Description

  The present invention relates to a map information system in which arbitrary data is linked to map information.

  In recent years, digitized map data such as GIS (Geographic Information System) has been used to manage an enormous amount of information by combining various other information. Specifically, for example, in a civil engineering company, a huge amount of information can be visualized by linking a design drawing or survey report, etc., for each construction with the position on the map corresponding to the construction location of the construction. It can be managed easily (geographically). Or, for example, in local governments, etc., it is used for management of water supply and sewerage systems, road management, and design drawings and reports received from civil engineering-related companies in charge of construction work.

For example, a technique described in Patent Document 1 has been proposed for associating arbitrary data with the map information.
In the prior art described in Patent Document 1, a table for linking document data and map data is prepared so that it can be flexibly accessed from a document system or a map data system.

  Patent Document 2 discloses a method of changing the display content of a map according to an access level. That is, a technology is disclosed in which a map including detailed information is presented to a viewer with a high access level, and a map with information omitted is presented to a viewer with a low access level.

Alternatively, Patent Document 3 discloses a method for managing layer information managed in graphic data with layer information in a column (column only for layer information) different from graphic data. Thus, for example, when extracting drawing data having one meaning in a specific layer such as a road or a station without extracting information on a private house or sea, the specific layer information using the specified layer information as a key Therefore, since unnecessary graphic data (graphic data other than the target layer) is not transferred, the transfer speed can be increased by reducing the data transfer amount.
JP 2003-167919 A JP 2003-99433 A Japanese Patent Laid-Open No. 10-3486

  Here, in general, the electronic map in the GIS has a layer structure, and a plurality of types of map data are combined and displayed as one map in a superimposed form. For example, as an example, a lottery map and house map are used as the base map data, and then any of various layers such as waterworks, sewerage, gas pipes, electric wires, telephone lines, rivers, land readjustments, fixed assets, disaster prevention information, etc. By superimposing one or more, map information can be created and displayed flexibly (that is, a layer means various types of map data by purpose). In a map information system having such a layer structure, for example, information on water pipes and valve plugs (object data) used in waterworks, etc., design CAD drawings, reports, photographs, etc. data received from civil engineering companies ( (Delivery data) and map data are considered to be used in cooperation. For example, any symbol (icon, etc.) linked to each delivery data at a corresponding position on the map corresponding to each delivery data location (construction location, etc.), but not limited to polygons, circles, characters, etc. When the user clicks a desired symbol, the contents of delivery data linked to the symbol are displayed. Or each object data (for example, water pipe etc.) is displayed on the applicable position on a map.

  In the electronic map having the layer structure, when the electronic map is corrected or upgraded, only the layer to be changed needs to be replaced without changing the entire electronic map. However, as a result of replacing the layers, for example, because there were added houses and roads that did not exist before the change, the display of the symbols and objects overlapped with the houses and roads, etc. The problem arises that it becomes difficult to understand (for example, it is mistaken for other construction data).

  In the above prior art, such a problem associated with layer replacement is not considered at all. Therefore, when the above problem occurs in the related art, it is conceivable that an operator or the like responds manually, for example. That is, for example, the operator or the like displays the electronic map after switching the layers, finds a place that is difficult to see / understand visually, and manually moves, for example, the position of an icon or the like in this place. In other words, the burden on the operator is large, and it is difficult to see / understand, so there are cases in which a portion to be changed is overlooked.

  It is an object of the present invention to reduce the burden on the operator and the like by automatically performing such movement and highlighting when the display of symbols, objects, etc. becomes difficult to understand due to changing the map information layer It is to provide a map information system, its program, etc.

  The map information system of the present invention is a map information system in which arbitrary various data is linked with map information, and the various data is arranged and displayed on a map, and any of a plurality of layers constituting the map information is displayed. When the layers are replaced, the different areas are detected by comparing the layers before and after the replacement, and the different area detecting means for detecting the data arranged on the different areas among the various data, and the different areas And an appropriate arrangement processing means for moving the arrangement position of the data detected by the equal detection means on the map out of the different area.

  In the above map information system, by comparing the layers before and after replacement and detecting a different area, a part where there is a possibility that a new configuration is added (addition of a house, a road, etc.) in the map after the change is detected. . Then, the data arranged on the different area is detected, and moved outside the different area, or highlighted, for example. In particular, when the data arranged on the map is a symbol or the like corresponding to the delivery data, the symbol is moved. For example, when the data is object data such as water pipe piping data, this is highlighted. .

  According to the map information system, the program, etc. of the present invention, when the display of symbols, objects, etc. becomes difficult to understand due to the change of the layer of map information, the symbols, objects, etc., which are difficult to understand are automatically displayed. Thus, it is possible to significantly reduce the work load on the operator and the like by performing the determination and performing the movement and highlighting.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a configuration diagram of the map information system of this example.
The illustrated map information system 10 includes a data input / output device 20, a data arrangement processing unit 30, a map layer replacement processing unit 40, a different area detection processing unit 50, a delivery data appropriate arrangement processing unit 60, a display processing unit 70, and a delivery data DB. (Database) 80, object information DB90, map information DB100, and map / object management DB110.

  The functions and processes of the functional units such as the data arrangement processing unit 30, the map layer replacement processing unit 40, the different area detection processing unit 50, the delivery data appropriate arrangement processing unit 60, the display processing unit 70, and the like are related to the map information system. 10 is realized by reading / executing a predetermined application program stored in a storage device (hard disk or the like: not shown here) by a CPU or the like (not shown here).

  As explained somewhat in the prior art, construction contractors (civil engineering, construction-related companies, etc.) have delivered data groups (electronic data) consisting of multiple types of data such as design drawings (CAD data), reports (word processing data), and digital photographs. ) To a local government or the like in a form stored in a portable recording medium such as a CD-R or online. In addition, object data that is data indicating the piping status of a water pipe or the like is created.

  The data input / output device 20 is configured to input these delivery data and object data to the map information system 10. For example, when the delivery data is stored in a CD-R and delivered, the data input / output device 20 Reference numeral 20 denotes a CD-R reader. For example, when delivery data is delivered online, the data input / output device 20 is a network connection device. Alternatively, the data input / output device 20 is a display device such as a display, an electronic mail transmission / reception device, or the like.

  The data arrangement processing unit 30 and the map layer replacement processing unit 40 are configured to exist conventionally. In other words, as described above, conventionally, delivery data and the like are linked with map information, and symbols such as icons and object data are arranged at corresponding positions on the electronic map. The processing unit 30 is configured to manually perform these arrangements by an operator, for example. That is, the electronic map stored in the map information DB 100 is displayed on a display or the like, and the input delivery data list is displayed, and a desired symbol is assigned to each delivery data, and this symbol is assigned to the desired map on the electronic map. It is arranged at a position (however, at or near the above-mentioned corresponding position). The relevant position is, for example, the location of a building when certain delivery data relates to the construction of the building.

  The input delivery data is stored in the delivery data DB 80. The object data is also stored in the object information DB 90 when it is arranged on a map such as a water pipe. The location information of the delivery data and object data on the map is stored in the map / object management DB 110.

  Then, when it becomes necessary to replace a layer with map information (for reasons such as change, correction, version upgrade, etc.), the map layer replacement processing unit 40 replaces the replacement target layer.

  Conventionally, the electronic map itself, the symbol, the object, and the like are displayed using the electronic map after the layer replacement, and the operator or the like visually determines and moves the symbol. Then, a different area is detected by the different area detection processing unit 50 and a symbol or an object on the different area is detected. Based on the detection result, the delivery data appropriate arrangement processing unit 60 assigns the symbol to an appropriate arrangement location. The display processing unit 70 highlights the object data. Details will be described below with reference to FIG.

  The map information DB 100 stores a layer table 210 and a map configuration table 220 as shown in FIGS. 3A and 3B, for example, together with each layer information. The map / object management DB 110 stores arrangement position information on the map, that is, the delivery data table 230, the object data table 240, and the delivery / object arrangement table 260 shown in FIGS. 3C to 3E, for example. The

FIG. 2 shows a flowchart of processing by the map information system 10.
In the figure, an operator or the like arranges object data and delivery data on a map (step S11), as described above, is substantially the same as the conventional process. For example, first, various maps stored in the map information DB 100 are used. An operator or the like selects desired map information from the information and displays it. This map information is managed by, for example, the layer table 210 and the map configuration table 220 shown in FIGS. The layer table 210 illustrated in FIG. 3A includes data items such as a layer ID 211, a layer type 212, a layer storage destination 213, a layer registration time 214, and the like. The map configuration table 220 shown in FIG. 3B includes data items such as a map ID 221, each configuration layer (1, 2,...) 222 and a map registration time 223.

  As already described in the related art, in GIS and the like, map information is composed of a plurality of layers, and an arbitrary plurality of layers are superimposed and displayed. That is, the layer is map data for each purpose, which can be said to be partial information (part of the map information) constituting the map information. The layer table 210 is a table for managing each layer, the layer ID 211 is the identification number of the layer, the layer type 212 is the type of the layer (road, feature, house map, etc.), and the layer storage destination 213 is The storage address and file name of the layer, etc., and the layer registration time 214 is the date of registration of the layer. Each map is created by combining these layers, and the map configuration table 220 stores an identification number (map ID 221) of the created map and a layer ID of each layer constituting the map.

  When the operator selects an arbitrary map as described above, each layer constituting the map is obtained from the map configuration table 220 using the map ID of the selected map, and further, the file of each layer and the like are obtained from the layer table 210. A map is displayed by acquiring and referring to.

  In the process of step S11, on the map displayed in this way, an operator or the like can construct any object data (for example, new water pipe piping data) or newly delivered from, for example, a civil engineering company. By designating the relevant position (pipe position, construction site, etc.) on the map by operating the keyboard, mouse, etc. for the above-mentioned delivery data, which is data such as design CAD diagrams, reports, photographs, etc., these objects Link data and delivery data with map information. As a result of this association, for example, a delivery data table 230, an object data table 240, and a delivery / object arrangement table 260 shown in FIGS. 3C to 3E are created.

  In the delivery data table 230 shown in FIG. 3C, the above-mentioned operator or the like designates various data related to delivery data such as delivery data ID 231, delivery data type 232, delivery data storage destination 233, delivery data registration time 234 on the map. The position coordinates (X coordinate 235, Y coordinate 236) are associated with each other. Similarly, in the object data table 240 shown in FIG. 3D, the above-mentioned operator or the like includes various data related to object data such as object data ID 241, object type 242, pipe type 243, pipe diameter 244, usage 245, registration time 246, and the like. Position coordinates (start point X coordinate 247, start point Y coordinate 248, end point X coordinate 249, end point Y coordinate 250) designated on the map are associated with each other.

  Further, a delivery / object arrangement table 260 as shown in FIG. In the illustrated table 260, the data ID 261 is the delivery data ID or object data ID of the delivery data or object data that has been linked, and the type 262 is the delivery data type or object type. Map ID263 is map ID of the map of a cooperation destination. The start point X coordinate 264, the start point Y coordinate 265, the end point X coordinate 266, and the end point Y coordinate 267 are the specified position coordinates on the map of the map ID 263, and the administrator 268 can set each delivery data ID or object data. The name and employee number of the person in charge of management / preparation.

Returning again to FIG.
The processing after step S12 is not continued after the linkage with the map information is performed by the processing of step S11. Of course, if it is necessary to replace the map layer when registering new delivery data, etc., it may be continued as shown in the figure, but in general, the processing in step S11 and the processing in and after step S12 are the same. Often done separately.

  As described above, the process of step S12 is substantially the same as the conventional process. For example, at least one of the plurality of layers constituting the map information needs to be corrected or changed (version upgrade, etc.). When this occurs, the operator or the like designates the replacement source layer (for example, the old version) and the replacement destination layer (for example, the new version), and replaces the layers (step S12). For example, when there is a version upgrade of the layer ID = Layer 1 shown in FIG. 3A, a new layer ID = Layer 1 ′ is given to this upgraded version layer and additionally registered in the layer table 210, and the map All Layer1 in the configuration table 220 are changed to Layer1 ′. In this example, the display content of the map with map ID = map1 changes in the example of FIG. 3B, but the display content of the map with map ID = map2 does not change.

  Thereafter, a message asking whether or not to use the different area detection function is displayed on the display, and the operator or the like is allowed to input YES / NO. If the operator or the like chooses not to use the different area detection function (step S13, NO), the process proceeds to the process of step S23 as it is, and the map after the layer change is displayed and confirmed by the operator or the like. The process ends. Of course, if necessary, symbols may be manually changed by an operator or the like as usual.

  On the other hand, when the different area detection function is used (step S13, YES), first, the layers before and after replacement are compared (for example, the old version and the new version are compared), and all the different areas are extracted. (Step S14). In the above example, the layer having the layer ID = Layer 1 and the layer having the layer ID = Layer 1 ′ are compared, and all portions where the data do not match (that is, different regions) are detected. The different area may be the non-matching part itself, or may be a whole area around the non-matching part (a circular area having a preset size or the like). As a method for extracting a different area, for example, a technique described in Japanese Patent Laid-Open No. 2001-175849 may be used, or another conventional technique may be used.

  Subsequently, all the delivery data or object data arranged in the detected different area is detected (step S15). As described with reference to FIGS. 3C, 3D, and 3E, the arrangement coordinates of the delivery data and the object data on the map are recorded in the tables. The delivery data and object data arranged in can be easily searched.

  Subsequently, referring to the delivery / object arrangement table 260 in FIG. 3E, among the object data detected in step S15, only the object data for which the operator is the manager is stored in the step. It is set as a processing target of processing after S18 (step S17). With this function, only the object data that the operator is in charge of as an administrator can be processed, so that the correction work can be performed efficiently. If the operator or the like is not the object data manager (not in the table 260 manager 268) (NO in step S16), the process in step S17 is not performed, and the object data detected in step S15 or the like. Are all subject to processing in and after step S18.

  Then, it is determined whether or not to use the automatic arrangement function for the delivery data among the data to be processed (each delivery data and each object data) (step S18). This allows, for example, an operator to determine / select whether to use the automatic placement function. If the automatic placement function is used (step S18, YES), a process for shifting symbols (icons, etc.) placed on the map out of the different areas for each delivery data to be processed. Perform (step S19). Any method can be used for shifting, but for example, a method of moving in the shortest direction out of the different area can be considered. Then, an inquiry is made to the operator as to whether or not the position after movement is acceptable. If the operator is dissatisfied with the automatically arranged position (step S20, NO), the operator manually moves the symbol position to a desired position (step S21).

  When the new position of the symbol is determined by the automatic or manual arrangement change, the contents of the delivery data table 230 and the delivery / object arrangement table 260 in FIGS. 3C and 3E are used using the new arrangement coordinates. Update.

  On the other hand, the object data, such as pipe data for water pipes, cannot be shifted like the symbol of the delivery data, so a process of highlighting is performed (step S22). Any method of highlighting is acceptable. For example, it is only necessary to change the brightness or the color so that it can be easily distinguished from a house, a road, or the like in the different area (which did not exist before the layer change). When the automatic placement function is not used, the delivery data symbol may be highlighted.

Finally, when the map information after the change by the above process is displayed and confirmed by the operator (step S23), this process ends.
FIG. 4 shows a display example related to the processing of FIG.

  FIG. 4 (a) shows a display example before changing the layer of an arbitrary map, and FIG. 4 (b) shows a symbol (icon etc.) linked to each delivery data on the map before the change. “Construction B”) and each object data (here, water pipe piping, valve plugs, etc.) are arranged and displayed.

  As a result of changing the layer related to the road from this state, it is assumed that one new road is added as shown in FIG. For this reason, as it is, the display part of the symbol “construction A” and the pipe of the water pipe overlaps with the display of the new road, which is difficult to understand. On the other hand, by shifting the symbol of “construction A” by the process of step S19 or performing the emphasis process of step S22, an appropriate display is performed as shown in FIG. However, in this example, since it overlaps the display of the original building this time, it may be better to manually move in step S21. In addition, although it may be difficult to understand in FIG. 4D, the object data (water pipe piping) is displayed in some form so that the water pipe piping and the newly added road can be distinguished. Is highlighted.
