation of each tool window, command button, and cursor 304 is accepted by the processing control unit 52 via the GUI control unit 51, and the processing control unit 52 performs processing according to the operation by itself or according to the operation. The graphic processing unit 53, the attribute processing unit 54, and the drawing output processing unit 55 perform the above processing.

The attribute setting tool window 3031 is a tool window for setting the brush information of the polygon attribute data of each polygon of the cadastral map to be edited.
That is, as shown in FIG. 3, in a state where the attribute setting tool window 3031 is active and displayed in the foreground, the processing control unit 52 accepts selection of the polygon 3021 by the cursor 304 and in the attribute setting tool window 3031. When the setting of each item of the brush information described above is accepted and the attribute information of the selected polygon 3021 does not exist in the brush information of the polygon attribute data of the selected polygon 3021 via the attribute processing unit 54 Set it after creating a new one. However, in the attribute tool window 3031, when the cadastral ID is input and the read button 30311 is operated, the cadastral database 56 has the cadastral ID entered by the user by the attribute processing unit 54. By reading and setting other items (brush attributes) of the brush information from the book record, a process for saving the user's settings for these other items is performed. In addition, if a type of ground is set for the type of brush information in the polygon attribute data of the selected polygon, the type of the symbol attribute in the symbol attribute data pointed to by the corresponding symbol attribute data described in the type For each item of the brush information of the polygon attribute data of the polygon other than the selected polygon registered in the polygon data, the value set in the corresponding item of the brush information of the polygon attribute data of the selected polygon is set. Like that.

  Next, the layer tool window 3033 is a tool window for controlling each layer of the cadastral map. In the state where the layer tool window 3033 is active and displayed in the foreground, the process control unit 52 performs the cadastral editing. The selection of layers in the figure and the setting of the display mode and print mode of each layer are accepted and set on the layer tool window 3033.

Next, the editing tool window 3032 is a tool window for editing polygons in the polygon layer and symbols in the symbol layer.
When the tool window becomes active when the polygon layer is the editing target layer, the processing control unit 52 draws the polygon on the cadastral map in the cadastral map display area in the editing tool window 3032 displayed in the foreground. And a graphic processing unit 53 is caused to perform editing such as drawing, correction, and deletion of the polygon on the polygon layer in accordance with a user operation using the tool.

  Further, when the tool window becomes active when the symbol layer is a layer to be edited, the processing control unit 52 adds the symbol to the cadastral map in the editing tool window 3032 as shown in FIG. Displays tools for drawing on the cadastral map in the display area, and edits polygons on the symbol layer according to user operations using this tool, such as drawing, modifying, and deleting, as well as symbol data for symbol layer data Processing according to the editing contents such as new creation, update, and deletion.

  That is, the processing control unit 52 accepts the selection of the type of symbol to be drawn according to the selection of the symbol tool 30321 provided in the editing tool window 3032 by the cursor 304, and the position on the cadastral map in the subsequent cadastral map display area In response to the designation by the cursor 304, the graphic processing unit 53 is caused to draw a symbol of a fixed size and a fixed shape prepared in advance of the selected type at the designated position of the symbol layer of the cadastral map. Further, the drawn symbol attribute data is generated and stored in the cadastral map attribute data of the cadastral map data.

When the spectacles setting button provided in the editing tool window 3032 is operated, the following spectacles setting processing is performed.
FIG. 5 shows the procedure of the glasses place setting process.
As shown in the figure, in this process, first, as shown in FIG. 4b, designation by the cursor 304 of the position on the cadastral map in the cadastral map display area is accepted, and the designated position is acquired as the first point (step 502). . Then, the polygon including the first point is obtained as the first polygon with reference to the polygon layer data, and it is checked whether or not the polygon attribute data of the first polygon satisfies the first glasses candidate condition (step 504). Here, as the first glasses candidate site condition, a; type does not indicate a narrow or narrow object such as a road or a waterway. b: The type does not indicate glasses. Two conditions are set.

If the polygon attribute data of the first polygon does not satisfy the first glasses location candidate condition, a predetermined error message is displayed on the display device 1 via the GUI control unit 51 (step 524), and the process ends. .
On the other hand, if the polygon attribute data of the first polygon satisfies the first glasses candidate condition, a small circle 401 centered on the first point is drawn on the symbol layer as shown in FIG. 4c (step 506). Here, the radius of the small circle 401 may be fixed, but is preferably determined according to the scale of the land register (the ratio of the distance unit of the coordinate system used by the land register figure data to the actual distance unit) or the like. .

Next, as shown in FIG. 4d, designation by the cursor 304 of the position on the cadastral map in the cadastral map display area is accepted, the designated position is acquired as a second point (step 508), and drawing on the symbol layer in step 506 The small circle 401 is erased (step 510).
Then, a polygon including the second point is obtained as a second polygon with reference to the polygon layer data, and it is checked whether or not the polygon attribute data of the second polygon satisfies the second glasses ground candidate condition (step 512). Here, as the second glasses candidate site condition, a; type is not a narrow or narrow object such as a road or a waterway. b: The type is not already a place of glasses. c: the first polygon and the second polygon are not in contact, d: different large letters, small letters, lot numbers, and owners are registered in the brush information of the attribute data of the first polygon and the brush information of the attribute data of the second polygon Absent. The following four conditions are used. However, if at least one of the brush information of the attribute data of the first polygon and the brush information of the attribute data of the second polygon is not set, the upper case, the lower case, the lot number, and the owner match. It is considered.

If the polygon attribute data of the second polygon does not satisfy the second glasses candidate condition, a predetermined error message is displayed on the display device 1 via the GUI control unit 51 (step 524), and the process is terminated. .
On the other hand, if the polygon attribute data of the second polygon satisfies the second glasses candidate condition, the glasses symbol 402 is drawn on the symbol layer as shown in FIG. 4e (step 514). Details of the drawing method of the glasses symbol 402 will be described later.
Next, whether or not the brush information is set in any one of the brush information of the attribute data of the first polygon and the brush information of the attribute data of the second polygon and the brush information is not set in the other. Check (step 516), otherwise proceed to step 518. On the other hand, if the brush information is set to any one and the brush information is not set to the other, the brush information of the polygon attribute data for which the brush information is set is not set to the brush information. After setting the other polygon attribute data as the brush information (step 526), the process proceeds to step 518.

  Next, in step 518, one of the first polygon and the second polygon is selected as the parent polygon. Here, for example, the larger one of the first polygon and the second polygon may be selected as the parent polygon, or a circle inscribed in the polygon among the first polygon and the second polygon. The larger radius may be selected as the parent polygon. However, when the brush information of the polygon attribute data of one polygon is set to the polygon attribute data of the other polygon in step 526, the polygon of the polygon attribute data for which the brush information is originally set is set as the parent polygon. You may make it select.

  Next, the symbol attribute data of the symbol for drawing glasses is generated in step 514 and stored in the land register attribute data of the land register data (step 520). Note that the symbol type of the symbol attribute data generated here is the type of glasses, and the value indicating the polygon attribute data of the first polygon and the second polygon is set in the polygon attribute-corresponding polygon data. In the polygon attribute data, a value indicating the polygon attribute data of the polygon selected as the parent polygon in step 518 is set.

  Finally, glasses are set for the type of brush information in the polygon attribute data of the first polygon and the second polygon (step 522), and the process ends. That is, in this step 522, the fact that the type is the place of the brush information of the polygon attribute data of the first polygon and the second polygon, and the value indicating the symbol attribute data of the place symbol set in step 520 are stored. .

Now, details of the drawing method of the glasses symbol performed in step 514 will be described.
In FIG. 6a, when 601 is set as the first point and 602 is set as the second point, first, a small circle 611 centered on the first point and a small circle 612 centered on the second point are drawn. To do. The radius r of these two small circles is assumed to be the same as the radius of the small circle 401 drawn in step 506 of the glasses setting process.

  Next, a third vertex (vertex between two sides forming an apex angle) 631 of two isosceles triangles 621 and 622 having a base angle θ having the first point 601 and the second point 602 as the two vertices of the base. 632 is obtained. Next, out of the two obtained third vertices 631 and 632, the vertex 631 whose coordinates are located more south on the land register is selected. However, any one of the two obtained third vertices 631 and 632 may be selected here. Then, a circle 640 having a radius R centered on the selected vertex 631 is drawn. Here, the radius R is determined as R = L + d, where L is the length of the two equal sides of the isosceles triangles 621 and 622 determined previously. However, d is obtained as d = n × r (where n is a constant satisfying 0 <n <1), where r is the radius of the small circles 611 and 612.

  Then, a portion of the arc of the circle 640 excluding the arc 641 between the small circles 611 and 612 is erased to be a final glasses symbol. The arc 641 has, for example, an intersection point closer to the midpoint of a straight line connecting the first point 601 and the second point 602 of the two intersection points of the circle 640 and the small circle 611 as the first end point, the circle 640. Of the two intersections of the small circle 612 and the first point 601 and the second point 602, the intersection closest to the midpoint of the straight line is the second endpoint, and the circle 640 is the first endpoint and the second endpoint. A straight line that is cut and drawn so that the midpoint of the two arcs obtained by cutting passes from the center 631 of the circle 640 so as to pass through the midpoint of the straight line connecting the first point 601 and the second point 602. It is obtained by setting the upper arc as an arc 641 or the like.

Next, a fixed value may be used for the base angle θ of the two isosceles triangles 621 and 622 having the first point 601 and the second point 602 as the two vertices of the base. In this case, the base angle θ is set to By setting π / 3, equilateral triangles 621 and 622 may be used.
The base angle θ may be determined so that the base angle θ increases as the distance D increases as a function of the distance D between the first point 601 and the second point 602.
By doing so, as shown in FIG. 6b, even when the distance D between the first point 601 and the second point 602 is large, the arc 641 connecting the small circles 611 and 612 is as indicated by the broken line. It can suppress that it swells greatly.
The eyeglass setting process has been described above.

As described above, the figure processing unit 53 draws and superimposes the land map figure data from the polygon layer and the symbol layer, and the brush information display layer determined by the figure processing unit 53 in the order of description. The displayed image is displayed in the map display area 302 via the GUI control unit 51.
Hereinafter, drawing of the brush information display layer performed by the graphic processing unit 53 by determining the drawing contents will be described.
In accordance with the setting of the display mode of the brush information display layer set on the layer tool window 3033 as described above, the graphic processing unit 53 sets the brush information item designated by the user in the polygon attribute data for each polygon. The brush information display layer is drawn by reading from the brush information and drawing at the position of the center of gravity of the figure of the polygon.

  Here, the graphic processing unit 53 at this time, for the polygon for which the glasses are set in the type of the brush information of the polygon attribute data, the symbol attribute of the symbol attribute data indicated by the corresponding symbol attribute data described in the type Referring to the parent polygon attribute data, it is checked whether the polygon is set as the parent polygon. Only when the polygon is set as the parent polygon, the brush information item specified by the user is drawn at the position of the figure center of gravity of the polygon, and when it is not set as the parent polygon, the brush information is drawn. Do not draw the item.

  As a result, as shown in FIG. 3, only the polygon 3041 set as the parent polygon among the polygons of the two sections 3041 and 3042 constituting the glasses place in which the glasses place symbol 3043 is set is an item of the brush information. Is drawn and displayed, and the brush information item is not drawn and displayed on the polygon 3042 which is not set as the parent polygon. FIG. 3 shows the case where the user sets on the layer tool window 3033 as an item for displaying only the lot number among the items of the brush information.

Note that the graphic processing unit 53 controls the drawing of each layer including the brush information layer in the case of printing the cadastral map as well as the display, and prints the cadastral map image data for printing performed by the drawing output unit 55. Generate.
The embodiment of the present invention has been described above.
As described above, according to the present embodiment, the user can draw an appropriate glasses place symbol on the land register by simply designating two points on the land register that place the two small circles of the glasses place symbol. it can. In addition, according to the present embodiment, the brush information of one polygon can be inherited as the brush information of the other polygon only by setting the glasses ground symbol for the two polygons constituting the glasses. The setting and correction performed on the brush information of one polygon are automatically performed on the brush information of the other polygon. In addition, the brush information can be displayed only for one polygon only by setting the glasses symbol for the two polygons constituting the glasses.
