Japanese Unexamined Patent Publication No. 2004-037540

Now, when creating a map formed by polygons (polygons) that represent sections, a plurality of polygons that represent a plurality of adjacent sections are drawn so that there are no gaps between them or overlap between polygons. Need to be done.
However, it is not always easy to draw polygons without gaps or overlaps in this way, and when creating a block map, an operator can create gaps in order to eliminate gaps and overlaps that have occurred after the block map is created. It was compelling to find the overlaps one by one and correct the shape of the polygons, and to elaborate and reduce the nerves.

  Therefore, an object of the present invention is to make it easier to eliminate gaps and overlaps between polygons that have occurred in a block map in which the blocks are represented by polygons.

  In order to achieve the above object, the present invention provides a map processing system that supports creation of a map formed by section polygons, which are polygons representing sections, by extracting gaps between section polygons on the map and A gap extracting means for presenting, a processing target gap setting means for setting a gap determined according to a user operation among the presented gaps as a processing target gap, and a section selected by a user adjacent to the area of the processing target gap The polygon includes a gap correcting means for correcting the polygon so as to include the region of the gap to be processed.

  According to such a map processing system, the user can correct the division polygon so that the gap is eliminated by a simple operation of simply selecting the division polygon that includes the presented gap area. . Therefore, the user can easily eliminate the gaps between the sectioned polygons that have been generated without performing the complicated work of finding the gaps themselves and manipulating the shape of the section polygons so that the gaps disappear. Can do.

  Here, in such a map processing system, when the gap correction means accepts selection of the type of operation to be performed on the area of the gap to be processed from the user and accepts selection of the type of first operation. When the section polygon selected by the user adjacent to the processing target gap area is corrected to include the processing target gap area and the selection of the second operation type is accepted, the processing target gap In this area, a polygon having the area may be newly generated as the partitioned polygon.

In this way, with respect to the gap caused by forgetting to place the division polygon, a new division polygon can be arranged in the area of the gap instead of correcting the other division polygon so as to fill the gap. It becomes like this.
Further, the map processing system such as these, in the gap extraction means, extracts gaps between the section polygons on the map, generates gap polygons that are polygons representing the areas of the extracted gaps, A list of gap polygon identifiers is presented to the user, and in the processing target gap setting means, a gap represented by the gap polygon whose identifier is selected on the list is set as a processing target gap, and in the gap correction means, The gap may be corrected using the gap polygon for which the identifier is selected. That is, for example, in the gap correction means, the selected division polygon is obtained by graphic calculation of the division polygon selected by the user adjacent to the processing target gap area and the gap polygon representing the processing target gap area. You may make it correct so that the area | region of the said process target clearance may be included.

By generating gap polygons for each gap in this way, each gap can be handled as a graphic object. As a result, the efficiency and diversification of various processes for eliminating the gap and elimination of the gap are eliminated. This makes it possible to simplify the user operation for this purpose.
In order to achieve the above object, the present invention provides a map processing system that supports creation of a map formed by section polygons, which are polygons representing sections, and extracts overlaps between section polygons on the map. A duplication extraction means to be presented, a processing target duplication setting means for setting a duplication determined according to a user operation among the presented duplications as a processing duplication, and a partition polygon including the processing duplication area The overlap correction for correcting the section polygons other than the one section polygon among the section polygons including the processing target overlapping area so that only one section polygon determined according to the user operation includes the processing target overlapping area. And means.

  According to such a map processing system, the user can perform the operation including the overlap area so that the overlap can be eliminated by the simple operation of determining the partition polygon including the overlap area that is presented. Other divided polygons other than the polygon can be corrected so as not to include the overlapping area. Therefore, the user can easily eliminate the duplication between the divided polygons that has occurred without performing the complicated work of searching for the duplicates themselves and manipulating the shape of the divided polygons so as to eliminate the duplicates. Can do.

  Here, in such a map processing system, when the duplication correcting unit accepts selection of the type of operation to be performed on the overlap area to be processed from the user and accepts selection of the first type of operation. , Among the section polygons including the processing target overlap area, so that only one section polygon determined according to the user operation includes the processing target overlap area. When a section polygon other than the one section polygon is corrected and selection of the second operation type is accepted, each section polygon including the processing target overlapping area is changed from the section polygon area to the processing target overlapping section. And a new polygon is generated as the section polygon for the overlapping area to be processed. It may be configured to. Alternatively, in the duplication correction unit, when the selection of the type of operation to be performed on the processing target duplication area is accepted from the user and the selection of the first operation type is accepted, the duplication correction area is included. Of the section polygons, only one section polygon determined according to the user operation includes the process target overlap area, and the section polygons other than the one section polygon among the section polygons including the process target overlap area are included. When the selection of the second operation type is accepted, each section polygon including the processing target overlapping area is corrected so that the processing target overlapping area is excluded from the section polygon area. You may comprise. Alternatively, in the duplication correction unit, when the selection of the type of operation to be performed on the processing target duplication area is accepted from the user and the selection of the first operation type is accepted, the duplication correction area is included. Of the section polygons, only one section polygon determined according to the user operation includes the process target overlap area, and the section polygons other than the one section polygon among the section polygons including the process target overlap area are included. When the selection of the second operation type is accepted, each section polygon including the processing target overlapping area may be deleted. Or you may make it provide in the duplication correction means which combined the function of the above duplication correction means suitably.

By doing in this way, various edits can be performed on the overlapping portion between the divided polygons or the related portion.
Further, the map processing system such as these, in the duplicate extraction means, extracts duplicates between the section polygons on the map, generates duplicate polygons that are polygons representing the extracted overlapping areas, A list of identifiers of overlapping polygons is presented to the user, and in the processing target duplication setting unit, the duplication represented by the overlapping polygons whose identifiers are selected on the list is set as processing target duplication, and in the duplication correction unit, You may make it correct duplication using the overlapping polygon by which the identifier was selected. That is, for example, in the duplication correction means, only one of the division polygons determined according to the user operation among the division polygons including the processing target overlapping area includes the processing target overlapping area. Of the divided polygons including the area, the divided polygons other than the one divided polygon may be corrected by a graphic operation of the divided polygon and the overlapping polygon representing the processing target overlap.

By generating overlapping polygons for each overlap in this way, each of the overlaps can be handled as a graphic object. As a result, the efficiency and diversification of various processes for eliminating the overlap and the elimination of the overlap are eliminated. This makes it possible to simplify the user operation for this purpose.

It comprises a section polygon correcting means for correcting the section polygon.

  According to such a map processing system, the user can sequentially eliminate gaps and overlaps related to the section polygons with an easy operation for each section polygon.

  As described above, according to the present invention, an operator can more easily eliminate gaps and overlaps between generated polygons in a block map in which the blocks are represented by polygons.

And polygon graphic data representing the shape and arrangement of the polygon. The attribute data stores the brush attribute information provided for each brush (section) included in the survey chart, and each brush attribute information corresponds to the polygon representing the corresponding brush on the survey chart. A polygon identifier, address information such as a corresponding lot number, and other attributes of the brush are described.

Hereinafter, the operation of the survey drawing map processing unit 5 of such a map processing system will be described.
Now, when the processing control unit 52 of the survey drawing map processing unit 5 starts the processing, first, the work window shown in FIG. 3A is displayed on the display device 1 via the GUI control unit 51.
As shown in the figure, the work window includes an upper command button row 301, a survey drawing map display area 302 provided on the left side, and a tool window group 303 provided on the right side. The investigation figure map display area 302 is an area for displaying the investigation figure map being processed. The figure processing unit 53 displays a map image or a survey represented by the lower figure data of the drawing data of the investigation figure map being processed. A graphical map is displayed. Here, the survey drawing map is composed of a polygon represented by the graphic data of the map data of the survey map being processed and a lot number represented by the brush attribute information of the polygon displayed in the polygon.

  The enlargement button, the reduction button, and the move button in the command button row 301 are buttons for enlarging, reducing, and scrolling the investigation figure map displayed in the investigation figure map display area 302. The open button in the command button row 301 is a button for selecting the drawing data of the investigation drawing to be processed from the drawing data stored in the drawing data storage unit 57, and save it. The button is a button for saving the raw map data of the survey chart being processed, and the setting button below is the map of the survey chart being processed by selecting the map image as the lower chart of the survey chart being processed. This is a button for setting as lower drawing data of the raw drawing data.

The tool window group 303 includes a drawing tool window 3031, an editing tool window 3032, an inspection tool window 3033, and an output tool window 3034.
Each tool window of the tool window group 303 is activated and displayed in the foreground by selecting a tab provided on the right side of each tool window. In addition, the tool window that receives the operation in the tool window can be switched to the active tool window displayed in the foreground. The operation of each tool window and command button is received by the processing control unit 52 via the GUI control unit 51, and the processing control unit 52 performs processing according to the received 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 drawing tool window 3031 is a tool window for drawing a polygon representing a brush on the investigation drawing map being processed and for setting brush attribute information such as a brush lot number represented by each polygon.
That is, if the brush boundary creation button 30311 is operated in the drawing tool window 3031, the processing control unit 52 causes the graphic processing unit 53 to move the figure on the survey drawing map display area 302 to the lower figure as shown in FIG. The input of the border line 310 of the brush as shown in FIG. If the plotting execution button 30312 is operated in the drawing tool window 3031, the graphic processing unit 53 corresponds to each area surrounded by the input boundary line 310 as shown in FIG. A polygon 320 having a corresponding region as a polygon inner region is generated, and the generated polygon data of each polygon 320 is stored in the graphic data of the drawing data being processed.

  Further, the processing control unit 52, when one polygon is selected on the survey drawing map display area 302, if the large / small button 30313, the lot number button 30314, etc. are operated in the drawing tool window 3031, The attribute processing unit 54 accepts input of brush attribute information such as large / small letters and lot numbers, and uses the received brush attribute information as the brush attribute information of the brush corresponding to the selected polygon. It is stored in the attribute data of the drawing data.

  Next, the editing tool window 3032 allows the graphic processing unit 53 to edit the shape and position of the polygon generated as described above when the processing control unit 52 receives the editing operation of the user, and corresponds to each polygon. It is a tool window for making the attribute process part 54 edit the brush attribute information of a brush to perform.

  In addition, the output tool window 3034 is a printing device in a form according to the user setting of the survey diagram map that the process control unit 52 receives the user's survey diagram map output operation and represents the map data being processed. 3 is a tool window for causing the drawing output processing unit 55 to perform printing in step 3.

The remaining inspection tool window 3033 is a tool window for inspecting and eliminating gaps and overlaps between polygons generated as described above.
Hereinafter, an operation for inspecting and eliminating gaps and overlaps between polygons using the inspection tool window 3033 will be described.
As shown in FIG. 4 a, the inspection tool window 3033 is provided with a gap inspection button 41 and a duplicate inspection button 42.
Then, when the gap inspection button 41 is operated by the user, the processing control unit 52 extracts a gap between polygons on the survey drawing map, that is, an area where no single polygon is arranged in the graphic processing unit 53. Then, generation of a polygon as a gap area polygon using each extracted area as an in-polygon area is performed. That is, for example, as shown in FIG. 4 b 1, when a plurality of polygons 410 are arranged on the survey drawing map, corresponding to the two regions that are not the regions of any polygon 410, as shown in FIG. Thus, two gap area polygons 411 are generated. Here, if the graphic processing unit 53 generates the gap region polygons in this way, the graphic processing unit 53 generates the inspection object data shown in FIG. 2B corresponding to each generated gap region polygon. The corresponding gap area polygon data is set and held in the memory 56.

  As shown in the figure, the inspection object data includes an inspection object identifier, an inspection object type, a processed flag, polygon graphic data, and processing history data. In the inspection object data corresponding to the generated gap area polygon, an identifier for uniquely identifying the gap area polygon corresponding to the inspection object identifier is set, and the type information indicating the gap area polygon is set as the inspection object type. The unprocessed flag is set for the processed flag, and graphic data representing the shape and arrangement of the corresponding gap area polygon is set for the polygon graphic data.

  When the gap area polygon 411 is generated in this manner, the process control unit 52 displays the generated gap area polygon 411 on the graphic processing unit 53 as shown in FIG. 4a. On the survey drawing map of the area 302, the specific display color is displayed so as to be distinguishable from other polygons.

Further, when the gap area polygon 411 is generated, the processing control unit 52 displays a gap processing window 420 on the display device 1 via the GUI control unit 51, as shown in FIG.
A list of gap area polygon identifiers in which the inspection object data is held in the memory 56 is displayed in the gap list area 421 provided in the gap processing window 420. The gap area polygon in which the inspection object data is held in the memory 56 is an inspection object in which type information representing the gap area polygon is set as the inspection object type in the inspection object data held in the memory 56. It is obtained as a gap area polygon represented by the data. In addition to the gap list area 421, the gap processing window 420 is provided with a selection button 422, an edit button 423, an automatic adjustment button 424, a return button 425, and an end button 426.

  Then, when the selection button 422 on the gap processing window 420 is operated in a state where any gap area polygon is selected in the gap list area 421, the processing control unit 52 causes the figure processing unit 53 to display FIG. As shown in FIG. 5, the display of the survey diagram map is moved so that the selected gap region polygon 501 is positioned at the center of the survey diagram map display area 302. Further, the graphic processing unit 53 displays the selected gap area polygon 501 in a shaded manner. At this time, it is also preferable to enlarge and display the periphery of the gap area polygon 501 as illustrated.

  In the state shown in FIG. 5a, if the user selects a polygon on the survey drawing and operates the edit button 423 of the gap processing window 420, the processing control unit 52 is selected by the graphic processing unit 53. Edit the selected polygon. In addition, in the editing of the polygon, the graphic processing unit 53 updates the polygon display in the graphic data of the drawing data in addition to updating the display of the polygon in the survey drawing drawing display area 302 according to the editing content. Updates are made accordingly. Further, when the editing is completed, the processing control unit 52 stores the contents of the editing performed in the processing history data of the inspection object data of the selected gap region polygon 501. Further, if the gap corresponding to the selected gap area polygon 501 has disappeared by the editing, the process control unit 52 sets the processed flag of the inspection object data to processed. Further, the processing control unit 52 cancels the selected state of the selected gap region polygon 501 when editing is completed.

  Here, for the gap area polygons for which the processed flag is set in the processed flag of the corresponding inspection object data, the gap list area 421 is displayed in a form that can identify that the gap area polygon has been processed. In addition, a gap area polygon for which “processed” is set in the processed flag of the corresponding inspection object data is displayed in the survey graphic element unless the gap area polygon is shaded as described above when the gap area polygon is in the selected state. Do not display in the figure display area 302.

Next, if the user operates the automatic adjustment button 424 of the gap processing window 420 in the state of FIG. 5A, the processing control unit 52 includes a merge button 511 and a plotting button 512 as shown in FIG. 5B. The process selection window 510 is displayed on the display device 1 via the GUI control unit 51.
Then, as shown in FIG. 6a1, if the merge button 511 of the process selection window 510 is operated, as shown in FIG. 6a2, a message prompting the user to select a polygon that merges the areas of the gap area polygon 501 in the selected state. If the polygon 502 adjacent to the selected gap area polygon 501 is selected as a polygon to be merged with the area of the selected gap area polygon 501, the graphic processing unit 53 displays in FIG. 6 a 3. As shown, the selected polygon 502 is corrected to a polygon whose region is a region where the gap region polygon 501 in the selected state and the selected polygon 502 are combined. Here, a polygon obtained by combining the gap area polygon 501 and the selected polygon 502 can be obtained by a graphic operation by logical OR of the gap area polygon 501 and the polygon 502.

In addition, in the correction of the polygon 502, the graphic processing unit 53 updates the display of the polygon 502 in the survey drawing map display area 302 according to the editing content, and also polygon data of the polygon 502 in the graphic data of the drawing data. Update according to the edited contents of.
When the correction of the polygon 502 is completed, the editing contents of each polygon performed after the operation of the merge button 511 is stored in the processing history data of the inspection object data of the selected gap area polygon 501. Then, the processed flag of the inspection object data is set to processed. Also, the selected state of the gap area polygon 501 is canceled.

  As a result of the registration and the cancellation of the selected state, the display of the gap area polygon 501 in the gap list area 421 in the gap processing window 420 can identify that the gap area polygon 501 has been processed (FIG. In this case, the display changes to a display with a processed character string added), and the gap region polygon 501 is not displayed in the survey drawing map display area 302.

  Next, as shown in FIG. 6b1, if the image selection button 512 of the process selection window 510 displayed in response to the user's operation of the automatic adjustment button 424 of the gap processing window 420 is operated, the process control is performed. The unit 52 causes the graphic processing unit 53 to generate a new polygon 503 in which the region of the gap region polygon 501 in the selected state is the in-polygon region, as shown in FIG. 6b2. In addition, in the generation of the polygon 503, the graphic processing unit 53 newly displays the polygon 503 in the survey drawing map display area 302, generates new polygon data of the polygon 503, and enters the graphic data of the drawing data. Also stores.

  Then, when the generation of the polygon 503 is completed, the contents of the investigation figure map editing performed after the draw button 512 operation is used as the processing history data of the inspection object data of the selected gap area polygon 501. In addition to storing, the processed flag of the inspection object data is set to processed. Also, the selected state of the gap area polygon 501 is canceled.

  Next, the processing control unit 52, when the gap region polygon registered as processed in the processed flag of the corresponding inspection object data is in a selected state and is shaded in the center of the survey chart display area, The return button 425 of the gap processing window 420 is made operable by the user, and the display of the character “return” on the return button 425 is changed from gray display to normal black display. When the return button 425 is operated, the process history of the inspection object data of the gap area polygon in the selected state is referred to, and the edit is performed when the gap area polygon indicated by the process history is in the selected state. The polygon that has been edited is returned to the state where the editing has not been performed, the processed flag of the inspection object data of the gap area polygon in the selected state is changed to unprocessed, and the processing history of the inspection object data is deleted. Thus, the gap area polygon and the polygon edited in relation to the gap area polygon are restored to the state at the time when the gap area polygon in the selected state is generated.

  Further, when the end button 426 of the gap processing window 420 is operated, the process control unit 52 deletes the inspection object data held in the memory 56 and closes the gap processing window 420.

  Next, as shown in FIG. 7a, when the duplication inspection button 42 of the inspection tool window 3033 is operated, the processing control unit 52 causes the graphic processing unit 53 to display the overlapping region of the polygon on the survey drawing. Extraction and generation of polygons as overlapping area polygons with each extracted overlapping area as a polygonal area are performed.

  That is, for example, as shown in FIG. 7b1, when a plurality of polygons 710 are arranged on the survey chart, two overlapping areas are shown in FIG. 7b2 corresponding to the two overlapping areas that exist. A polygon 711 is generated. The overlapping area is extracted for each combination of polygons using the overlapping area as an in-polygon area. That is, when a part of the overlapping part between the polygon A and the polygon B overlaps with the polygon C, the overlapping part between the polygon A and the polygon B overlaps only with the polygon A and the polygon B. Two overlapping areas of the overlapping area and the overlapping area overlapping polygon A, polygon B, and polygon C are extracted, and two overlapping area polygons are generated with each of the two overlapping areas as an in-polygon area. The

  Here, if the graphic processing unit 53 generates the overlapping area polygons in this way, it generates the inspection object data shown in FIG. 2B corresponding to each generated overlapping area polygon, and corresponds to the generated inspection object data. The overlapping area polygon data to be set is set and stored in the memory 56. Here, in the generated inspection object data of the overlapping area polygon, an identifier for uniquely identifying the corresponding overlapping area polygon is set as the inspection object identifier, and type information representing the overlapping area polygon is set as the inspection object type. Then, unprocessed is set in the processed flag, and graphic data representing the shape and arrangement of the corresponding overlapping area polygon is set in the polygon graphic data.

  If the overlapping region polygon 711 is generated in this way, the processing control unit 52 displays the generated overlapping region polygon 711 on the graphic processing unit 53 as shown in FIG. 7a. On the survey drawing map of the area 302, the specific display color is displayed so as to be distinguishable from other polygons.

Further, when the overlapping area polygon 711 is generated, the processing control unit 52 displays the overlapping processing window 720 on the display device 1 via the GUI control unit 51 as shown in FIG.
Then, a list of identifiers of overlapping area polygons in which the inspection object data is held in the memory 56 is displayed in the overlapping list area 721 provided in the overlapping processing window 720. Note that the overlapping area polygon in which the inspection object data is stored in the memory 56 is an inspection object in which type information representing the overlapping area polygon is set as the inspection object type in the inspection object data stored in the memory 56. It is obtained as an overlapping area polygon represented by the data. In addition to the overlap list area 721, the overlap processing window 720 is provided with a selection button 722, an edit button 723, an automatic adjustment button 724, a return button 725, and an end button 726.

  Then, when the selection button 722 on the overlap processing window 720 is operated in a state where any overlap region polygon is selected in the overlap list area 721, the processing control unit 52, as shown in FIG. The processing unit 53 moves the display of the survey figure map so that the selected overlapping region polygon 801 is positioned at the center of the survey figure map display area 302. In addition, the selected overlapping area polygon 801 is displayed in a shaded manner on the graphic processing unit 53. At this time, it is also preferable to enlarge and display the periphery of the overlapping area polygon 801 as shown in the figure.

  Then, in this state of FIG. 8 a, if the user selects a polygon on the survey chart and operates the edit button 723 of the duplication processing window 720, the processing control unit 52 is selected by the graphic processing unit 53. Edit the selected polygon. Further, when the editing is completed, the processing control unit 52 stores the contents of the editing performed in the processing history data of the inspection object data of the selected overlapping area polygon 801. Further, if the overlap corresponding to the selected overlapping area polygon 801 has disappeared by the editing, the processing control unit 52 sets the processed flag of the inspection object data to processed. Further, when the editing is completed, the processing control unit 52 cancels the selected state of the selected overlapping area polygon 801.

  Here, the overlapped area polygons for which the processed flag is set in the processed flag of the corresponding inspection object data are displayed in a form that can identify that the overlapped area polygon has been processed in the overlapped list area 721. In addition, the overlapping area polygons for which processing has been set in the processing flag of the corresponding inspection object data are not shown in the figure except for the case where the overlapping area polygon is displayed in the shaded state as described above when the overlapping area polygon is in the selected state. Do not display in the figure display area 302.

Next, if the user operates the automatic adjustment button 724 of the overlap processing window 720 in the state of FIG. 8a, the processing control unit 52, as shown in FIG. 8b, the merge button 811, the plotting button 812, and the related A process selection window 810 having a brush figure deletion button 813 and an overlapping part deletion button 814 is displayed on the display device 1 via the GUI control unit 51.
Then, as shown in FIG. 9a1, if the merge button 811 of the process selection window 810 is operated, as shown in FIG. 9a2, a polygon that exclusively includes the area of the overlapping area polygon 801 in the selected state is selected. If a prompt message 820 is displayed and one of the polygons 802 and 803 including the overlapping region polygon 801 in the selected state is selected as a polygon to merge the regions of the overlapping region polygon 801 in the selected state, For example, as shown in FIG. 9a3, the graphic processing unit 53 sets the polygon 803 excluding the selected polygon 802 out of the polygons 802 and 803 including the overlapping region polygon 801 in the selected state to the selected state in the polygon inner region. Correction is made so as not to include an area of a certain overlapping area polygon 801. Here, a polygon obtained by correcting the polygon 803 in this way can be obtained by a graphic operation based on an exclusive logical OR of the overlapping area polygon 801 and the polygon 803. The overlapping relationship between the polygons 802 and 803 is as shown in FIG. 7b1.

The processing history data of the object data is stored, and the processed flag of the inspection object data is set to processed. Also, the selection state of the overlapping area polygon 801 is canceled.

  Next, as shown in FIG. 10a1, if the related brush figure deletion button 813 of the process selection window 810 displayed in response to the user's operation of the automatic adjustment button 724 of the overlap processing window 720 is operated, the process control unit 52, causes the graphic processing unit 53 to delete all the polygons 802 and 803 having the overlapping region polygon 801 in the selected state as the in-polygon region as shown in FIG. 10a2.

The graphic processing unit 53 deletes the display of the polygons 802 and 803 in the survey drawing map display area 302 and deletes the polygon data of the polygon data of the polygons 802 and 803 when deleting the polygons 802 and 803. Also delete from the data.
Then, when the deletion of the polygons 802 and 803 is finished, the contents of the investigation drawing drawing edited after the operation of the related brush figure deletion button 813 is processed as the inspection object data of the selected overlapping area polygon 801. While being stored in the history data, the processed flag of the inspection object data is set to processed. Also, the selection state of the overlapping area polygon 801 is canceled.

  Next, as shown in FIG. 10b1, if the overlapping part deletion button 814 of the processing selection window 810 displayed in response to the user's operation of the automatic adjustment button 724 of the overlapping processing window 720 is operated, the process control is performed. As shown in FIG. 10b2, the unit 52 sends all of the polygons 802 and 803 including the overlapping region polygon 801 in the selected state to the region of the overlapping region polygon 801 in the selected state in the region within the polygon. It is corrected so that it does not include.

  In addition, in the modification of the polygons 802 and 803, the graphics processing unit 53 updates the display of the polygons 802 and 803 in the survey diagram map display area 302 according to the edited contents, and also in the graphics data of the diagram data. Updating according to the editing content of the polygon data of the polygons 802 and 803 is also performed.

  When the correction of the polygons 802 and 803 is completed, the processing history of the inspection object data of the selected overlapping area polygon 801 is used as the contents of the editing of the survey drawing performed after the operation of deleting the overlapping parts 814. The data is stored in the data, and the processed flag of the inspection object data is set to processed. Also, the selection state of the overlapping area polygon 801 is canceled.

  Here, by using the image selection button 812 and the overlapped part deletion button 814 of the process selection window 810 displayed in response to the operation of the automatic adjustment button 724 of the overlap process window 720 as described above, the user can After creating another polygon 1002 in one polygon 1001 as in 10c1, the following editing can be performed. That is, the image formation button 812 creates two nested polygons 1001 and 1003 having no overlapping portion as shown in FIG. 10c2, or the overlapping portion erasing button 814 creates a perforated polygon 1001 as shown in FIG. 10c3. Can be.

  Now, next, the processing control unit 52 is in the processing flag of the corresponding inspection object data, when the overlapping area polygon registered processing has been selected and is displayed in the center of the survey chart display area Further, the return button 725 of the overlap processing window 720 is made operable by the user, and the display of the character “return” on the return button 725 is changed from the gray display shown to the normal black display. When the return button 725 is operated, the processing history of the inspection object data of the overlapping area polygon in the selected state is referred to, and editing is performed when the overlapping area polygon indicated by the processing history is in the selected state. The polygon that has been edited is returned to the state in which the editing has not been performed, the processed flag of the inspection object data of the overlapping area polygon in the selected state is changed to unprocessed, and the processing history of the inspection object data is deleted. As a result, the overlapping area polygon and the edited polygon related to the overlapping area polygon are restored to the state at the time when the overlapping area polygon in the selected state is generated.

  In addition, when the end button 726 of the duplication processing window 720 is operated, the processing control unit 52 deletes the inspection object data held in the memory 56 and closes the duplication processing window 720.
