Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that POI icons on a map become congested. <P>SOLUTION: A project information storage processing section 16 stores the project information of new delivery data in a POI information storage DB 32. A POI icon processing section 12 creates a POI icon corresponding to the project information. However, when different project information whose location information and procedure classification is the same as the new project information already exists, the new project information is also made to correspond to the POI icon corresponding to this different project information. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a POI icon display method.

  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. For example, there are systems that display various POI (Point of Interest) icons on a map and display information associated with the POI icons in advance when an arbitrary POI icon is designated by a user or the like.

  For example, in the CALS / EC (Continuous Acquisition and Life-cycle Support / Electronic Commerce) field, drawings, survey reports, photographs, etc. designed by civil engineering companies that were previously exchanged with paper are digitized. By doing so, paper-less and utilization of electronic data are promoted. Along with this, there is a need for a system to store and manage huge amounts of delivery data such as drawings and reports delivered from civil engineering-related companies to local governments and companies via electronic media or online. A map search system that links delivery data with delivery data has been proposed. In this map search system, a POI icon corresponding to each delivery data is displayed superimposed on a map, and when an arbitrary user designates an arbitrary POI icon, information regarding delivery data corresponding to this POI icon is displayed. As a result, it is possible to provide a system that is easy for the user to visually understand and use. Moreover, each data can be managed centrally on a map. The display position of each POI icon on the map is a position related to the delivery data associated with the POI icon. For example, a building (such as a building, a bridge, or a road) on which investigation, design, construction, or the like has been performed. The position of the object.

  CALS / EC is related to a standard for digitizing documents (delivery data) submitted to ministries and agencies such as the Ministry of Land, Infrastructure, Transport and Tourism. Support tools for digitizing delivery data in accordance with this standard are available. Already exists.

Regarding the system using the GIS, for example, in the car navigation field, icons indicating various facilities, stores, and the like are displayed on a map.
In the information management system (map search system) using the GIS as described above, the number of icons increases as the number of data items to be managed increases. When the display density of icons on the map increases, there are cases where icons overlap each other, which makes it difficult to understand and makes it difficult to operate even when specifying a desired icon. Particularly in the CALS / EC field, for example, for large buildings (buildings, etc.), it is common for multiple construction companies / investigation companies / design companies to be involved in surveys, design, construction, etc. over multiple years. Yes, since delivery data is submitted for each, a large number of icons are conventionally displayed densely at the location where the building is located on the map.

  For such a problem, for example, the technique of Patent Document 1 has been proposed. In the invention of Patent Document 1, for example, as shown in FIG. 1, it is disclosed to list and select all icons and road information that fall within a cursor of a predetermined size. The number does not decrease. Further, as shown in FIG. 2, Patent Document 1 proposes that when a plurality of icons are entered in the cursor, only one icon is left and the rest are erased to lower the icon display density. However, the display density is lowered only in the range in the cursor, and the user needs to operate the cursor one by one. In the first place, with this method of erasing icons, it becomes impossible to see information on the erased icons.

Further, Patent Document 2 discloses a group icon that associates a plurality of data with one icon as shown in FIG. Further, it is disclosed that data is visualized as a three-dimensional object, and further, for example, as shown in FIG.
JP 2002-98544 A JP-A-8-63324

  As described above, in the invention of Patent Document 1, even if the display density of the icons is reduced, only a limited range is temporarily performed, and further user operation is required. Furthermore, since the icon is deleted, there is a possibility that necessary data cannot be referred to. Further, as described above, in the method shown in FIG. 1 of Patent Document 1, the number of icons displayed is not reduced, so that it is difficult to see when the icons are densely packed. In particular, in the above CALS / EC map search system, a large number of icons may be displayed for one large building, and when a large number of icons are displayed in a wide range, It may happen that not all icons fall within the range. For this reason, it is inconvenient when it is desired to know all the delivery data related to the one large building. On the other hand, when the range of the cursor is widened, there is a possibility that icons related to other structures may be included this time, which is inconvenient when it is desired to know information about a specific building.

  On the other hand, it is conceivable to use the idea of the group icon described in Patent Document 2. That is, it is conceivable to associate a plurality of data (however, data of the same type) with one icon (hereinafter also referred to as “integration of icons” or “integrated icons”). However, it is necessary for humans to create such icons manually, and when the number of data is large, the amount of work becomes enormous. Also, when data is added later, the same work is required, and the work load increases.

  In addition, when the icons are integrated, even if only one icon is displayed, only one delivery data may be associated, or many data may be associated. There will be cases. In particular, in the map search system according to the CALS / EC field, the number of POI icons at the position of each building suggests the construction scale of the building or the like. Conventionally, the construction scale and the like can be estimated from the number of displayed POI icons, but cannot be estimated once the icons are integrated. Since it is related to the convenience of the user in the CALS / EC field that the construction scale of each place can be grasped at a glance on the displayed map, the construction scale of each place even if icon integration is performed. It is desirable to be able to grasp at a glance. In this regard, in Patent Document 2, the amount of file data is shown in the form of a three-dimensional object (for example, the shape of a building). However, if the amount of data is large, a large amount of space is taken up. Problems similar to crowding arise. In addition, the display process of such a three-dimensional object is complicated.

Furthermore, in the map search system according to the CALS / EC field, it is desired to be able to control whether each delivery data can be displayed for each user.
In particular, in large-scale construction, etc., investigation, design, construction, etc. are conducted over multiple years, so there may be multiple delivery data with the same project name (for example, the project name is ○ ○ There are cases where there are two delivery data for the construction embankment work, one for 2002 and one for 2003.

  The problem of the present invention is that, in particular, in a map search system related to the CALS / EC field, icons can be automatically integrated, or if the displayed map is viewed at a glance, the construction scale of each place can be grasped. Alternatively, a map search system that can display only the cases that can be browsed according to the authority of each user, displays a list of cases for each year, and improves the convenience of the user by any one or more of these, and its program Etc. is to provide.

  The map search system of the present invention stores map information storage means for storing map information, POI icon information storage means for storing the display position of each POI icon on the map, and each item data relating to each delivery data. Compare the location information and type included in each item data with the location information and type of each other item data, and all the item data with the same location information and type are the same. Each POI icon is arranged at a predetermined position on the map using the POI icon integration means associated with the POI icon and the information stored in the map information storage means and the POI icon information storage means in response to an arbitrary browsing request. When a map search screen is displayed and an arbitrary POI icon is specified, one or a plurality of item data associated with the POI icon is specified. Configured to have a display control means for performing shown.

  The map search system mainly relates to the CALS / EC field, and associates delivery data (such as case data) created and delivered in accordance with some delivery guidelines with a POI icon. However, a plurality of item data having the same position and type may be associated with one POI icon by the POI icon integration means. For example, in the case of project data related to construction of buildings such as buildings and bridges, the position means the location of the building, and the type means various operations related to construction such as survey, design, construction, etc. . In this example, there are various types of POI icons for each type of business, and according to the POI icon integration means, all the case data of the same business related to an arbitrary building are associated with one POI icon. .

  In this way, POI icons are automatically integrated without human work, and in the past, even in situations where many POI icons are concentrated at the position of one building, According to the present invention, the number of POI icons is reduced, and the convenience of the user is improved without taking the trouble of an administrator or the like.

  In the map search system, for example, each item data includes an authority to view the item data, and each user further includes user information storage means for registering the user authority of the user, and the display The control means compares the user authority of the user who made the browsing request with the browsing authority of each item data, and displays only the item data that the user is permitted to view at the time of the display. May be.

In this way, whether or not each delivery data can be displayed can be controlled for each user. In particular, since only the item data that can be browsed is presented from the beginning, no extra work is required.
In addition, for example, each POI icon further includes a number calculation processing means for calculating the number of item data associated with the POI icon, and the display control means You may make it display the said number of the said POI icons in the vicinity of the display position of a POI icon.

  When the above integration is performed, it becomes difficult to estimate the construction scale of the building from the degree of congestion of the POI icons. However, by displaying the number of item data associated with each POI icon, such a problem can be solved. Can be resolved.

  Further, for example, each item data includes year data of the item data, and the display control means classifies item data associated with the designated POI icon according to the year based on the year data. The list may be displayed.

  The list display displays, for example, item names of item data. After that, if you specify any project name, the details of that project data will be displayed. Here, in particular, in the case of a building having a large construction scale, work is often performed over a plurality of years, and delivery data may be delivered every year for the same project. The case names of such case data may be the same and cannot be distinguished. However, if the case names are classified and displayed for each year, they can be distinguished.

  According to the map search system of the present invention, the program thereof, and the like, a display method is provided that improves the convenience when the user browses each item information, particularly in the map search system according to the CALS / EC field. That is, for example, icons can be automatically integrated, and even if there is a lot of project information related to the same location (building etc.) on the map, the icons are dense and difficult to see, It is not difficult to designate an arbitrary icon, and it is not necessary for humans to work one by one for icon integration. This improves the convenience for the user and greatly reduces the work load on the administrator or the like. Or, for example, if the displayed map is viewed at a glance, the construction scale of each place can be grasped. Alternatively, for example, only cases that can be browsed according to the authority of each user can be displayed as a list and can be selected, and a useless effort of specifying and rejecting cases that cannot be browsed can be saved. Further, for example, a list of cases is displayed for each year so that each case data of work over a plurality of years can be distinguished.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a configuration diagram of the map search system of the present embodiment.
The illustrated map search system 1 is a map search system according to the CALS / EC field described above. Therefore, the information handled by the system 1 is information regarding electronic data (delivery data) created and delivered in accordance with the electronic delivery guidelines designated by each ministry and local government such as the Ministry of Land, Infrastructure, Transport and Tourism.

The illustrated map search system 1 (server) is connected to a network (not shown), and can exchange data with an arbitrary user terminal 2 (client).
The illustrated map search system 1 is roughly composed of a processing unit 10 and a storage unit 30. The processing unit 10 is realized by a CPU and a predetermined application program. The storage unit 30 stores various data necessary for executing various processes by the processing unit 10 in, for example, a hard disk. The map search system 1 can be realized by a general-purpose personal computer or the like.

  The processing unit 10 includes various processing units such as an authentication processing unit 11, a POI icon processing unit 12, a map data display processing unit 13, a case information list display processing unit 14, a case information detail display processing unit 15, and a case information storage processing unit 16. Have The POI icon processing unit 12 includes a display icon setting processing unit 21, an authority processing unit 22, a number calculation processing unit 23, a map data conversion processing unit 24, a display authority adding processing unit 25, and the like. As described above, the processing of these various processing units (in other words, the processing of the flowcharts shown in FIGS. 2A and 2B and FIGS. 6A and 6B) is previously stored in, for example, the storage unit 30 or the like. This is realized by the CPU reading and executing the stored application program.

The storage unit 30 includes a system data storage DB (database) 31, a POI information storage DB (database) 32, and a map data storage DB (database) 33.
The system data storage DB 31 stores information about the user who uses the system 1 (its authority, etc.). For example, the user data table 40 and the authority information table 50 shown in FIGS. Storing.

  The POI information storage DB 32 stores, for example, a delivery data table 60 shown in FIG. 3C described later, a POI table 80 shown in FIGS. 4A and 4B, a delivery item type definition table 90, and delivery data. Here, a part of the delivery data (management file information = project information) is stored. As an example, FIG. 5 (a) and FIG. 5 (b) show the civil engineering design work data table 110, construction completed book data. A table 130 is shown.

  The map data storage DB 33 stores, for example, a map data file table 100 and actual map image information shown in FIG. Furthermore, in this example, when there is a request from any user terminal 2, the information created by the POI icon processing unit 21 and various information read from the POI information storage DB 32 are displayed by the map data conversion processing unit 24. For example, information (POI map data described later) converted into a format that can be displayed by the browser of the user terminal 2 is stored. Note that the present invention is not limited to this example, and the conversion process may not be performed as will be described later.

  For example, when accessed from any user terminal 2, the authentication processing unit 11 causes the user to input an ID, a password, etc., refers to the system data storage DB 31, performs user authentication, and if authentication is OK. Then, the POI icon processing unit 12 is called.

  The POI icon processing unit 12 called by the authentication processing unit 11 first extracts, as the display target, only the item information for which the user has the viewing authority by the authority processing unit 22, and then the number calculation processing unit 23 extracts each POI. The number of item information associated with the POI icon is calculated for each icon, and finally, the map data conversion processing unit 24 converts the number of items, item information, icons, map information, etc. into a format that can be displayed by a browser, for example. This is converted and stored in the map data storage DB 33. Various information stored in the map data storage DB 33 in this way for displaying on the user terminal 2 the information search / display screen on the map as shown in FIGS. Hereinafter, it will be collectively referred to as POI map data.

  In some cases, the display icon setting processing unit 21 associates a plurality of pieces of item information with one POI icon. In addition, the browsing authority is set in advance for each item information by the administrator of the system 1 through the display authority addition processing unit 25 in advance.

  In this example, a part of the delivery data (management file information to be described later = information shown in FIGS. 5A and 5B, for example) is displayed, and this is referred to as the case information. However, the present invention is not limited to this example, and all of the delivery data may be displayed. In this case, the item information means delivery data.

  The map data display processing unit 13 transmits the POI map data stored in the map data storage DB 33 to the user terminal 2 (client side) that is the access source. The user terminal 2 includes a Web browser, and based on the POI map data, first, for example, a POI map data display screen 150 as shown in FIG. At that time, as shown in FIG. 7A, the number of cases calculated by the number-of-cases calculation processing unit 23 is displayed near the display position of each POI icon. In this state, when the user of the user terminal 2 designates an arbitrary POI icon, the case information list display processing unit 14 displays, for example, the case information list screen 160 shown in FIG. 7B based on the POI map data. And displayed on the display of the user terminal 2. Further, when the user selects an arbitrary case on the screen 160, the case information detail display processing unit 15 displays a case information detail screen 170 shown in FIG. 7C on the display of the user terminal 2, for example.

  Here, the map data display processing unit 13, the case information list display processing unit 14, and the case information detail display processing unit 15 are shown separately, but these are regarded as one processing function (display control function). May be.

  When the newly received delivery data is sent from, for example, an electronic delivery system 182 shown in FIG. 8 to be described later, the case information storage processing unit 16 transfers a part or all of this delivery data to the POI information storage DB 32. Process to store in. An example of the delivery data is shown in FIG. 9, and each data in the management file included in the delivery data is stored in the tables 110 and 130 shown in FIGS. 5 (a) and 5 (b). .

Hereinafter, the map search system 1 having the above configuration will be described in more detail with reference to FIG.
FIG. 2A is a process flowchart of the POI icon processing unit 12 when there is a browsing request from the arbitrary user terminal 2 described above. FIG. 2B is a flowchart of the registration process related to the new delivery data described above.

Here, the process of FIG. 2B will be described first.
The process of FIG. 2B is executed periodically, for example, and the POI icon processing unit 12 first determines whether there is new case information (step S31). As described above, when there is new delivery data, since the data (case information) of the management file is stored in the tables 110, 130, etc. by the case information storage processing unit 16, the new information is stored in the tables 110, 130. The determination in step S31 is made based on whether or not a record has been added. If there is no new item information (step S31, NO), this process ends.

If there is new item information, the process proceeds to step S32 and subsequent steps, and new records are created and added to the delivery data table 60 and the POI table 80 with respect to the new item information.
Here, as a specific example, it is assumed that the record with Nouhin_ID 111 of “3” shown in FIG. 5A is the item information of the new delivery data, and FIGS. 3C and 4A show this processing. It is assumed that the later state is shown. Therefore, at the present stage, it is assumed that the last record shown in FIG. 3C (Nouhin_ID 61 is “3”) has not yet been created.

  First, the authority to refer to the new item information is set by the display authority addition processing unit 25. For example, an authority setting screen (not shown) is displayed on the display of the map search system 1 (server), for example, and a system administrator or the like sets desired one or more authority IDs (step S32).

  When the setting is completed, the display icon setting processing unit 21 executes the processes of steps S33 to S39. First, a new record is created and added to the delivery data table 60 based on the set authority ID and the new item information record stored in the table 110 or 130 (step S33).

  That is, a new record is added to the delivery data table 60, the authority ID set above is stored in the authority ID 70 of this record, and the table of Nouhin_ID 61, case name 63, year 64, and item type ID 68 is stored in each field. Data of 110 Nouhin_ID 111, case name 112, year 113, and procedure type ID 143 is stored. Further, based on West_Pos 119 to south_pos 122 of the table 110, the location (latitude, longitude) of the building or the like related to the delivery data is calculated (position coordinates such as the center of the area occupied by the building), and the X_keido 66 of the table 60 , Y_ido67. Note that Nouhin_ID 111 is a unique identification number arbitrarily assigned to each received delivery data.

  Then, the newly added record is compared with other existing records to determine whether or not a record having the same position (X_keido 66, Y_ido 67) and procedure type ID 68 as the newly added record already exists (step) S34). If a record having the same position and type as the newly added record already exists, the POI icon associated with the new matter information is the POI icon already created in association with the existing matter information. It is determined that the POI icon is to be integrated (step S35, YES), and POI icon integration processing is performed (step S36). Note that even in the integration process, the value of the POI_ID 62 of the records having the same position and the same kind of procedure may be simply stored in the POI_ID 62 of the newly added record. In the above example, the newly added Nouhin_ID 61 = '3' record position and procedure type are the same as the Nouhin_ID 61 = '1' record location and procedure type, so the Nouhin_ID 61 = '3' record POI_ID 62 In this case, “1” is stored.

The procedure type is determined by the corresponding delivery procedure 92 and the business type 93 as shown in FIG.
Finally, a registration state addition process is performed (step S39). In this case, data indicating registration completion (here, “1”) is stored in the Nouhin_Status 65 of the newly added record.

  On the other hand, if there is no other record having the same position and type as the newly added record (NO in step S35), it is necessary to create a new POI icon corresponding to the new case information, so step S37. , S38 is executed. That is, first, a new POI_ID is arbitrarily assigned and stored in the POI_ID 81 of the new record added to the POI table 80. Further, the procedure type ID 123 of the new case information is stored in the procedure type ID 89. Further, the above X_keido 66 and Y_ido 67 are converted into the coordinates of a plane rectangular coordinate system (19 coordinate system) and stored in X87 and Y88. Further, such coordinates are converted into display position coordinates on the display and stored in X_Pos84 and Y_Pos85 (step S37). Further, the corresponding map information is obtained from the coordinates of the latitude and longitude, the Area_ID 101 corresponding to the obtained map information is obtained by referring to the map data file table 100 shown in FIG. (Step S38). X87 and Y88 are for storing the original position information in consideration of the user moving the icon.

  Finally, a registration state addition process is performed (step S39). In this case, data indicating registration completion (here, “1”) is stored in the Nouhin_Status 65 of the delivery data table 60, and data indicating registration completion (here, “1”) is also stored in the Poi_Status 82 of the POI table 80. ).

  As described above, if there is new matter information, registration related to the new matter information is performed in the delivery data table 60 and the POI table 80 as necessary, and each time there is a request from an arbitrary user, Using the tables 60 and 80, the POI map data is created and displayed by the process of FIG.

  In FIG. 2A, first, user authentication processing is performed by the authentication processing unit 11 (step S11), and if it is authentication NG (step S12, NO), login to the user terminal 2 that is the access source is prohibited. It is displayed (step S13). On the other hand, if the authentication is OK (step S12, YES), the process proceeds to step S14 and subsequent steps.

  First, the authority processing unit 22 recognizes the authority of the accessing user and extracts all item information permitted to be browsed according to this authority (step S14). In this process, as a specific example, first, the authority ID of this user is acquired with reference to the user information table 40 shown in FIG. The user information table 40 includes data items of a user ID 41, a user name 42, affiliation names 43 and 44, and an authority ID 45. During the authentication process, the user inputs his / her user ID (employee number, etc.), name, etc., and the authority processing unit 22 obtains a record corresponding to this user in the table 40, and the authority of this record Get all ID45. The authority ID 45 is determined and set in advance based on, for example, the authority information table 50 shown in FIG. The authority information table 50 gives each authority ID for each department. That is, a department name (affiliated department 52, 53, etc.) to which the authority ID 51 is given is stored in association with each authority ID 51. Therefore, in this example, each user is given the authority given to the department to which the user belongs. Of course, the present invention is not limited to this example, and authority may be given to each user individually.

  Next, using the acquired authority ID 45, the delivery data table 60 shown in FIG. 3C is searched to extract all corresponding records. That is, all records in which one of the one or more authority IDs stored in the authority ID 70 in the table 60 is the same as one of the one or more authority IDs of the user are extracted. Set as conversion target (that is, display target data). Then, using the extracted records, the number of records associated with each POI_ID is calculated (step S15). If all the records shown in FIG. 3C are to be displayed, there are two records associated with the POI icon with POI_ID = “1”.

  In order to accurately grasp the construction scale, the processing in step S15 may calculate the number of all pieces of case information associated with each POI icon regardless of authority. Good (because in the above processing, the number of cases smaller than the actual construction scale is displayed for a low-privileged user). Alternatively, it is possible to display all item information without performing processing for extracting item information that can be displayed by the authority.

  After step S16, basically, the process of creating the POI map data is performed as usual, but the point different from the conventional one is that a plurality of item information may be associated with one POI icon, As shown in FIG. 7 (b), data for classifying and displaying a list of item names of a plurality of item information by year is created in step S17, and the calculated number is displayed in the vicinity of the POI icon. The data to be displayed is created. Except for these points, conventional POI map data creation processing is performed.

  The POI map data creation processing is to convert the data of various tables stored in the POI information storage DB 32 into a format that can be displayed by, for example, the browser of the user terminal 2, and an XML-related format such as SVG, for example. Since this conversion process itself is a conventional technique, it will not be described in particular. SVG (Scalable Vector Graphics) is an XML-based 2D vector image description language, and is a standard for describing two-dimensional graphics in XML format. In the XML-related format, various data stored in the POI information storage DB 32 can be described by a tag or attribute, for example, in a format for displaying the screen shown in FIGS.

  Note that the above conversion process is not always necessary (of course, it is necessary when a browser is used). The background map may be obtained simply by acquiring a map image file from the table 100 and displayed, and the image of each icon, the corresponding background map, and the display position on the map can be understood by referring to the tables 80 and 90. Therefore, the display of FIG. 7A may be performed using these. Similarly, the data necessary for the display in FIGS. 7B and 7C can also be obtained by referring to the tables 60, 80, 110, 130, etc., so that these data can be displayed in any existing format. Good.

  If the process after step S16 is demonstrated easily, first, the data acquisition for displaying each POI icon on a map will be performed (step S16). That is, the background map for displaying each POI icon, information on the display position, and icon image data are acquired. With respect to the icon image data, the delivery file type definition table 90 in FIG. 4B is referred to by the program type ID 89 in the POI table 80, and the icon file 94 of the corresponding record is acquired. The background map and the display position information are used to acquire data of Area_ID 83, X_Pos84, and Y_Pos85.

  Thereafter, the following steps S17 to S19 are executed for each POI icon. That is, each POI icon is sequentially processed, and information associated with the POI icon is converted into an XML-related format.

  First, with reference to the delivery data table 60, the Nouhin_ID 61, the case name 63, and the year 64 of all the records corresponding to the POI_ID to be processed (but limited to those to be converted) are acquired, and the case names are classified by year. Are converted into an XML-related format (step S17). That is, data for displaying the list screen 160 shown in FIG. 7B on the browser side is generated. Further, display target data items set in advance are extracted from the case information stored in the tables 110 and 130, and are converted into an XML-related format (step S18). That is, data for displaying the detailed screen 170 shown in FIG. 7C on the browser side is generated.

  Finally, a description for displaying the number of cases calculated in step S15 in the vicinity of the POI icon is given (step S19). For example, by adding a predetermined amount to the display position coordinates (X_Pos84, Y_Pos85) of the POI icon (in the example shown in FIG. 7A, only the Y coordinate is added), the display position coordinates of the number of cases are determined. .

  By creating POI map data in a format that can be displayed by the browser by the above-described processing, as shown above, the map data display processing unit 13 causes the browser on the user terminal 2 side to display, for example, as shown in FIG. The map data display screen 150 is displayed.

  As shown in FIG. 7A, the number of cases calculated by the number calculation processing unit 23 is displayed near the display position of each POI icon. As a result, the number of projects (construction scale) such as a building at the position where each POI icon is displayed can be grasped at a glance. In addition, in the example shown in FIG. 7A, three POI icons are displayed. However, the number of cases associated with each POI icon is 21 in the example shown, that is, 5 cases, 4 cases, and 12 cases. Conventionally, 21 POI icons are displayed and it is very difficult to see and operate, but in this example, such a problem can be solved.

  When the user clicks a desired POI icon on this screen 150, the case information list display processing unit 14 executes the process shown in FIG. 6A, and the case information list screen 160 shown in FIG. 7B. Is displayed. In the process of FIG. 6A, when the user clicks a desired POI icon (step S41), the data created in step S17 regarding the POI icon is acquired (step S42), and FIG. Is displayed on the display of the user terminal 2 (step S43). As illustrated, the case names of the case information associated with the designated POI icon are displayed in a form classified by year. As shown in the figure, even if multiple project information with the same project name exists, they can be distinguished by year, and work such as survey, design, construction, etc. over the years related to the building etc. at the position indicated by the POI icon The history becomes easy to grasp and the convenience for the user is improved.

  Furthermore, according to the authority each user has, only the item information for which the user has browsing authority is displayed in a list. In this case, if you click the “Details” button for any case, you can always refer to the detailed information for that case (it will not be refused to view at this stage), so the user may perform extra operations. Disappear.

  Further, when the user clicks the “detail” button corresponding to the desired case name on the list screen 160 (step S51), the case information detail display processing unit 15 describes the contents described in step S18 regarding the POI icon. By acquiring the description data of the designated case (step S52), a case information detail screen 170 as shown in FIG. 7C, for example, is displayed (step S53). Of course, as already described, data such as reports, CAD drawings and photographs in the delivery data may also be displayed.

Finally, a system that the system 1 cooperates will be described.
As shown in FIG. 8, the map search system (GIS) 1 of this example is connected to an electronic delivery system 182 via a local network (such as a LAN 183). The electronic delivery system 182 is connected to the orderer authentication system 181 via the LAN 183. The orderer authentication system 181 checks whether or not the delivery source is an authorized orderer when the delivery data is sent from an external orderer via the Internet (not shown). Process). The electronic delivery system 182 accepts delivery data and stores it if the check by the orderer authentication system 181 is OK. For example, as shown in FIG. 9, the delivery data is composed of text-format document data, CAD drawing data, photo data, and the like, and further has a management file for these various data. In the above description, the electronic delivery system 182 passes the received delivery data to the system 1, but only the management file may be passed to the map search system 1.

  The display of the map search screen is not limited to the client, but may be displayed on the screen of the map search system 1 (server). In addition, the process of FIG. 2B is not limited to when new item information is added, for example, all items that have already been delivered in a state where one item information is not yet registered in the table 60 or the like. You may make it perform sequentially about matter information. In addition, with respect to the user authentication, registration and login can be performed in cooperation with an authentication system or the like that stores assigned business information, user information, and construction information in other systems. Further, the tables 110 and 130 shown in FIG. 5 are examples in which a table is prepared for each business type, and each item information is stored in the corresponding table according to the business type. Absent.

It is a block diagram of the map search system of this embodiment. (A) is a POI map display process at the time of user use, (b) is a flowchart showing a new delivery data registration process.
