[0004] [Patent Document 1] JP 2020-123332 A Summary of the Invention [Problem to be solved by the invention]

[0005] Even if the land is registered, the Article 14 map or other drawings showing the current location (hereinafter referred to as the site) and shape of the land are closed, and even if you search the G Spatial Information Center by the land name and land number of the land, there are no hits, and it is sometimes impossible to obtain electronic data that can identify the location and shape of the land. This often occurs in cases where the land is currently the site of a long and narrow object such as a road or waterway.

[0006] The present invention has been made in consideration of the above-mentioned situation, and one of its objectives is to provide an on-site confirmation system, an on-site confirmation method, and a program that can confirm the location and shape of registered land even if the drawings showing the location and shape of the land are closed. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0016] 1 is a diagram showing an example of the configuration of an on-site confirmation system 10 according to an embodiment of the present invention. The on-site confirmation system 10 is a computer system capable of confirming the location (site) and shape of a polygon on a map provided by a registry office, which is associated with land specified by a place name and a place number, for example.

[0017] As shown in FIG. 1, the on-site inspection system 10 includes a processor 10a, a storage unit 10b, a communication unit 10c, an output unit 10d, and an input unit 10e.

[0018] The processor 10a is a program-controlled device such as a CPU, and executes various information processes according to programs stored in the memory unit 10b. The memory unit 10b is, for example, a storage element such as a ROM or RAM, or a solid-state drive. The memory unit 10b stores programs executed by the processor 10a. The communication unit 10c is a communication interface for sending and receiving data. The output unit 10d is, for example, a display unit such as a display that displays and outputs information according to instructions input from the processor 10a. The input unit 10e is, for example, a mouse, a keyboard, or the like that outputs the contents of operations performed by the user to the processor 10a.

[0019] In this embodiment, for example, as shown in FIG. 2, when the search screen 20 is displayed on the output unit 10d, the user inputs a search criteria string such as "155, C town, B city, A prefecture" into the input form 22 arranged on the search screen 20 via the input unit 10e and clicks the search button 24 arranged on the search screen 20, and the map image 26a shown in FIG. 3 is displayed on the output unit 10d.

[0020] Furthermore, as shown in FIG. 4, when the search screen 20 is displayed on the output unit 10d, the user inputs a search criteria string such as "187, C town, B city, A prefecture" into the input form 22 arranged on the search screen 20 via the input unit 10e and clicks the search button 24, and the map image 26b shown in FIG. 5 is displayed on the output unit 10d.

[0021] For example, a polygon representing a piece of land with the place name and lot number "155, C-cho, B-city, A-prefecture" is shown in electronic data of a map provided by the G-spatial information center. In this case, as shown in Fig. 3, a map image 26a is displayed on the map provided by the registry office, in which the polygon P1 representing the piece of land is identified.

[0022] On the other hand, even though the land with the place name and land number "187, C-cho, B-city, A-prefecture" is registered, the polygon representing said land is not shown in the electronic data of the registry office map provided through the G Spatial Information Center. For example, when a cadastral survey is conducted, the previous Article 14 map or other drawing is closed and a new Article 14 map or other drawing is created, and the location and shape of the registered land are omitted from this new Article 14 map or other drawing, making it impossible to confirm. In such a situation, even if you search the G Spatial Information Center for the place name and land number "187, C-cho, B-city, A-prefecture", there will be no hits, and you will not be able to obtain electronic data that can identify the location and shape of the land.

[0023] However, in this embodiment, even in such a situation, as shown in Figure 5, a map image 26b is displayed in which a polygon P2 representing the land associated with the place-name and lot number "187, C-cho, B-city, A-prefecture" and a polygon P3 representing the site containing that land on the registry office map are identified.

[0024] In this way, according to this embodiment, even if the drawing showing the location and shape of the registered land is closed, it is possible to confirm the location and shape of the land.

[0025] The functions of the on-site inspection system 10 according to this embodiment and the processes performed by the on-site inspection system 10 will be further described below.

[0026] Fig. 6 is a functional block diagram showing an example of functions implemented in the on-site inspection system 10 according to this embodiment. Note that the on-site inspection system 10 according to this embodiment does not need to implement all of the functions shown in Fig. 6, and functions other than the functions shown in Fig. 6 may also be implemented.

[0027] As shown in FIG. 6, the on-site confirmation system 10 according to the present embodiment functionally includes, for example, a civil data storage unit 30, a land master data storage unit 32, an on-site unconfirmable area identification unit 34, a search target data storage unit 36, a search condition character string reception unit 38, a search unit 40, a determination unit 42, a map image generation unit 44, and a map image output unit 46. The civil data storage unit 30, the land master data storage unit 32, and the search target data storage unit 36 ​​are mainly implemented in the storage unit 10b. The on-site unconfirmable area identification unit 34, the search unit 40, the determination unit 42, and the map image generation unit 44 are mainly implemented in the processor 10a. The search condition character string reception unit 38 is mainly implemented in the processor 10a and the input unit 10e. The map image output unit 46 is mainly implemented in the processor 10a and the output unit 10d.

[0028] The above functions may be implemented by executing a program including instructions corresponding to the above functions, which is installed in the on-site inspection system 10, which is a computer, on the processor 10a. This program may be supplied to the on-site inspection system 10 via a computer-readable information storage medium, such as an optical disk, a magnetic disk, a magnetic tape, a magneto-optical disk, or a flash memory, or via the Internet, for example.

[0029] In this embodiment, the civil data storage unit 30 stores multiple pieces of civil data including, for example, civil polygon data indicating polygons on a map provided by the registry office (see Figure 7) and civil attribute data 50 indicating the attributes of the land represented by the polygon (see Figures 8 and 9).

[0030] For example, the on-site confirmation system 10 may obtain electronic data of a registry office-attached map (Article 14 map, etc.) held by the Legal Affairs Bureau by accessing the G-spatial information center via the communication unit 10c. Then, the civil data generated based on the electronic data may be stored in the civil data storage unit 30.

[0031] Fig. 7 is a diagram showing an example of a map image 26c on which polygons indicated by civil polygon data included in each of a plurality of civil data are drawn. The civil polygon data may include, for example, data indicating the latitude and longitude of the vertices of the polygons indicated by the civil polygon data. The polygons indicated by these civil polygon data include, for example, civil polygon data indicating polygon P1 indicated in the map image 26a shown in Fig. 3 and civil polygon data indicating polygon P3 indicated in the map image 26b shown in Fig. 5, as shown in Fig. 7.

[0032] 8 and 9 are diagrams showing an example of the civil attribute data 50. As shown in FIG. 8 and FIG. 9, the civil attribute data 50 includes a civil polygon ID and civil place name and land number data. The civil polygon ID included in the civil attribute data 50 is an identifier of the civil polygon data associated with the civil attribute data 50. The civil place name and land number data included in the civil attribute data 50 is data indicating the place name and land number of the land represented by the polygon identified by the civil polygon ID included in the civil attribute data 50. The civil place name and land number data includes, for example, prefecture name data, city, ward, town, village name data, oaza name and town name data, land name and chome data, and land number data indicating the name of the prefecture, city, ward, town, village name data, land name and chome data, respectively, to which the land belongs.

[0033] Fig. 8 is a diagram showing an example of civil attribute data 50a associated with the place name and parcel number "155, C-cho, B-city, A-prefecture". Fig. 9 is a diagram showing an example of civil attribute data 50b associated with the place name and parcel number "Road-1, C-cho, B-city, A-prefecture". Note that "Road-1" is not a parcel number, but for convenience, it is treated as a parcel number here.

[0034] Hereinafter, the value of civil place name and address data refers to a character string that is a combination of a character string that is the value of prefecture name data included in the civil place name and address data, a character string that is the value of city / ward / town / village name data included in the civil place name and address data, a character string that is the value of oaza name / town name data included in the civil place name and address data, a character string that is the value of za name / chome data included in the civil place name and address data, and a character string that is the value of address data included in the civil place name and address data.

[0035] In this embodiment, a polygon on the registry office map shown in Fig. 7 is associated with the place name and lot number of the land represented by the polygon by a civil polygon ID. Here, the polygon identified by the civil polygon ID "000000312" included in the civil attribute data 50a shown in Fig. 8 is assumed to be polygon P1 shown in Fig. 7. This polygon P1 is identified and displayed in the map image 26a shown in Fig. 3. Moreover, the polygon identified by the civil polygon ID "000000812" included in the civil attribute data 50b shown in Fig. 9 is assumed to be polygon P3 shown in Fig. 7. This polygon P3 is identified and displayed in the map image 26b shown in Fig. 5.

[0036] In this embodiment, a unique civil polygon ID is assigned to each polygon included in the civil polygon data. Even in cases where the same land address data value is assigned to different polygons that are managed separately in multiple files, in this embodiment, different civil polygon IDs are set for these polygons.

[0037] In this embodiment, the land master data storage unit 32 stores multiple pieces of land master data including, for example, land master attribute data 52 (see Figures 11 and 12) indicating the attributes of the land registered in the registry, and land master polygon data indicating the polygon representing the land on a map (see Figure 10).

[0038] Fig. 10 is a diagram showing an example of a map image 26d in which polygons indicated by land master polygon data included in each of a plurality of land master data are drawn. The land master polygon data may include, for example, data indicating the latitude and longitude of vertices of the polygons indicated by the land master polygon data. The polygons indicated by these land master polygon data include, for example, land master polygon data indicating polygon P2 indicated in the map image 26b shown in Fig. 5, as shown in Fig. 10.

[0039] In this embodiment, for example, the name and address of all the registered land may be listed using a registration information service provided by the General Incorporated Foundation People's Law Association. The location and shape of the land corresponding to each listed name and address may be confirmed by using an aerial photograph, a general topographical map, a Article 14 map (including past ones), an administrative address map owned by the asset tax department of a local government, a map related to farmland (see Article 52-3, paragraph 2 of the Farmland Law), a map related to forest land (see Article 191-5, paragraph 2 of the Forest Law), a forest plan map, etc. Furthermore, for unregistered land (unregistered long and narrow properties, etc.), the location and shape of the land may be confirmed by using a national property specific drawing (attached drawing to the application for non-statutory public property transfer). Then, land master polygon data may be generated based on the location and shape of the land confirmed in this way. Furthermore, the accuracy of the polygon indicated by the land master polygon data may be verified using a tax ledger, a farmland ledger, a forest land ledger, etc.

[0040] 11 and 12 are diagrams showing an example of the land master attribute data 52. As shown in FIG. 11 and FIG. 12, the land master attribute data 52 includes a land master polygon ID and land master place name and land number data. The land master polygon ID included in the land master attribute data 52 is an identifier of the land master polygon data associated with the land master attribute data 52. The land master place name and land number data included in the land master attribute data 52 is data indicating the place name and land number of the land represented by the polygon identified by the land master polygon ID included in the land master attribute data 52. The land master place name and land number data includes, for example, prefecture name data, city ward town village name data, oaza name town name data, oaza name chome data, and land number data indicating the name of the prefecture, city ward town village name data, oaza name town name chome data, and land number data, respectively, of the prefecture, city ward town village name data, oaza name town name chome data, and land number data to which the land belongs.

[0041] Fig. 11 is a diagram showing an example of the civil attribute data 50a associated with the place name and land number "155, C town, B city, A prefecture". Fig. 9 is a diagram showing an example of the civil attribute data 50b associated with the place name and land number "187, C town, B city, A prefecture".

[0042] Hereinafter, the value of the land master place name and address data refers to a string that is a combination of a character string that is the value of the prefecture name data contained in the land master place name and address data, a character string that is the value of the city / ward / town / village name data contained in the land master place name and address data, a character string that is the value of the oaza name / town name data contained in the land master place name and address data, a character string that is the value of the za name / chome data contained in the land master place name and address data, and a character string that is the value of the address data contained in the land master place name and address data.

[0043] In this embodiment, a polygon on a map is associated with the place name and place number of the land represented by the polygon by a land master polygon ID. Here, the polygon identified by the land master polygon ID "1610102310000185" included in the land master attribute data 52a shown in Fig. 11 is assumed to be polygon P4 shown in Fig. 10. Also, the polygon identified by the land master polygon ID "1610102310000167" included in the land master attribute data 52b shown in Fig. 12 is assumed to be polygon P2 shown in Fig. 10. This polygon P2 is displayed in an identifiable manner in the map image 26b shown in Fig. 5.

[0044] In this embodiment, a unique land master polygon ID is assigned to each polygon included in the land master polygon data.

[0045] In this embodiment, the unconfirmable land identification unit 34, for example, identifies land master data of unconfirmable land from among the multiple land master data based on the civil land name and land number data included in each of the multiple civil data and the land master land name and land number data included in each of the multiple land master data. Here, the unconfirmable land refers to land that is registered but is not found when a search is performed by the G-spatial information center based on the land name and land number of the land.

[0046] Here, the unconfirmable land identification unit 34 may, for example, identify the value of the land master name and address data included in each of the multiple land master data.The unconfirmable land identification unit 34 may then determine whether or not there is civil data including the civil name and address data in which the identified value is set.The unconfirmable land identification unit 34 may then identify the land master data in which such civil data does not exist as land master data of an unconfirmable land.

[0047] In addition, the unconfirmable area specifying unit 34 may generate search target data 54 exemplified in Fig. 13 and Fig. 14. Here, for example, the unconfirmable area specifying unit 34 may generate search target data 54 associated with each of a plurality of land master data.

[0048] As shown in FIG. 13 and FIG. 14, the search target data 54 includes a land master polygon ID, a civil polygon ID, place name and lot number data, and an unconfirmable land flag.

[0049] For example, the value of the land master polygon ID included in the search target data 54 associated with land master data is set to the land master polygon ID included in the land master data.

[0050] Then, for example, the civil polygon ID of a polygon indicated by the civil polygon data, which is a polygon that includes the land represented by the polygon indicated by the land master polygon data identified by the land master polygon ID included in the land master data, is set as the civil polygon ID included in the search target data 54 associated with the land master data. For example, a polygon indicated by the civil polygon data, which is a polygon that includes the land represented by the polygon indicated by the land master polygon data, may be specified by executing a spatial calculation. Then, the civil polygon ID of the specified polygon may be set as the civil polygon ID included in the search target data 54.

[0051] The value of the prefecture name data, the value of the city / ward / town / village name data, the value of the oaza name / town name data, the value of the block / chome data, and the value of the land number data contained in the search target data 54 associated with the land master data are set to the value of the prefecture name data, the value of the city / ward / town / village name data, the value of the oaza name / town name data, the value of the block / chome data, and the value of the land number data in the block / chome data contained in the land master data, respectively.

[0052] Hereinafter, the value of the place name and address data contained in the search target data 54 refers to a character string which is the value of the prefecture name data contained in the place name and address data, a character string which is the value of the city, ward, town, or village name data contained in the place name and address data, a character string which is the value of the oaza name and town name data contained in the place name and address data, a character string which is the value of the za name and chome data contained in the place name and address data, and a character string which is the value of the address data contained in the place name and address data.

[0053] The value of the land that cannot be confirmed on site flag included in the search target data 54 associated with the land master data is set to 1 if the land master data is land master data for a land that cannot be confirmed on site, and set to 0 if not.

[0054] FIG. 13 is a diagram showing an example of search target data 54a associated with the place name and land number "A prefecture, B city, C town 155". The search target data 54a shown in FIG. 13 is generated based on the civil attribute data 50a shown in FIG. 8 and the land master attribute data 52a shown in FIG. 11. Here, assume that civil data including civil place name and land number data whose value is "A prefecture, B city, C town 155" exists as shown in FIG. 8. In this case, as shown in FIG. 13, the value of the on-site unconfirmable land flag of the search target data 54a is set to 0. In addition, the value of the civil polygon ID included in the civil attribute data 50a shown in FIG. 8 is set to the value of the civil polygon ID included in the search target data 54a shown in FIG. 13. In addition, the value of the land master polygon ID included in the land master attribute data 52a shown in FIG. 11 is set to the value of the land master polygon ID included in the search target data 54a shown in FIG. 13. In this manner, the polygon P1 shown in FIG. 7 and the polygon P4 shown in FIG. 10 are associated with each other by the search target data 54a shown in FIG.

[0055] FIG. 14 is a diagram showing an example of search target data 54b associated with the place name and land number "A prefecture, B city, C town 187". The search target data 54b shown in FIG. 14 is generated based on the civil attribute data 50b shown in FIG. 9 and the land master attribute data 52b shown in FIG. 12. Here, assume that there is no civil data including the civil place name and land number data whose value is "A prefecture, B city, C town 187". In this case, as shown in FIG. 14, the value of the on-site confirmation impossible land flag of the search target data 54b is set to 1. In addition, the value of the land master polygon ID included in the land master attribute data 52b shown in FIG. 12 is set to the value of the land master polygon ID included in the search target data 54b shown in FIG. 14. As described above, the polygon identified by the land master polygon ID is polygon P2 shown in FIG. 10.

[0056] Then, by executing a spatial operation, polygon P3 shown in Figure 7 is identified, which is a polygon indicated by the civil polygon data and is a polygon that encompasses the land indicated by polygon P2 shown in Figure 10. Then, the value "000000812" of the civil polygon ID (see Figure 9) corresponding to polygon P3 is set as the value of the civil polygon ID included in the search target data 54b shown in Figure 14.

[0057] In this manner, the polygon P3 shown in FIG. 7 and the polygon P2 shown in FIG. 10 are associated with each other by the search target data 54b shown in FIG.

[0058] In this way, the on-site verification impossible area identification unit 34 generates search target data 54 that corresponds to the land master data for all land master data, and stores the generated search target data 54 in the search target data memory unit 36.

[0059] In this embodiment, the search target data storage unit 36 ​​stores, for example, the search target data 54 generated by the unconfirmable location specifying unit 34 .

[0060] In this embodiment, the search condition character string receiving unit 38 receives, for example, a search condition character string indicating a place name and a place number. The search condition character string receiving unit 38 may receive a search condition character string input by a user of the site inspection system 10 as described above.

[0061] In this embodiment, the search unit 40 identifies the search target data 54 that satisfies the search conditions determined based on the search condition string received by the search condition string receiving unit 38. Here, for example, the search unit 40 may determine, as the search condition, that "the value of the included place name and land number data completely matches the search condition string." Then, the search target data 54 that satisfies the search condition determined in this manner may be identified.

[0062] For example, when the search condition character string is "A prefecture, B city, C town 155" as shown in Fig. 2, the search target data 54a shown in Fig. 13 is identified. When the search condition character string is "A prefecture, B city, C town 187" as shown in Fig. 4, the search target data 54b shown in Fig. 14 is identified.

[0063] In this embodiment, for example, the determination unit 42 determines whether the land master data including the land master land name land number data satisfying the search conditions is land master data of a land that cannot be confirmed on site. Here, the determination unit 42 may determine whether the land master data associated with the search target data 54 identified by the search unit 40 is land master data of a land that cannot be confirmed on site. For example, if the value of the land that cannot be confirmed on site flag included in the identified search target data 54 is 1, it is determined that the land master data associated with the search target data 54 is land master data of a land that cannot be confirmed on site. Also, if the value of the land that cannot be confirmed on site flag included in the identified search target data 54 is 0, it is determined that the land master data associated with the search target data 54 is not land master data of a land that cannot be confirmed on site.

[0064] For example, when the search target data 54a shown in Fig. 13 is identified, it is determined that the land master data associated with the search target data 54a is not land master data of an unconfirmable land. When the search target data 54b shown in Fig. 14 is identified, it is determined that the land master data associated with the search target data 54b is land master data of an unconfirmable land.

[0065] In this embodiment, for example, the map image generating unit 44 generates the map image 26 according to the identified search target data 54 .

[0066] In this embodiment, the map image output unit 46 outputs, for example, the map image 26 generated by the map image generating unit 44 .

[0067] Here, it is assumed that there is civil data including civil land name and land number data that meets the search conditions. In this case, as shown in Fig. 3, a map image 26a in which the polygon P1 indicated by the civil polygon data included in the civil data is identified and displayed may be generated and output. Note that this case corresponds to a case in which the land master data associated with the identified search target data 54 is not land master data for a land that cannot be confirmed on site.

[0068] Also, assume that there is no civil data including civil land name and land number data that satisfies the search conditions determined based on the search condition character string, but there is land master data including land master land name and land number data that satisfies the search conditions.

[0069] In this case, a map image 26 is generated and output in which a polygon indicated by the civil polygon data, which includes the land represented by the polygon indicated by the land master polygon data included in the land master data, is identified. Here, as shown in FIG. 5, a map image 26b may be generated and output in which a polygon P2 indicated by the land master polygon data included in the land master data and a polygon P3 indicated by the civil polygon data, which includes the polygon, are identified. Alternatively, a map image 26 in which the polygon P2 is identified without the polygon P3 being identified may be generated and output. Note that this case corresponds to a case in which the land master data associated with the identified search target data 54 is land master data of a land that cannot be confirmed on site.

[0070] An example of the flow of processing performed in the on-site inspection system 10 according to this embodiment will be described below with reference to the flow diagram shown in FIG.

[0071] First, the search condition character string receiving unit 38 receives a search condition character string (S101).

[0072] Then, the search unit 40 identifies the search target data 54 that satisfies the search condition determined based on the search condition character string received in the process shown in S101 (S102).

[0073] Then, the determination unit 42 checks the value of the on-site unconfirmable location flag included in the search target data 54 identified in the process shown in S102 (S103).

[0074] When the value of the unconfirmable land flag is 1, the map image generating unit 44 generates the map image 26 based on the civil data and the land master data (S104).

[0075] In the process shown in S104, for example, a map image 26 is generated, which is an image of a map attached to a registry office, in which a polygon identified by a land master polygon ID included in the search target data 54 specified in the process shown in S102 is drawn and the polygon identified by the civil polygon ID included in the search target data 54 specified in the process shown in S102 is drawn and the polygon identified by the civil polygon ID included in the search target data 54 is displayed in an identified manner. For example, as shown in Fig. 5, a map image 26b is generated, which is an image of a map attached to a registry office, in which a polygon P2 is drawn and a polygon P2 and a polygon P3 are displayed in an identified manner. The map image 26b is the map image 26 in which a polygon indicated by the civil polygon data that encompasses the land represented by the polygon indicated by the land master polygon data included in the land master data is displayed in an identified manner.

[0076] If the value of the unconfirmable land flag is 0, the map image generating unit 44 generates a map image 26 based on the civil data (S105). In the process shown in S105, for example, a map image 26 is generated which is an image of a map attached to a registry office on which a polygon identified by a civil polygon ID included in the search target data 54 specified in the process shown in S102 is displayed with distinction. For example, as shown in FIG. 3, a map image 26a is generated which is an image of a map attached to a registry office on which a polygon P1 is displayed with distinction. The map image 26a is the map image 26 on which a polygon indicated by civil polygon data included in the civil data is displayed with distinction.

[0077] Then, the map image output unit 46 outputs and displays the map image 26 generated in the process shown in S104 or S105 on the output unit 10d (S106), and the process shown in this processing example is terminated.

[0078] As described above, in the process shown in Figure 15, when a search hits a site that cannot be confirmed on site, by using the search target data 54, spatial calculations are not performed in the processes shown in S101 to S106, and a map image 26 in which the polygons indicated by the civil polygon data and the polygons indicated by the land master polygon data are distinguished and displayed is output.

[0079] In this embodiment, as described below, a drawing showing the location and shape of an enclosed plot may be used to confirm the location and shape of the enclosed plot without using the search target data 54.

[0080] FIG. 16 is a functional block diagram showing an example of functions implemented in the on-site inspection system 10 according to the modified example of this embodiment. The on-site inspection system 10 according to this modified example functionally includes, for example, a civil data storage unit 30, a land master data storage unit 32, a search condition character string reception unit 38, a map image generation unit 44, a map image output unit 46, a civil data search unit 60, and a land master data search unit 62. The civil data storage unit 30 and the land master data storage unit 32 are mainly implemented in the storage unit 10b. The search condition character string reception unit 38 is mainly implemented in the processor 10a and the input unit 10e. The map image generation unit 44, the civil data search unit 60, and the land master data search unit 62 are mainly implemented in the processor 10a. The map image output unit 46 is mainly implemented in the processor 10a and the output unit 10d.

[0081] The functions of the civil data storage unit 30, the land master data storage unit 32, the search condition character string reception unit 38, and the map image output unit 46 are similar to those described with reference to FIG. 6, and therefore description thereof will be omitted.

[0082] In this modified example, the civil data search unit 60 searches for civil data including civil place name and lot number data that satisfies a search condition determined based on a search condition string received by the search condition string receiving unit 38, for example.

[0083] In this modified example, for example, when there is no civil data containing civil place name and land number data that satisfies the search conditions determined based on the search condition string accepted by the search condition string accepting unit 38, the land master data search unit 62 searches for land master data containing land master place name and land number data that satisfies the search conditions.

[0084] In this modified example, for example, when there is land master data that is found in a search of land master data that is performed when there is no civil data containing civil land name and address data that satisfies the search conditions, the map image generation unit 44 generates a map image 26 in which the polygon indicated by the civil polygon data that encompasses the land represented by the polygon indicated by the land master polygon data included in the land master data is identified.

[0085] An example of the flow of processing performed in the on-site inspection system 10 according to this modified example will be described below with reference to the flow diagram shown in FIG.

[0086] First, the search condition character string receiving unit 38 receives a search condition character string (S201).

[0087] Then, the civil data search unit 60 searches for civil data that satisfies the search condition determined based on the search condition character string received in the process shown in S201 (S202).

[0088] Then, the land master data search unit 62 determines whether the search in the process shown in S202 has resulted in a hit, i.e., whether civil data has been identified that satisfies the search conditions determined based on the search condition string received in the process shown in S201 (S203).

[0089] If there is a hit (S203: Y), the map image generating unit 44 generates a map image 26 based on the civil data (S204). In the process shown in S204, for example, a map image 26 is generated, which is an image of a map attached to a registry office on which a polygon identified by a civil polygon ID included in the civil data specified in the process shown in S203 is displayed with identification. For example, as shown in Fig. 3, a map image 26a is generated, which is an image of a map attached to a registry office on which polygon P1 is displayed with identification. The map image 26a is the map image 26 on which a polygon indicated by civil polygon data included in the civil data is displayed with identification.

[0090] If there is no hit (S203: N), the land master data search unit 62 searches for land master data that satisfies the search conditions determined based on the search condition character string received in the process shown in S201 (S205).

[0091] Then, the map image generating unit 44 generates a map image 26 based on the civil data and the land master data (S206). In the process shown in S206, for example, a map image 26 is generated, which is an image of a registry office-mounted map in which a polygon identified by the land master polygon ID included in the land master data specified in the process shown in S205 is drawn and a polygon indicated by the civil polygon data that includes the land represented by the polygon is displayed in an identified manner. For example, as shown in FIG. 5, a map image 26b is generated, which is an image of a registry office-mounted map in which a polygon P2 is drawn and a polygon P2 and a polygon P3 are displayed in an identified manner. The map image 26b is the map image 26 in which a polygon indicated by the civil polygon data that includes the land represented by the polygon indicated by the land master polygon data included in the land master data is displayed in an identified manner.

[0092] In the process shown in S206, for example, a spatial operation may be performed to identify a polygon indicated by civil polygon data that encompasses the land represented by a polygon identified by a land master polygon ID included in the land master data identified in the process shown in S205.

[0093] Alternatively, polygon correspondence data in which the land master polygon ID is associated with the civil polygon ID of a polygon indicated by the civil polygon data and which includes the land indicated by the polygon identified by the land master polygon ID may be stored in advance in the map image generating unit 44. Then, based on the polygon correspondence data, a polygon indicated by the civil polygon data and which includes the land indicated by the polygon identified by the land master polygon ID included in the land master data specified in the process shown in S205 may be specified.

[0094] Then, the map image output unit 46 outputs and displays the map image 26 generated in the process shown in S204 or S206 on the output unit 10d (S207), and the process shown in this processing example is terminated.

[0095] In this embodiment, as described above, when there is no civil data including civil place name and place number data satisfying the search conditions, but there is land master data including land master place name and place number data satisfying the search conditions, a map image 26 is output in which the polygon indicated by the civil polygon data that encompasses the land indicated by the polygon indicated by the land master polygon data included in the land master data is identified. In this way, according to this embodiment, even if the searched land is an area that cannot be confirmed on the spot, that is, even if the drawing showing the location and shape of the searched land is closed, the location and shape of the land can be confirmed.

[0096] In this embodiment, the display mode of the polygons to be distinguished is not particularly limited. For example, the polygons may be distinguished by color or pattern (hatching). For example, the polygons P1 shown in Fig. 3, the polygons P2 shown in Fig. 5, and the polygons P3 shown in Fig. 5 may have different colors. Also, the polygons P1 shown in Fig. 3, the polygons P2 shown in Fig. 5, and the polygons P3 shown in Fig. 5 may have different patterns.

[0097] Furthermore, the display mode of a polygon that is distinctively displayed may differ depending on whether the land it represents is an area that cannot be confirmed on the spot. For example, the display mode of a polygon representing an area that cannot be confirmed on the spot may differ from the display mode of a polygon representing an area that is not an area that cannot be confirmed on the spot. That is, the display mode of polygon P1 shown in Figure 3 may differ from the display mode of polygon P3 shown in Figure 5. Furthermore, the display mode of polygon P1 shown in Figure 3 may differ from the display mode of polygon P2 shown in Figure 5.

[0098] Furthermore, the display mode of polygons indicated by the land master polygon data and the display mode of polygons indicated by the civil polygon data may be different. For example, the display mode of polygon P2 shown in Fig. 5 may be different from the display mode of polygon P3 shown in Fig. 5. In this case, the display mode of polygon P1 shown in Fig. 3 and the display mode of polygon P3 shown in Fig. 5 may be the same.

[0099] The display mode of the polygon P1 shown in Fig. 3 may be the same as the display mode of the polygon P2 shown in Fig. 5. Also, the display mode of the polygon P2 shown in Fig. 5 may be the same as the display mode of the polygon P3 shown in Fig. 5.

[0100] In this embodiment, for example, the user may perform an operation to specify a position on the map image 26, and thereby the land registration information associated with a polygon including that position may be output. The user may perform an operation to specify a position on the displayed map image 26, and thereby the polygon including that position and indicated by the civil polygon data may be specified. Then, the land registration information for all of the lands included in the specified polygon may be output.

[0101] It should be noted that the present invention is not limited to the above-described embodiment.

[0102] In addition, the specific character strings and numerical values ​​described above, as well as the specific character strings in the drawings, are merely examples. It is not limited to these character strings and numbers. [Explanation of symbols]
