Information processing is performed based on the information received and output to the display unit 308 is performed.

Next, with reference to the flowchart shown in FIG. 4, the procedure of the information providing method executed by the information providing device 300 configured as described above will be described by taking as an example the case of providing the land registration information.

In step S402, the user operates the information providing device 300 to acquire location information regarding a desired land from the Internet 106. The location information is information necessary for requesting registration information from the registration information server 104 and for requesting map data from the map information server 102, and can be, for example, an address. For example, if the land for which registration information is desired is owned by a company, the browser software is executed on the information providing device 300 to access the website of the company provided by the service provider on the Internet 106. do. Then, the information of the address included in the website of the company displayed on the information providing device 300 is acquired.

In step S404, the user operates the information providing device 300 to access the registration information server 104. The registration information server 104 causes the display unit 308 of the information providing device 300 to display a screen including an input area for inputting information necessary for providing registration information. The user inputs the location information of the land acquired in step S402 in the input area in the displayed screen. The input land location information is transmitted from the information providing device 300 to the registration information server 104. The registration information server 104 reads the registration information corresponding to the received location information from the registration information database 105 and transmits it to the information providing device 300. In this way, the information providing device 300 acquires the registration information.

Next, in step S406, predetermined data is extracted from the acquired registration information data. The information processing unit 310 of the information providing device 300 acquires the coordinates of the boundary point of the land based on the data extracted from the acquired registration information. Next, in step S408, the information providing device 300 acquires the origin of the plane orthogonal coordinate system based on the acquired registration information.

Next, in step S412, the data acquisition unit 304 of the information providing device 300 accesses the map information server 102. Then, the location information of the land acquired in step S402 is transmitted, and the map data corresponding to the location information is requested. In response to the received request, the map information server 102 reads the map data corresponding to the location information included in the request from the map database 103 and transmits the map data to the information providing device 300. The information providing device 300 displays the acquired map data on the display unit 308, and also performs a process of drawing the indication of the position of the latitude and longitude converted in step S410 on the map.

The information processing executed in each step after step S406 is performed by extracting predetermined data from the acquired registration information data. Hereinafter, these information processing will be described in detail.

[Data extraction process]
The registration information data is image data obtained from information written on a paper medium, and includes the following files.

(1) Map The map includes information corresponding to "a map or a drawing equivalent to a map" among the real estate registration items required to be announced by the Real Estate Registration Law. That is, the map is the information of the map of Article 14, Paragraph 1 of the Real Estate Registration Law or the drawing (so-called official map) conforming to the map of Article 14, Paragraph 4 of the same Article.
(2) Owner matters The owner matters include information on the name or name and address of the current owner among the registered items of the real estate.
(3) Land drawing The land drawing includes the land survey map among the registered items of real estate. A land survey map is a drawing that clarifies the results of a survey on the land area of a single stroke. The registration information provided by the registration information providing service includes the owner's information associated with the address and the land area survey map. The land survey map is an official survey map defined by the Real Estate Registration Law, and includes a legend such as the lot number associated with the address, the type of boundary marker and the reference point, and the coordinate cayley table. The lot number is a management number set by the Legal Affairs Bureau for each section of land, and is a number assigned to each land in the register. The coordinate quadrature table shows the area calculation method and the calculation result.
(4) All land matters The all land matters include information on all the registered items of real estate.

In the data extraction in step S406, predetermined data is extracted by (3) OCR (Optical character recognition) analysis from the image of the land survey map included in the land drawing.

FIG. 5 shows an example of a geological survey map. As shown in the figure, the geological survey map of the registration information includes a plurality of coordinate quadrature tables 502a to 502c. Each table is associated with a "lot number" in the upper right corner of the drawing. A particular "lot number" coordinate quadrature table can span multiple pages. The land boundary points are extracted from the numerical values contained in _{the "X n} " and "Y _{n" columns of these coordinate quadrature tables. The information providing device 300 identifies the character strings of "X n} " and "Y _n " included in the coordinate product table, recognizes the character strings located below the character strings, and thereby recognizes each coordinate (X _n). , Y _n ) get the information. Each coordinate (X _n , Y _n ) is associated with a "station" and uniquely identifies a geographic location.

[Get image of coordinate quadrature table]
In order to perform OCR analysis of the coordinate quadrature table, it is first necessary to extract all the coordinate quadrature tables as images. To properly extract the coordinate Cayley Table, enlarge the table area to be extracted and capture an image of the area by running screenshot software. Then, by executing the OCR analysis software, the image of the coordinate quadrature table can be extracted.

When identifying the area of the coordinate quadrature table and extracting the image, it is determined whether or not it is an appropriate area using the following criteria.
-The first line of the image _{contains the strings "Sokuten", "X n} ", "Y _n ", "(X _{n + 1} −X _n-1 ) Y _n " and "Distance". There is.
-The first line of the image should not be the line that starts with the character string "lot number".
-The last line of the image contains _{information for all fields of "Sokuten", "X n} ", "Y _n ", "(X _{n + 1-} X _n-1 ) Y _n ", and "Distance". include.
-The last line of the image does not include the line containing the character string "double area", "area", or "land area".

FIG. 6 shows an example in which the image of the coordinate quadrature table 502a is extracted from the coordinate quadrature table extracted from the image by the above procedure. The coordinate quadrature tables 502b and 502c are also extracted in the same manner.

[OCR analysis of coordinate quadrature table]
Next, by executing the OCR analysis software, a text-based table is generated for the image of the coordinate quadrature table acquired above. Hereinafter, this table is referred to as a boundary point data table.

The boundary data table must always contain the following fields, which must be the only ones:

In the present embodiment, the following criteria are used in determining whether the table extracted from the coordinate quadrature table is an appropriate boundary point data table.
-Each row has 5 columns, and there are _{5 headers: "Sokuten", "X n} ", "Y _n ", "(X _{n + 1-} X _n-1 ) Y _n ", and "Distance".
-Every line has 5 elements, no empty elements.
• The values in each column are either left-aligned or right-aligned.
The column "1" can include uppercase letters ("[AZ]"), hyphens "-", and numbers ([[0-9] +]).
-If a hyphen "-" is present in column "1", the character immediately preceding it must be in uppercase ([AZ]) and the number immediately following it must be present.
-Columns "2, 3" optionally include a "-" at the beginning, which requires a "." And three numbers after it.
-Column "5" is positive. It must not contain a "-" and must have a "." Followed by three digits.
-Column "4" optionally contains a "-" at the beginning, which requires a "." And six numbers after it.

In one embodiment, when the boundary point data table is generated, the structural data is Javascript Object Notation (JSON) data, which is a standard text-based structural data representation format based on the notation of Javascript structural data objects. May be used.

In one embodiment, the data acquired by performing the OCR analysis may be further cleaned by correcting misrecognized characters. In this cleaning, for example, when Xn is erroneously recognized as χ (chi) n, a process such as correcting it to X is performed. The cleaned data is then checked for errors against the criteria described above. As a result, a boundary point table reconstructed from the image of the coordinate quadrature table is generated as shown in FIG. In this way, it is possible to acquire JSON data including phrases, words, and their boundary boxes detected from the coordinate quadrature table.

[Obtaining the origin of the plane orthogonal coordinate system]
The coordinate quadrature table is a table in which boundary points, reference points, etc. are displayed with reference to a universal coordinate system. Since the revision of the Survey Law in 2002, the world geodetic system has been used as the coordinate system of the geodetic survey map. Here, the position of the origin of the plane rectangular coordinate system in the land survey differs depending on the area to which the survey is applied. A system number is assigned to each applicable area. The relationship between the system number based on the survey method and the plane orthogonal coordinate system is specified, for example, on the site of the Geographical Survey Institute. As an example, information on the plane orthogonal coordinate system for system numbers I and II is shown in the table below.

In step S408, the information providing device 300 accesses the site of the Geographical Survey Institute, determines the applicable area corresponding to the target address from the table of the plane orthogonal coordinate system, and determines the applicable area corresponding to the applicable area, and the origin of the coordinate system corresponding to the applicable area. Get latitude / longitude information. Specifically, the character string included in the target address is matched with the character string of the applicable area in the table of the plane orthogonal coordinate system, and the latitude and longitude information corresponding to the applicable area including the matched character string is acquired. ..

In another embodiment, the information providing device 300 stores a table of the plane orthogonal coordinate system in the storage unit 306 in advance, and determines the applicable area corresponding to the target address from the table stored in the storage unit 306. Then, the latitude and longitude information of the origin corresponding to the applicable area is acquired.
Further, unlike the example shown in FIG. 5, the system number may be described as "World Geodetic System (II)" at the lower right of the geodetic survey map. Therefore, in step S408, the information providing device 300 acquires the system number by analyzing the information of the standard method described in the lower right of the geological survey map, and obtains the acquired system number from the table of the plane rectangular coordinate system. The coordinates of the corresponding origin may be specified.

Further, in step S408, the information providing device 300 analyzes the information of the standard method described in the lower right of the geological survey map and tries to acquire the system number, and becomes a target when the system number cannot be acquired. It may be configured to acquire the latitude and longitude information of the origin based on the address.

The standard methods for defining the position of the origin include the "Japanese geodetic system" and the "world geodetic system". In the example shown in FIG. 5, it is described in the lower right that the standard method of the geodetic survey map is the world geodetic system. Therefore, in step S410, the information providing device 300 determines whether it is the "Japanese geodetic system" or the "world geodetic system" by analyzing the information of the standard method described in the lower right of the geodetic survey map. It may be configured to acquire information on the origin according to the standard method from the site of the Geographical Survey Institute.

Alternatively, the standard method corresponding to the time shown in the geological survey map may be determined. For example, in the geological survey map, the "creation date" and the "coordinate system number" or "number" are described, so by recognizing this character information, it is adopted at the time of the "creation date". The standard method may be determined, and the origin information (table of plane rectangular coordinates) corresponding to the determined standard method may be acquired by using the "coordinate system number" or the "number".

In addition, when acquiring the origin information, after accessing the information of either "Japanese geodetic system" or "World geodetic system" to acquire the origin information, one standard method is changed to the other standard method. The coordinate conversion process of the above may be performed to acquire the information of the origin according to the recognized standard method. In addition, the information of the origin corresponding to the "Japanese geodetic system" and the "world geodetic system" is stored in the information providing device 300 in advance, and the information of the origin corresponding to the recognized standard method is acquired. May be good. Further, the information of either the "Japanese geodetic system" or the "world geodetic system" is stored in the information providing device 300 in advance, and after acquiring the information of the origin according to the recognized standard method, the one standard method is used. It is also possible to perform coordinate conversion processing from to the other standard method to acquire information on the origin corresponding to the recognized standard method.

[Plot of latitude / longitude information]
The boundary point table generated as shown in FIG. 7 contains station information, X _n , Y _n , (X _{n + 1} −X _n-1 ) Y _n , and distance information in each row in order from the left. ing. The information processing unit 310 of the information providing device 300 acquires the information of the _{coordinates (X n} , Y _{n) from each row of the boundary point table.} Next, this coordinate is converted into latitude / longitude information based on the origin information acquired in step S410. Next, data for displaying a map image is generated based on the information of the converted set of latitude and longitude. In the present embodiment, as data for displaying a map image, KML (Keyhole Markup Language) data in which information for the purpose of managing the display of three-dimensional geospatial information in an application program is described in XML is generated.

In step S412, the data acquisition unit 304 of the information providing device 300 accesses the map information server 102. Next, the location information of the land acquired in step S402 is transmitted, and the map data corresponding to the location information is requested from the map information server 102. In response to the received request, the map information server 102 reads the map data corresponding to the location information included in the request from the map database 103 and transmits the map data to the information providing device 300. The information providing device 300 displays the acquired map data on the display unit 308, and based on the KML data converted in step S410, indicates the position corresponding to the latitude and longitude of the station on the map. Performs the process of plotting at the position of.

FIG. 8 shows an example of an image in which positions corresponding to latitude and longitude are plotted on a map. A plurality of points 802 aligned in FIG. 8 indicate latitude / longitude information. In the example shown in the figure, round points are used as markings, but the markings are not limited to round points, and polygons such as triangles and quadrangles and various other figures may be used. The information providing device 300 may be configured so that these various markings can be selected by the user.

In one embodiment, a line passing through a plurality of displayed stations may be displayed on the map. In this case, various line types such as dotted lines and arrows may be used as the line types.

In one embodiment, the area surrounded by the station on the map may be represented by hatching. As an alternative, the image of the map behind the figure may be transparently displayed by superimposing and displaying the figure in which the area surrounded by the station is colored with a semi-transparent color on the map.

In one embodiment, when the land described in the registration information is divided into a plurality of lands, the type of marking and the display mode thereof may be changed for each of the divided lands. For example, different colored markings may be used for each divided land.

According to the information providing method according to the present embodiment described above, the station of the registered land can be visually grasped on the map. In addition, by drawing the survey points directly using the information of the land survey map included in the registration information, it is possible to grasp more accurate land information and information around the land.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various other modifications and modifications can be made. Further, it goes without saying that the plurality of embodiments described above can be used in combination of two or more of each embodiment as appropriate.
