[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method and a system for displaying a group of graphics such as map information divided by a plurality of graphics indicating, for example, land blocks, and in particular, to change the color tone of each graphic in stages. The present invention relates to a graphic group display method, a graphic group display program, and a graphic group display system.
[0002]
[Prior art]
Conventionally, there are many graphic group display systems for creating and displaying a graphic group such as a map made up of various graphics, and some of these systems have a function of coloring a graphic. For example, as one having such a color painting function, there is a map creation system disclosed in Japanese Patent Laid-Open No. Hei 8-179688 in which a graphic display color is set and displayed based on certain attribute information. In this map creation system, a display color is set according to an attribute value of altitude for a range surrounded by contour lines on a map, and the display color is changed for each altitude and displayed on a monitor.
[0003]
[Problems to be solved by the invention]
In the system for setting the display color based on such constant attribute information, if each figure has constant attribute information related to the setting of the display color (or attribute information can be given to each figure), the monitor The display color of each figure above can be set. Here, when each of the figures to be displayed has a combination of those that have attribute information and those that do not have attribute information, color the figure whose attribute information is not clear in association with the figure whose attribute information is clear May be desired.
[0004]
For example, if a ruin is found at a certain place, the ruins are investigated at that place. In this ruin investigation, there is a possibility that the ruins exist around the place where the ruins were found. . Here, in such a ruin survey, it is useful to create a map that clearly shows the location where the ruins have already been discovered and the location where the ruins may exist. is there. Below, the case where the map creation system like a prior art is used for creation of this map is demonstrated.
[0005]
In general, in a map creation system, for example, a map is created using various graphic data such as a figure for each parcel (hereinafter also referred to as a “brush”) associated with the land owner and a railway figure. Is called. In such a map creation system, for the ranges (brushes) 100a to 100c where the ruins on the map 100A shown in FIG. 12A are found, the existence of the ruins is shown in FIG. 12B as attribute information. Coloring can be performed like a map 100B. Next, based on the colored brushes 100a to 100c, it is necessary to color the area (brush) where the ruins may exist, but for the brushes other than the brushes 100a to 100c, The attribute information related to the presence / absence is not clear and cannot be colored. In such a case, there is a possibility that it may be judged that there is no ruins in the uncolored range, and there is a possibility that the survey may be omitted. For this reason, it is necessary to clearly indicate the figure indicating the survey area with a certain width. However, it is difficult for the above map creation system to perform coloring with such a width. It was.
[0006]
Here, it is conceivable that the operator who operates this system judges the possibility of the existence of the ruins, and assigns attribute information to the target brush one by one, but the shape of the target brush is different and complicated. At the same time, since a map is created by a large number of adjacent brushes, it is very difficult to determine the possibility of the existence of a ruin for each brush.
[0007]

It is a table in which a G column 90d and a B column 90e are provided. Here, the tone levels of the present embodiment are set in five levels, and the higher the value, the higher the density. Note that the level is not necessarily limited to five levels as in the present embodiment.
[0023]
Next, the operation of the map display system of this embodiment will be described with reference to the flowcharts shown in FIGS. 9 to 11 and FIG.
[0024]
First, proximity processing in the control unit 1 will be described with reference to FIGS. In this embodiment, it is assumed that the ruins are found in the sections of figures (brushes) 1000 to 1002 with GIDs “1000” to “1002” shown in FIG. It is assumed that presence information has been input. The ruins presence information in this case is assumed to be “present” data in the ruins presence / absence column 70g in the brush attribute table 70 shown in FIG. 5 stored by the operator's input operation.
[0025]
First, the operator designates a desired color painting condition type (here, “archaeological site”) using the input unit 2 from among the various color painting condition types displayed on the display unit 3, for example. Subsequently, when the control unit 1 acquires the data of the color painting condition type designated by the operator (step ST1), the proximity processing function 1a uses the color painting condition type column 60b of the color painting condition table 60 shown in FIG. The data of the corresponding coloring condition type is searched from the inside, and the record to which the data belongs (here, the record of ID “1”) is acquired (step ST2). Then, the data of the name of the table (here, the brush attribute table 70 shown in FIG. 5) stored in the designation table column 60c of the record is read, and the record (ID “1” record) of the coloring condition table 60 is read. The record (table brush attribute table 70) corresponding to the conditions specified by the target column name column 60d, the comparison operator column 60e, and the target column value column 60f is searched, and the GID of the record is acquired (step ST3). ). In this case, the above condition is that the ruins presence / absence column 70g of the brush attribute table 70 is “present”, and the GIDs “1000”, “1001”, and “1002” of the brush attribute table 70 that meet this condition are acquired.
[0026]
Next, the proximity processing function 1a of the control unit 1 creates a brush information record of the graphic (graphics 1000 to 1002 shown in FIG. 12) related to the acquired GID in the brush information table 80 (step ST4). For example, the acquired GID (“1000”, “1001” and “1002”) data is stored in the GID column 80a of the brush information table 80 shown in FIG. In the ID column 80c and the display color level column 80d, the type (architecture) data designated by the operator in the above record (ID “1” record) of the color painting condition table 60, the data of the ID, and the level column value “5” Are stored respectively. The reason why the level column value is set to “5” in this case is to set the display color of the figure having the ruins to the maximum density, and the maximum density in this embodiment is the level column value “5”.
[0027]
Subsequently, the proximity processing function 1a of the control unit 1 evaluates the value of the proximity processing column 60h of the record (ID “1” record) in the coloring condition table 60 (step ST5). In this embodiment, since the value is “ON”, the proximity processing is performed on all the GID figures acquired in step ST3 as follows (step ST6), and the color specified by the operator The proximity process for the record (ID “1”) in the color painting condition table 60 relating to the painting condition type is terminated. If the value of the proximity processing column 60h is “OFF”, the processing for the record (ID “1”) is terminated without performing the proximity processing.
[0028]
Hereinafter, the proximity process in step ST6 shown in FIG. 9 will be described with reference to FIG. First, the proximity processing function 1a of the control unit 1 uses the map management information shown in FIG. 2 as circumscribing rectangular coordinates of the figure related to the GID (here, first GID “1000”) acquired in step ST3 shown in FIG. Obtained from the circumscribed rectangular coordinate array 40e of the table 40 (step ST6a). Thereafter, for each record in the map management information table 40, it is determined whether there is a circumscribed rectangle that overlaps the circumscribed rectangle specified by the circumscribed rectangle coordinates acquired in step ST6a (step ST6b). If there is no overlapping circumscribed rectangle, the process proceeds to step ST6i described later. If there is an overlapping circumscribed rectangle, the GID of the circumscribed rectangle is acquired from the GID column 40a (step ST6c), and the GID is shown in FIG. It is determined whether or not it exists in the indicated brush information table 80 (step ST6d).
[0029]
Subsequently, when there is no record related to the circumscribed rectangle GID in step ST64, the proximity processing function 1a of the control unit 1 adds the brush information record of the GID to the brush information table 80 (step ST6e). ), The process proceeds to step ST6h described later. In this step ST6e, for example, as shown in FIG. 6, the additional record includes “1003” in the GID column 80a, “Ruins” in the coloring condition type column 80b, “1” in the ID column 80c, “1” is stored in the display color level column 80d.
[0030]
If there is a record related to the circumscribed rectangle GID in step ST6e, it is determined whether or not the value of the display color level column 80d of the record of the GID is “4” or more (step ST6f). In such a case, “4” is used as a determination condition for the value of the level column. This is because the figure having the ruins and the figure having the possibility of existence can be discriminated by the color tone of the display color. The display color of the figure where the ruins exist is set to the maximum density, and the level lower than the maximum density level value of the display color with the color tone set to five levels (that is, the level value “4”) is set to the limit value. Because of that.
[0031]
Subsequently, when the value of the display color level column 80d is “4” or more in step ST6f, the proximity processing function 1a of the control unit 1 retains the value (that is, without counting up). It progresses to step ST6h mentioned later. If it is less than “4”, the value is counted up by 1 (step ST6g). Thereafter, the proximity processing function 1a of the control unit 1 determines whether or not the processing from steps ST6d to ST6g has been performed for all the overlapping circumscribed rectangle GIDs acquired in step ST6c (step ST6h). If not, the process returns to step ST6d and the above processing is performed for the next GID. In addition, if it has been performed, it is determined whether or not the processing from steps ST6a to ST6g has been performed for all the GIDs acquired in step ST3 shown in FIG. 9 (step ST6i). If the process is not performed, the process returns to step ST6a to perform the proximity process for the next GID. If the process is performed, the proximity process is terminated.
[0032]
By the processing of the proximity processing function 1a of the control unit 1 as described above, the brush information table 80 corresponding to the color painting condition type specified by the operator is created.
[0033]
Next, map display processing in the control unit 1 will be described with reference to FIG.
[0034]
First, the operator issues a map display process start instruction from the input unit 2. The map display processing start instruction in this case is, for example, designating a desired coloring condition type (here, “archaeological site”) on the screen of the display unit 3, and the type of the type to the control unit 1 with the start button on the screen Instructs the start of coloring.
[0035]
Here, in the system of the present embodiment, the operator can arbitrarily set the graphic display color for each color painting condition type. For this reason, when the operator wants to change the display color from the initial value, the operator designates a desired color painting condition type and display color using the input unit 2 from a display color setting screen (not shown) displayed on the display unit 3, for example. . Thus, when the display color is designated, the figure is painted with the designated color, and when the display color is not designated, the figure is painted with the initial color stored in the display color string 60g of the coloring condition table 60.
[0036]
Next, when receiving the above-described command for starting the map display process (step ST11), the control unit 1 determines whether or not the display color is designated by the operator using the display processing function 1b (step ST12). If a display color is specified, the process proceeds to step ST14, and an array of RGB values for each display color level corresponding to the specified display color data is created. If the display color is not designated, the display color data (“Gray” data of the record with ID “1”) stored in the display color string 60g of the coloring condition table 60 is read (step ST13). ). Then, the display color record corresponding to the value of the display color string 60g (in this embodiment, the five colors are the display color tone in this embodiment) is displayed in the display color table 90 shown in FIG. A search is performed from the column 90a, and each value is read from the R column 90c, the G column 90d, and the B column 90e of the record to create an array of RGB values for each display color level (step ST14). For example, the RGB value array data is temporarily stored in a memory.
[0037]
Subsequently, the display processing function 1b of the control unit 1 reads the record of the brush information table 80 shown in FIG. 6 (step ST15), and displays the XY coordinates of all the vertices of the graphic corresponding to the GID value in the record in FIG. Are obtained from the X coordinate sequence 50b and the Y coordinate sequence 50c of the vector information table 50 shown in FIG. Thereafter, the range of the figure specified by each vertex coordinate is filled with the array data of RGB values created in step ST14 corresponding to the display color level value of the record read in step ST15 (step ST17). Displayed on the display unit 3. Next, the display processing function 1b of the control unit 1 determines whether or not all the records in the brush information table 80 have been colored (step ST18). If there is an unprocessed record, the process returns to step ST15. When all the records are colored, the map display process is terminated.
[0038]
For example, the processing after step ST15 will be described with reference to the map 1000A shown in FIG. 12. First, the display processing function 1b of the control unit 1 uses the GID “1000” (the graphic 1000 shown in FIG. 12A) from the brush information table 80. ) And the XY coordinates of all vertices of GID “1000” are acquired from the vector information table 50. The range of the figure 1000 specified by each vertex coordinate is painted with the array data of RGB values corresponding to the display color level “5” as shown in FIG. Next, the records after the record of GID “1001” are colored in the same manner, and a map 1000B shown in FIG.
[0039]
Thereby, the display colors of the figures 1000 to 1001 in which the ruins have already been found are used as a reference, and the surrounding figures can also be displayed with a color change by changing the color tone. In such a case, an unexamined graphic is colored with a darker color as the circumscribed rectangle overlaps more frequently (graphics 1004 to 1006). For this reason, it is indicated that such a place is close to the figure where the ruins exist, and it becomes a judgment document that the existence possibility of the ruins is hidden, and it can be attributed to the investigation. It becomes possible.
[0040]
Here, the map 1000B shown in FIG. 12 (b) is not a map in which all the figures to be painted are colored in the result of the proximity processing and the map display processing described above in order to avoid the complexity of the diagram. Absent.
[0041]
As described above, according to the present embodiment, an unexcavated attribute whose attribute is not clear by a simple check of circumscribed rectangles using a figure (brush) whose attribute has already been determined has been determined. Simple color-coded display including graphics can be performed.
[0042]
Note that, as described above, when the display color setting is changed by the operator, the control unit 1 may change the data of the display color string 60g in the coloring condition table 60 to the designated display color. For example, when the color painting condition type “architecture” and the display color “red (red)” are designated, the display color string 60g of the record of ID “1” in the color painting condition table 60 is changed from “Gray” to “Red”. Is done. This display color setting change processing may be performed by the proximity processing function 1a of the control unit 1 before the creation of the brush information table 80 as described above. When the map display processing is performed, the control unit 1 The display processing function 1b may be used.
[0043]
In the present embodiment, the display colors are illustrated in five levels, but the present invention is not necessarily limited to this. Moreover, although the display color of the figure in which the ruins exist is set to the maximum density and the density of the display color is reduced as the possibility of the existence of the ruins decreases, the display color is not necessarily limited to this.
[0044]
Furthermore, when performing the overlap check, for example, a circumscribed circle connecting the vertices of the figure may be used instead of the circumscribed rectangle described above.
[0045]
Here, in this embodiment, it was illustrated as a graphic group display system used for excavation investigation of ruins, but it is not necessarily limited to this, for example, a place where a landslide disaster or river flooding occurred, unexploded bombs You may use this system when investigating dangerous places, such as excavated places.
[0046]
【The invention's effect】
According to the present invention, it is possible to easily and color-display a graphic with already clear attributes and a graphic with unclear attributes. Specifically, by determining the proximity based on a graphic with a clear attribute as a reference, a graphic with a clear attribute and a graphic with a clear attribute are selected from a group of graphic shapes. Each display color can be set, so that the operator can color-code each figure without giving the desired (color-coding) attribute information to the figure with unclear attributes. It becomes.
