Description

  The present invention relates to a land area check program, a land area check method, and a land area check apparatus for checking whether or not the area of a land in a brush unit described in a register matches an actual area of land.

  Rights related to land are recorded in the register (Articles 3 and 11 of the Real Estate Registration Act [enforced at the time of filing this application; the same shall apply hereafter)] and publicly announced (Article 177 of the Civil Code). In the title part of the register, the land area, that is, the area of the land, is described as an entry for the registered registration (Article 34, Item 1, Item 4 of the Real Estate Registration Act).

  As a result of the amendment of the Real Estate Registration Act in 2004, the register is basically a record that is adjusted with a magnetic disk (Article 2.5, 9 of the Real Estate Registration Act). In the agency or online agency, it is possible to browse the registry (registration record) and apply for a copy using a computer system (electronic information processing organization).

JP 2004-355176 A

  The land registration described above does not establish the scope of ownership of land, but there is a situation in which property taxes are evaluated based on this. For this reason, when the registration system started, there were many cases where the area of own land was underreported. In addition, with the surveying technology at that time, it was difficult to accurately measure the land area. Therefore, the description of the land area in the old land register used at that time did not necessarily match the actual land area, and it was transferred to the current register (registered record) as it is, so even now. The land area described in the registration book (registration record) does not necessarily match the actual land area.

  However, as mentioned above, if the property tax amount is evaluated based on the description of the land area on the register, if the incorrect land area description is left unattended, the fairness of the tax burden cannot be maintained. The property tax capture rate by the state remains low. In addition, if the purchase and sale of land is “public sale” based on the land area on the registry, the buyer who has trusted the description of the land area on the registry and the person who intends to receive the setting of a security interest (mortgage, etc.) There is also the possibility of suffering unexpected damage. For example, if the actual land area is smaller than the land area on the registry, the planned building cannot be built.

  In this regard, according to the geodetic survey map introduced by the real estate registration rule revision in 1960, the surveying point is new and its accuracy is legally secured. It is possible to judge the accuracy of the land area on the registration record.

However, such a land survey map is created only for the land (brush) that has been divided after the above revision and newly registered land (brush), so the land survey map is provided for all land (brushes). It is not translated. Moreover, since the geodetic survey maps created before the Showa 50s include inaccurate ones, it is not possible to trust all the geodetic survey maps.

  Therefore, the problem with this proposal is whether or not the land area on the registry (registration record) is correct even if there is no land survey map for the land (brush) to be surveyed or the reliability is low. It is to make the determination possible.

  In this plan, first, referring to the register stored in the storage means, the area of the brush of the determination target is acquired, and whether or not there is a land surveying map in which the description of the area is accurate for the determination target brush. Determine. Then, when there is no land area survey map in which the description of the ground area is accurate for the determination target brush, the determination target brush is based on the registered map that displays the determination target brush stored in the storage means. All brushes belonging to the same brush group are identified, and as long as there is a geodetic survey map that accurately describes the ground area for all brushes other than the target brush belonging to the brush group, Comparing the total of the land area obtained from the register for the brush with the area of the block corresponding to the brush group calculated based on the house map stored in the storage means, the difference between the two is within the reference value If so, it is determined that the land area obtained from the registry for the determination target brush is correct.

  According to this plan configured as described above, the land area on the registry (registration record) is correct even if there is no land survey map for the surveyed land (brush) or the reliability is low. It is possible to determine whether or not.

Hereinafter, embodiments of the present plan will be described based on the drawings.
<System configuration>
FIG. 1 is a block diagram showing a schematic configuration of an electronic information processing organization (computer system) installed in a computer agency. As shown in FIG. 1, this electronic information processing organization is a book in which a registration record as a registration book is recorded, and a magnetic disk (a thing that can record certain items reliably by a method equivalent thereto). The same applies to the following.) The server apparatus 1 that holds the adjusted contents at 10 and accesses (reads and writes) the registration record can communicate with the server apparatus 1 through a LAN (local area network). And a plurality of terminals 2 (only one is shown in FIG. 1).

  The server device 1 constitutes a server & client system together with the terminals 2 and has a normal hardware configuration required for the server device 1. That is, the server device 1 includes a magnetic disk 10, a CPU 11, a communication adapter 12, a display 13, an input device 14, a RAM 15, and the like that are connected to each other through a bus B.

  Among these, the CPU 11 is a processing device (computer) that reads a program from the magnetic disk 10 and executes processing according to the program.

The communication adapter 12 is a device that manages a communication protocol with the terminal 2 by terminating the LAN.

  The display 13 is a display device that displays a screen as a processing result of the CPU 11.

  The input device 14 is a keyboard, a pointing device, or the like for inputting various commands to the CPU 11.

  The RAM 15 is a main storage device in which a work area by the CPU 11 is expanded. When the CPU 11 executes a land area check program which will be described later, a first save area 151 and a second save area 152 which will be described later are constructed. .

  The magnetic disk 10 is a storage means such as a hard disk, but may be a magneto-optical disk or a semiconductor memory as long as it is a nonvolatile and large-capacity storage medium. In FIG. 1, the drawing is made as if the disk device is one, but the magnetic disk 10 may be composed of a plurality of devices or distributed over a plurality of server devices existing on the network. It may be arranged.

  The magnetic disk 10 stores various programs 110 and various data read and executed by the CPU 11.

The various data stored on the magnetic disk 10 include a map attribute table 111, a land surveying pen and paint attribute table 112, a map graphic coordinate value table 113, a ground surveying figure graphic coordinate value table 114, a ground surveying figure graphic connection table 115, A house map coordinate value table 116, a house map figure connection table 117, a registry area determination result table 118, a registration information table 119, a map figure attribute table 120, and a map figure connection table 121 are included.

Among these, the registration information table 119 is a registration book provided in the computer agency. The unit of land registration in the register is called “brush”, which does not necessarily coincide with the scope of ownership and does not coincide with the real estate land. Therefore, in order to clarify the concept, in the following description, the notation of the unit of land to be checked for land area according to the present embodiment is unified as “brush”. As described above, since the registration information table 119 is the registration book itself, as shown in FIG. 2, the registration information table 119 includes, for each writing brush in the area under the jurisdiction of the computer agency, Contains records to store registration records. That is, each record includes a plurality of fields for recording each entry included in the registration record for each brush (in FIG. 2, the “land number” in which the lot number of each brush is recorded. ”Field, the“ registration date ”field in which the registration date is recorded, and the“ area ”field in which the land area is recorded are illustrated, and other fields for the entry items are omitted, but other Each record also includes a field in which a registration item constituting the title part and a registration item constituting the right part are recorded).

In addition, the map brush attribute table 111 is a table for registering related information about each registration information included in the registration information table 119. As shown in FIG. Field number, place number, and date of registration (these are also included in the entry), a map showing the area containing the writing brush (so-called registry office under Article 14, Paragraph 1 of the Real Estate Registration Act) Records that include the “Map Drawing No.” field in which the identification number of the attached map) is recorded, the “Surface Surveying Map Number” field in which the identification number is recorded when there is a ground survey map for the brush, Have.

Next, the map graphic attribute table 120, the map graphic connection table 121, and the map graphic coordinate value table 113 are a table group in which the contents of an electronic registry office-equipped map are registered. That is, in the map graphic attribute table 120, as shown in FIG. 4, for each brush, a “map drawing No.” field in which the identification number of the registration office map displaying the brush is recorded, A record including a “land area” field or the like in which the area of the brush (the area on the register) is recorded is included. Although illustration is omitted, registered items such as a texture are also registered in each record of the map graphic attribute table 120. Moreover, in the map figure connection table 121, as shown in FIG. 5, for each place number, each side of the brush stroke line corresponding to the place number (when the shape of the brush is represented by a polygon [approximate] Is defined by a set of identification symbols (point number 1, point number 2) of both end points. Further, as shown in FIG. 6, the coordinate values of the points registered in the map graphic connection table 121 are registered in the map graphic coordinate value table 113.

  Next, the geodetic survey map attribute table 112, the geodetic survey map figure connection table 115, and the geodetic survey map figure coordinate value table 114 are tables in which the contents of the digitized geodetic survey map are registered. In other words, as shown in FIG. 7, in the geodetic survey map attribute table 112, a “lot number” field in which the lot number of the corresponding brush is recorded and an identification number of the geodetic survey map are recorded for each of the geodetic survey maps. A record including a “land area survey number” field, a “land area” field in which an area obtained by surveying the brush is recorded, and the like are included. Moreover, in the geodetic survey figure figure connection table 115, as shown in FIG. 8, each side of the area survey map, each side of the stroke boundary line on the geodetic survey map (the shape of the brush is represented by a polygon [approximate] Each side in the case) is defined by a set of identification symbols (point number 1, point number 2) of both end points. Further, as shown in FIG. 9, coordinate values of each point registered in the ground surveying figure graphic connection table 115 are registered in the ground surveying figure graphic coordinate value table 114.

Next, the house map coordinate value table 116 and the house map connection table 117 are tables for registering the contents of the digitized house map. Here, the housing map is a map that shows the position of the housing land (the housing land specified by the house number of the housing display) that is actually partitioned for housing, and is created based on the satellite photograph. Therefore, although the position of the boundary line between the road and the residential land is accurate, the boundary line between the residential land is not necessarily coincident with the boundary between the brushes (writing boundary) on the register. Therefore, it is difficult to accurately calculate the area of the brush based on the residence map, but the area of the entire block corresponding to the group of brushes surrounded by the road on the registry (on the registry map) It can be calculated accurately. Therefore, the house map is also digitized and registered in the house map coordinate value table 116 and the house map connection table 117. Then, in the housing map connection table 117, as shown in FIG. 10, for each housing land specified by the house number of the housing display, each side constituting the outer edge (the shape of the housing land is represented by a polygon [approximate]). Each side in the case) is defined by a set of identification symbols (point number 1, point number 2) of both end points. Moreover, as shown in FIG. 11, the coordinate value of each point registered in the house map connection table 117 is registered in the house map coordinate value table 116.

  Next, in the register area determination result table 118, for each writing brush, a geodetic survey map is registered in the geodetic survey map attribute table 112, the geodetic survey map figure connection table 115, and the geodetic survey map figure coordinate value table 114. Is registered with an evaluation of its accuracy, and an assumed error in the land area on the registry registered in the registration information table 119 (an error from the actual area assumed based on the area on the house map) Is a registered table (corresponding to a determination result table). Therefore, in the registry area determination result table 118, for each brush, a “lot number” field in which a lot number is recorded, a “division survey map number” field in which an identification number of the corresponding land survey map is recorded, and the same land survey The “creator” field in which the identification information of the producer of the figure is recorded, the “date of creation” field in which the date of creation of the same area survey map is recorded, and the number of corners of the brush shape (ie “Number of point numbers registered in the geodetic survey figure figure connection table 115” field, the length of the border line surrounding the brush (that is, the area survey figure figure connection table 115 for the brush) The “peripheral length” field in which the total length of the connection connecting a plurality of points indicated by the registered point numbers is recorded, and the area (land volume) registered in the ground surveying pen attribute table 112 for the land surveying map Has a record consisting of a “judgment result” field in which an evaluation result as to whether or not is correct is recorded, and an “assumed error” field in which an assumption error about the land area of the brush is recorded. Yes.

  The various programs 110 stored on the magnetic disk 10 include basic programs and server programs, programs that update the contents of the tables 111 to 121 based on operations by the registrar, and operations by general viewers. A program for updating the post-registration area determination result table 118 with reference to the tables 111 to 117 and 119 to 121 and outputting the contents (a ground check program to be described later) is included.

  The terminal 2 is a terminal installed at the desk or reading room of each registrar in the Computer Agency, and is a computer that constitutes a server & client system with the server device 1. Therefore, it is equipped with normal hardware (CPU 21, display 22, input device 23, hard disk 24, communication adapter 25, etc.) and software (basic program, client program) as a client computer, and is input using the input device 23. In addition, the command for the land area check program can be transmitted to the server 1, and as a result, the screen responded from the server 1 can be displayed on the display 22.

Note that the client function of the terminal 2 may be provided in the server 1 itself. That is, the various programs 110 stored in the magnetic disk 10 of the server 1 are notified of the command input using the input device 14 to the above-mentioned land area check program, and a screen as a processing result by the land area check program is displayed on the display 13. A client program to be displayed above may be included.
<Processing content>
Next, processing executed by the CPU 11 of the server 1 in accordance with the land area check program will be described with reference to the flowcharts of FIGS. 13 and 14. This processing is performed by the CPU 11 in response to the start command having the lot number of the surveyed brush as a parameter input to the CPU 11 of the server 1 through the input device 14 of the server 1 or the input device 23 of the terminal 2. Start by loading the area check program from

  Then, in the first S01 after the start, the CPU 11 searches the map brush attribute table 111 based on the input lot number of the survey target brush and inputs the map drawing No. corresponding to the survey target brush. Is read out and recognized, and the same map drawing No. Read all lot numbers corresponding to.

  Subsequently, the CPU 11 compares the land area registered in the registration information table 119 with the land area on the land survey map for each of the lot numbers read in S01, in order to determine the error. The loop process of S14 is executed.

  In the first step S02 after entering this loop process, the CPU 11 specifies one unspecified one among the lot numbers read in S01 as a determination target lot number.

  In next S03, the CPU 11 refers to the register area determination result table 118, and whether or not there is a land survey map for the brush indicated by the determination target lot number, depending on whether or not the determination target lot number is registered. Check. Then, the CPU 11 advances the process to S04 when the corresponding land area survey map exists, and advances the process to S11 when the corresponding land area survey map does not exist.

  In S <b> 11, the CPU 11 determines that the land area on the registry is not reliable (×) for the determination target lot number.

  In next S 12, the CPU 11 stores the determination target lot number in the first save area 151 on the RAM 15 to be a target of the land area accuracy determination based on the house map with respect to the brush having no land area survey map.

  On the other hand, in S04, the CPU 11 refers to the register area determination result table 118, and the creation date of the geodetic survey map corresponding to the determination target lot number is created before the predetermined reference year. Check if it exists. This reference year is a year in which the accuracy of the geodetic survey map becomes reliable regardless of the producer, and is set in, for example, 1975. Then, the CPU 11 advances the process to S005 if the creation date is before the reference year, and advances the process to S08 if the creation date is after the reference year.

  In S05, the CPU 11 refers to the land surveying map attribute table 112 and reads the land area corresponding to the determination target lot number.

  In the next S06, the CPU 11 reads the land area corresponding to the determination target lot number with reference to the registration information table 119.

  In next S07, the CPU 11 compares the ground area read in S05 with the ground area read in S06, and checks whether the difference (or ratio) between the two is within a predetermined reference value. The CPU 11 advances the process to S08 if the difference (or ratio) between the two is within the predetermined reference value, and advances the process to S09 if the difference (or ratio) between the two exceeds the predetermined reference value. Proceed.

  In S08, the CPU 11 determines that the area on the registry is reliable (◯) for the determination target lot number.

  On the other hand, in S09, the CPU 11 determines that the land area on the registry is not reliable (×) for the determination target lot number.

  In the next S10, the CPU 11 stores the determination target lot number in the second save area 152 on the RAM 15 in order to perform the inspection in S15 because the accuracy of the geodetic survey map may be low.

  Executing the processes of S03 to S12 described above for the investigation target brush corresponds to a land area acquisition step, and the CPU 11 executing the process corresponds to a land area acquisition unit. In addition, when the processes of S05 to S10 are performed on other brushes, for a plurality of brushes having a ground surveying map, the difference between the ground area described in the ground surveying map and the land area acquired from the registry for the corresponding brush This corresponds to the step of determining whether or not the land area described in the land area survey map is correct depending on whether or not is within the reference value and registering the determination result in the determination result table together with the identification information of the producer.

  In S13 executed after the completion of the above-described S08, S10, or S12, the determination result in S08, S09, or S11 is used as the “determination result” field in the record corresponding to the determination target lot number in the registry area determination result table 118. (If the value has already been entered, it will be overwritten).

  In next S14, it is checked whether or not all the lot numbers extracted in S01 have been specified as the judgment target lot numbers in S02. If all the lot numbers have not yet been identified as determination target lot numbers, the CPU 11 returns the process to S02, identifies the next lot number as the determination target lot number, and executes the processing from S03 onward.

  On the other hand, as a result of repeating the loop processing of S02 to S14, when all the lot numbers extracted in S01 have been specified as determination target lot numbers, the CPU 11 advances the process from S14 to S15, The loop process of S15 to S19 is executed.

  This loop process is a process for determining the reliability of the lot number stored in the second save area 152 based on the reliability of the producer at the time of creation of the corresponding land survey map.

  In the first step S15 after entering this loop process, the CPU 11 extracts one determination target lot number from the second save area 152.

  In the next S16, the CPU 11 creates a land area created by the same producer from the register area determination result table 118 at the same time (for example, the same year, the same year, etc.) as the land area survey map corresponding to the determination target lot number. Extract records for survey maps. At this time, if there are many extracted records, by adding other items such as the number of corners and / or the peripheral length to the search condition, the extraction result is the land area corresponding to the judgment target lot number in these search condition items. You may narrow down to records that are common to the survey map. After that, the CPU 11 reads the value of the “determination result” field in each record extracted from the registry area determination result table 118. Then, the CPU 11 calculates the ratio of the number of records for which “◯” is set in the “determination” field to the total number of extracted records. If the calculated ratio is equal to or greater than the predetermined reference ratio, it is determined that the land area on the registry is reliable (◯) for the determination target lot number.

  In the next S17, only when the CPU 11 determines that the land area on the register is reliable (O) in S16, the “determination result” field of the record of the determination target lot number in the registration area determination table 118 Overwrite “○”.

In next S <b> 18, the CPU 11 deletes the determination target lot number from the second save area 152 only when it is determined in S <b> 16 that the land area on the registry is reliable (◯).

  The time of the processes of S15 to S19 described above for the investigation target brush corresponds to a land surveying map presence / absence determination step, and the CPU 11 executing such processing corresponds to a ground surveying map existence determination unit.

  In the next S19, it is checked whether or not all lot numbers stored in the second save area 152 have been extracted in S15. If it is determined that the lot numbers stored in the second save area 152 include those not yet extracted in S15, the CPU 11 returns the process to S15.

  On the other hand, when it is determined that all the lot numbers stored in the second save area 152 have been extracted in S15 as a result of repeating the loop process of S15 to S19, the CPU 11 performs the process. The process proceeds from S19 to S20, and the loop process of S20 to S31 is executed.

  This loop process is for determining the accuracy of the land area on the register based on the block area calculated from the house map for all lot numbers remaining in the first save area 151 and the second save area 152. It is processing.

  In the first step S20 after entering this loop process, the CPU 11 specifies one unspecified one of the lot numbers remaining in the first save area 151 and the second save area 152 as a determination target lot number. Then, the CPU 11 refers to the map figure connection table 121 and specifies the lot numbers of all brushes belonging to the same brush group as the brush of the determination target lot number (referred to as a group of brushes surrounded by a road). Specifically, the CPU 11 uses, as the lot numbers of the brushes adjacent to the brush corresponding to the determination target lot number, all lot numbers in which a part of the point numbers registered in the map figure connection table are common to the determination target lot number. Identify. Next, CPU11 specifies the lot number of the brush further adjacent with respect to the adjacent brush specified in this way. Thereafter, the CPU 11 repeats the above process until no adjacent brush lot number is found, thereby identifying all brush stroke numbers belonging to the same brush group as the determination target lot number. Then, the CPU 11 reads the ground area for the determination target lot number and the lot numbers of all the brush strokes belonging to the same brush group. At this time, the CPU 11 reads the land area from the registration information table 119 for the house numbers remaining in the retreat areas 151 and 152, and from the land surveying pen attribute table 112 for the other house numbers. Thereafter, the CPU 11 calculates the total value of the land area read for each brush.

  In the next S21, the CPU 11 calculates the area of a block (a block surrounded by the public road) that matches the brush group for which the total value of the land area is calculated in S20. For example, the CPU 11 reads the coordinate values of all points defining a series of connections forming the outer edge of the brush group based on the map figure coordinate value table 113 and the map figure connection table 121 and recognizes the positions of the series of connections. . Then, the positions of all the connections defined in the house map coordinate value table 116 and the house map figure connection table 117 are compared, and a series of connections closest to the outer edge of the brush group is specified. Based on the positions of the series of connections identified in this way (the coordinate values of all points defining each connection), the CPU 11 calculates the area of the block surrounded by the identified series of connections.

In next S22, the CPU 11 checks whether or not two or more lot numbers including the judgment target lot number remain in both the retreat areas 151 and 152 among the lot numbers of the brushes belonging to the brush group specified in S20. To do. If two or more lot numbers remain in either of the retreat areas 151 and 152, the CPU 11 can no longer obtain an accurate area for these lot numbers. Then, it is determined that the land area on the registry (registration information table 119) is not reliable (×), and in the next S26, it is determined that the “assumed error” is “unknown”. In S29, the CPU 11 registers (overwrites) the determination results in S25 and S26 in the record of the corresponding lot number in the registry area determination result table 118. In S30, the plurality of lot numbers are stored in the save areas 151, 151. Delete from 152.

  On the other hand, when it is determined in S22 that only the determination target lot number remains in both the retreat areas 151 and 152 among the brush lot numbers belonging to the brush group specified in S20, the CPU 11 performs S23. Then, the total value of the land area calculated in S20 is compared with the area calculated in S21, and it is checked whether or not the difference between the two is within a predetermined reference value. If the difference between the two is equal to or greater than the reference value, the CPU 11 determines that the land area on the register (registration information table 119) is unreliable (×) for the determination target lot number in S27, and the next S28 The “assumed error” is determined to be the difference calculated in S23 (the difference between the total value of the land area for the brush group and the area calculated from the house map). In S29, the CPU 11 registers (overwrites) the determination results in S27 and S28 in the record of the determination target lot number in the registry area determination result table 118. In S30, the determination target lot number is stored in each save area 151, Delete from 152.

  On the other hand, if it is determined in S23 that the area difference is within the reference value, the CPU 11 can trust the land area on the registration book (registration information table 119) for the determination target lot number in S24 ( ○). In step S29, the CPU 11 registers (overwrites) the determination result in step S24 in the record of the determination target lot number in the registry area determination result table 118. In step S30, the CPU 11 stores the determination target lot number from each of the save areas 151 and 152. delete. Executing the processing of S20 to S28 described above for the investigation target brush corresponds to a land area determination step, and the CPU 11 that executes the process corresponds to a land area determination unit.

In S31 executed after S30, the CPU 11 checks whether or not the lot number still remains in each of the save areas 151 and 152. And CPU11 returns a process to S20, when a lot number remains. On the other hand, when the lot number disappears from the save areas 151 and 152 as a result of repeating the loop processing of S20 to S31, the CPU 11 includes a map including a brush corresponding to the judgment target lot number as shown in FIG. (Map including a display of a stroke line and lot number) is drawn on the RAM 15 based on the map graphic attribute table 120, the map graphic connection table 121, and the map graphic coordinate value table 113. In addition, when “determination result = ◯” is registered in the registry area determination result table 118 for each brush on the map, the CPU 11 describes the land area read from the registration information table 119, and “determination” When “result = ×” is registered, the determination result and the value of the “assumed error” field (numeric value of error or “unknown” character) are described. After the above, the CPU 11 displays the completed map image on the RAM 15 on the display (the display 22 when there is an input from the terminal 2 and the display 13 when there is an input from the input device 14). indicate. After the above, the CPU 11 ends the process according to the land area check program.
<Operation>
Next, an operation example of the electronic information processing organization according to this embodiment having the above-described configuration will be described.

Now, it is assumed that there is a partitioned area as shown in FIG. 15, and the lot number and actual area of the land (brush) in the area are as shown in FIG. Note that FIG. 15 is also consistent with the display range of the registry map attached to the area (map drawing No. = A01). However, on the registry (registration information table 119), it is assumed that the land area of each land (brush) in the area is as shown in FIG. That is, accurate lots are registered for lots A, B, F, and E, but lots less than actual are registered for lots C, D, and H, and lots more than actual are registered for lot G. Suppose that In addition, as shown in FIG. 17, there is no geodetic survey map for lot numbers C, G, and H, there is an accurate geodetic survey map for lot numbers A, B, F, and E. It is assumed that there is only a geodetic survey map where the ground area is smaller than the actual area for some reason. As shown in FIG. 18, a residential map exists in the area.

In such a situation, it is assumed that any brush in the area is set as a survey target brush and the land area check program is started. Then, for lot number A and lot number B, there is a geodetic survey map (S03: YES), and the creation date of the geodetic survey map registered in the registry area determination result table 118 is later than 1975. Since there is (S04: YES), it is determined that the land area on the registry (registration information table 119) is reliable (S08). As a result, the output result on the display (13, 22) shown in FIG. 19, lot number A, for of B, acreage on registry (registration information table 119) (80 m ^2, 90m ²⁾ is displayed as it is .

On the other hand, since there is no geodetic survey map for lot number C, the CPU 11 cannot take a method for confirming the accuracy of the geography on the registry (registration information table 119) by comparison with the geodetic survey map (S03). : NO). In this case, the lot number C constitutes a brush group together with the lot numbers A and B. However, since the brush for which no land area survey map exists is only the lot number C in the brush group (S22: NO), the CPU 11 The total area of 245m ² on the registry (registration information table 119) for the brush group and the area of the same block as the brush group calculated from the house map (255m ² , that is, the actual land contained in the block) The total area). If the difference (−10 m ² ) exceeds the reference value (S23: NO), the CPU 11 determines that the land area on the register of the lot number C (registration information table 119) is not reliable (S27). ), The difference between the ^two (−10 m ² ) is determined as the “assumed error” (S28). As a result, in the output result on the display (13, 22) shown in FIG. 19, for the lot number C, the fact that the land area on the registry (registration information table 119) is unreliable (×) and its assumed error (−10 m) ² ) is displayed.

In addition, for lot number E, there is a geodetic survey map, and whether the creation date of the geodetic survey map registered in the register area determination result table 118 is later than 1975 (S04: YES), Even if this is not the case, since the land area matches that in the registry (registration information table 119) (S07: YES), the land area on the registry (registration information table 119) can be trusted anyway. Is determined (S08). As a result, in the output result on the display (13, 22) shown in FIG. 19, for the lot number E, the land area (90 m ² ) on the registry (registration information table 119) is displayed as it is.

On the other hand, for lot number D, although there is a geodetic survey map, since the date of creation is before 1975 (S04: NO), the land area is not accurate (S07: NO). Therefore, the CPU 11 checks the determination result registered in the scale area determination result table 118 for the area survey map created at the same time by the same contractor as the area survey map, and the ratio of “O” is equal to or higher than the reference ratio. It is checked whether or not there is (S16). Here, if the said ratio is less than a reference | standard ratio, CPU11 will compare with a house map similarly to having mentioned above. That is, the lot number E constitutes a brush group together with the lot number D, but the only brush whose ground area survey map is not accurate is the lot number E in the brush group (S22: NO), so the CPU 11 registers the brush group. The total area of the land on the book (registration information table 119) is 180 m ² and the area of the same block as the brush group calculated from the house map (210 m ² , that is, the total area of the land included in the block) Compare If the difference (−30 m ² ) exceeds the reference value (S
23: NO), the CPU 11 determines that the land area on the register of the lot number C (registration information table 119) is unreliable (S27), and determines the difference (−30 m ² ) as the “assumed error” ( S28). As a result, in the output result on the display (13, 22) shown in FIG. 19, with respect to the lot number D, the fact that the land area on the registry (registration information table 119) is unreliable (×) and its assumed error (−30 m) ² ) is displayed.

For lot number F, there is a geodetic survey map, and whether the date of creation of the geodetic survey map registered in the register area determination result table 118 is later than 1975 (S04: YES) Even if this is not the case, since the land area matches that in the registry (registration information table 119) (S07: YES), the land area on the registry (registration information table 119) can be trusted anyway. Is determined (S08). As a result, in the output result on the display (13, 22) shown in FIG. 19, for the lot number F, the land area (75 m ² ) on the registry (registration information table 119) is displayed as it is.

On the other hand, for lot numbers G and H, there is no geodetic survey map, so the CPU 11 cannot take a method of confirming the accuracy of the top land area by comparing with the geodetic survey map (registration information table 119) ( S03: NO). In addition, lot numbers G and H constitute a brush group together with lot number F, but since there is no land surveying map for two lot numbers in the same brush group (S22: YES), the area calculated from the house map and Even by the method of comparison, it is not possible to calculate each assumed error. For the brush group, although the total area (255 m ² ) on the register (registration information table 119) matches the actual area (255 m ² ) calculated from the house map, the area of each brush is actually This is because the area does not match. Therefore, the CPU 11 determines that the land area on the registry (registration information table 119) is unreliable for these lot numbers G and H (S25), and the “assumed error” is also unknown (S26). As a result, in the output results on the display (13, 22) shown in FIG. 19, for the lot numbers G and H, the fact that the land area on the registry (registration information table 119) is unreliable (×) and its assumed error are also shown. The fact that it is unknown is displayed.

  According to the electronic information processing organization according to the present embodiment described above, the viewer and the registrar can easily check the register book (registration information table 119) based on the output result on the display (13, 22) for the investigation target brush. ) You can get an indication of whether the top area is accurate. Therefore, for example, a person who intends to become a land transaction counterparty or a security interest (mortgage, etc.) is displayed (×) that the land area on the registry (registration information table 119) is unreliable for the surveyed writing brush. In such a case, it is possible to prevent troubles caused by errors in the land area by conducting an on-site survey independently to obtain an accurate land area.

  In the present embodiment, the processing from S15 to S19 can be omitted if more strict determination is required.

  Similarly, the process of S04 can be omitted if a more strict determination is required.

  In this example, private roads were excluded from the group of brushes. However, private roads are subject to property changes as long as they are privately owned, and therefore are subject to registration on a brush basis. It may be the subject of the survey. In this case, the brush group includes a private road brush and is surrounded by a public road.

  Moreover, in the present Example, although the determination result whether the land area on the registry was reliable was displayed about all the brushes contained in the same registry-provided map as a survey object brush, processing load is reduced. For this purpose, only the determination result regarding the area of the brush to be investigated may be displayed, and the process may be executed only within a necessary range. For example, if there is a geodetic survey map created after 1975 for the survey target brush, the fact may be displayed at that point, and the process may be aborted.
