Japanese Patent Application Laid-Open No. 2004-77751

  And, it is preferable that the latest information is reflected on the house map as much as possible, and it is important to re-investigate the map information at an appropriate timing. In the case of a re-investigation of a house map, there is little need to acquire detailed information on map components using the map information investigation support device described in Patent Document 1 described above, and information on parts different from the previous investigation is obtained. It only has to be done. For this reason, in the re-investigation of the house map, the printed map of the previous survey (the most recent map reflecting the previous survey) is used as a manuscript and sent to the production department by facsimile. The production department performs a process of updating the original map according to the entry items of the manuscript.

  However, in the production department, it takes time to input the update information in accordance with the entry items of the manuscript. Originally, there is a method of displaying the map on a so-called tablet type information terminal (tablet PC) or the like and inputting the survey result (update information) on the map instead of describing the update information on a paper map. preferable. This is because the information input to the tablet information terminal can be used as it is for updating the original map, and it is not necessary to input update information in the production department. However, in the case of a tablet-type information terminal, it may be difficult to use for a map survey in terms of size, weight, battery duration, and the like.

  In view of the above, the present invention digitizes and grasps map survey contents as much as possible without human intervention while using a conventional method of hand-filling survey results in a printed map at the time of the previous survey. The purpose is to be able to.

In order to solve the above-mentioned problem, the map survey update registration method of the invention according to claim 1 comprises:
A grid is attached to the entire description of the map in the survey area, and a map survey form with identification information in each row and column of the grid is distributed to the investigators.
When the investigator finds a place on the map where the information should be updated, the investigator identifies each row and each column of the lattice, predetermined identification information indicating new, change, and deletion, and update contents; And fill in the update information on the map survey form,
After the survey is completed, the update information entered on the map survey form is read using an OCR (Optical Character Reader) and stored in a predetermined recording medium.

  According to the map survey update registration method of the invention described in claim 1, a map of a survey target area is described, and a grid is attached to the entire description portion, and identification information is provided in each row and each column of the grid. A map survey form marked with is distributed to the surveyors. When the investigator finds a place on the map where the information should be updated as a result of the survey, the identification information for each row and each column of the lattice, the identification information that means new, changed, or deleted predetermined, and the update contents The update information is entered in the map survey form.

  Then, after the survey is completed, the update information handwritten on the map survey sheet is read using the OCR and stored in a predetermined recording medium. The update information includes position coordinate information on the map survey form. That is, handwritten update information can be acquired as digitized update information with position coordinates.

  As described above, since the map update information is read using the OCR, it is not necessary for the user to input based on the description on the map survey form. Even if a reading error occurs in OCR, correction is possible. As a result, it is possible to grasp and arrange the survey contents as much as possible without bothering human hands. Then, changes can be reflected in the original map using the prepared survey contents.

  According to the present invention, the map survey contents can be digitized and grasped as much as possible without bothering humans as much as possible, while using the conventional method of hand-filling the survey results on the printed map at the time of the previous survey. .

[Overview of map survey update registration method]
FIG. 1 is a diagram for explaining an outline of a map survey update registration method to which an embodiment of the method of the present invention is applied. FIG. 2 is a diagram for explaining an example of the map survey paper 1 used in the map survey update registration method of this embodiment, and FIG. 3 is another survey paper that forms part of the map survey paper 1. It is a figure for demonstrating the example of (the separate page of the map investigation paper 1).

  In FIG. 1, a map survey form 1 is a printed map of the survey area at the time of the previous survey, and the surveyor enters the map survey results in the field by hand. However, the map survey sheet 1 used in this embodiment is not simply a printed map. As shown in FIG. 2, the map survey sheet 1 has a grid attached to the entire description portion of the map, and each row of the grid has numeric identification information (1, 2, 3,...). Each column is provided with alphabetic identification information (A, B, C,...). Thereby, the described map is subdivided and each subdivided area (block) of the map can be specified.

  As shown in FIG. 2, the “row” of the grid is divided in the vertical direction of the map survey paper 1, and the “column” of the grid is divided in the horizontal direction of the map survey paper 1. Meaning each part. In addition, as shown in FIG. 2, in the map survey form, in the case of this example, the latitude / longitude information of the diagonal, the scale, the address code, the reference number, the survey date entry column, Necessary information such as the surveyor code column is described. In addition, at the four corners of the map survey paper 1, cross-shaped four-corner markers indicating the reading range of the map survey paper are attached.

  Further, in the case of the example shown in FIG. 2, for the sake of simplicity of explanation, a case where a 10 × 10 grid is provided is shown, but the present invention is not limited to this. A grid having an appropriate number of rows and columns can be provided depending on the size of the paper, the width of the rows, and the columns. Of course, the number of rows and columns need not be the same. Further, when 27 or more columns are provided, for example, identification information that can be distinguished from identification information that has already been used, such as “AA, BB, CC,...” Or “AX, BX, CX,. What should I do?

  Further, information that cannot be written on the building frame of the map printed on the map survey form 1, for example, tenant information on each floor of the rental building is described on a separate page of the map survey form 1. In this embodiment, when a map survey sheet for a region with a separate page is printed, a separate survey sheet for describing another page is printed at the same time. This separate survey form is integrated with the map survey form 1 shown in FIG. Then, when the building indicated by the building name “XX building” in the map survey form 1 shown in FIG. 2 is, for example, a 5-story rental building, another survey form as shown in FIG. 3 is created. . In the separate survey form shown in FIG. 3, information on tenants occupying each floor of the building indicated by the building name “XX building” in the map survey form 1 shown in FIG. 2 is described.

  The information on this separate survey form also corresponds to the latest survey information. Further, as shown in FIG. 3, the margin on the upper end side of the separate survey sheet also includes the corresponding map survey sheet reference number, another page number. The survey date column and surveyor code column are described. By this description, the map is associated (linked) with the map survey form on which the map is described. In addition, four corner markers indicating the reading range are also described on the separate survey sheet.

  Then, a map survey form (including another survey form) 1 formed as described with reference to FIGS. 2 and 3 is created and distributed to the surveyors. When the researcher finds a place where the information described in the map survey form 1 is to be updated in the field survey, the researcher writes the update information in the map survey form 1 by hand. At this time, the handwritten information is described in accordance with a very simple description method determined in advance so that the information can be accurately read by an OCR (Optical Character Reader).

  For example, specific update information is described with predetermined identification information indicating whether the content of the update is new, changed, or deleted and, for example, “” (quotes) indicating the update information. As an example, new = black star mark, change = black square mark, and delete = black circle mark are used as shown in the upper right corner of the map survey sheet 1 of FIG. Here, “new” is used when there is a building or the like that is not on the map at the previous survey. “Change” is used when, for example, the building has not changed on the map of the previous survey, but the occupant has changed. “Delete” is used when a building or the like existing on the map at the previous survey was demolished and cleared.

  More specifically, as shown in FIG. 2, the building nameplate in the block (position) indicated by the column “C” and the row “5” was previously “Yamamoto” In this survey, it was assumed that it was “Suzuki”. In this case, first, “black square mark” indicating “change” is written (filled) in a block indicated by “C” in the column and “5” in the row using a stamp or the like, and then the “black” Following the “square mark”, the block number “C5” of the block is described, and the character “Suzuki”, which is the description content of the new nameplate, is described. In addition, the existing description of “Yamamoto” in the corresponding part of the map survey form 1 is deleted with a double line. This clearly indicates that the description of the block whose column is “C” and whose row is “5” (the block whose block number is “C5”) has been changed from “Yamamoto” to “Suzuki”. it can.

  In addition, as shown in Fig. 2, the building in the block with the column "E" and the row "5" was formerly a liquor store called "Yamada liquor store". Suppose that it has changed to “Convenience store Yamada”, which is a store of a convenience store chain. In this case, since it becomes difficult to see the map if it is described on the map, the update information is described in the blank portion of the map survey sheet 1. That is, in FIG. 2, a “black square mark” indicating “change” is first described (filled) using a stamp or the like in the lower margin of the map survey sheet 1 and then the “black square mark”. Following this, the block number “E5” indicating the changed part is described. Following this, the name “Yamada liquor” before the change and the name “Convenience store Yamada” after the change are described. This clearly indicates that the description of the block whose column is “E” and whose row is “5” (the block whose block number is “E5”) has been changed from “Yamada liquor store” to “Convenience store Yamada”. be able to.

  Further, as shown in FIG. 2, it is assumed that a building built in a block indicated by “C” in the column and “8” in the row is demolished and cleared. In this case, “black circle” indicating “deletion” is described (filled in) in a block indicated by “C” in the column and “8” in the row by using a stamp or the like, and subsequently, the deleted portion The block number with “C8” is indicated. As a result, it is possible to clearly indicate that the building built in the block having the column “C” and the row “8” (block number C8) has been demolished and cleared.

  Further, as shown in FIG. 2, it is assumed that a new building is built in a block whose column is “I” and whose row is “9”, and a nameplate “Tanaka” is placed. In this case, first, “black star” indicating “new” is written (filled) in a block whose column is “I” and row is “9” using a stamp or the like, and then the “black star” is displayed. Following the “mark”, the block number “C8” indicating the update location is described. Furthermore, the characters “Tanaka”, which is the description content of the nameplate, are described. As a result, a new building was built in the block with column “I” and row “9” (block number “I9”), and the nameplate “Tanaka” was placed there. It can be clearly shown. In addition, in the case of addition, the building frame corresponding to the actual measurement location is also described.

  In the map shown in FIG. 2, tenants on the 5th floor of “XX Building”, which is built around a block whose column is “F” and whose row is “8”, are changed from “XX Trading” to “△△”. Suppose it has changed to “Industry”. In such a case, since the object is a rental building, it is normal that the update information of each floor cannot be described on the map survey form shown in FIG. For this reason, the update information about the tenant of the rental building is described in a separate survey form that forms a part of the map survey form 1 described with reference to FIG. In this case, the “building name” and the “block number” are linked (linked) to the description of the map survey form shown in FIG.

  That is, as shown in the lower end side of FIG. 3, first, “black square mark” indicating “change” is described (filled in) in the update classification field of the blank part of the separate survey form using a stamp or the like. In order to identify the building to be updated, “XX building” is described in the building name column, and “F8” is described in the block number column. Then, ““ 5th floor ”,“ XX trading ”,“ △△ industry ”” is written in the content column. As a result, the description on the fifth floor of “XX Building” of the block having the column “F” and the row “8” (block number “F8”) is changed from “XX Trading” to “△ It can be clearly shown that it has been changed to “industry”. In the separate survey form of the map survey form 1 shown in FIG. 3, a field for entering update information is separately provided. As shown in FIG. By providing one character frame as a frame, it is useful for entering characters that are easily recognized by OCR.

  In this way, a grid is provided in the map description portion, and the surveyor conducts a field survey using the map survey sheet 1 (including another survey sheet) in which each block of the grid is assigned a block number. And, as described above, the update information on the map survey form 1 is written in accordance with a predetermined description method using identification information indicating new, changed, and deleted and “” (quotes). Describe. The identification information indicating new, changed, or deleted is not limited to the black star mark, black square mark, and black circle mark described above. Other symbols may be used, and the update type may be indicated by color, such as new = red, change = blue, and deletion = yellow. This is because colors can also be recognized using OCR.

When the on-site map survey is completed, the map survey form 1 is taken home, and as shown in FIG. 1, the scanner 2 and the personal computer 3 (a device comprising a personal computer main body 31, a display 32 , a keyboard 33, and a mouse 34). Process by. In this embodiment, the scanner 2 and the personal computer 3 constitute a map survey information processing apparatus that processes map survey information.

  Here, the map survey information processing apparatus will be described. After the on-site map survey using the map survey sheet 1 is completed, the information written on the map survey sheet 1 is read through the scanner 2 and stored in the recording device of the personal computer main body 31. In this case, as will be described later, the information stored in the recording device includes the digitized data of the map survey sheet 1 (including another survey sheet) and the necessary information or update read on the map survey sheet 1 and read by the OCR. Information (information such as symbols and characters). Here, as described with reference to FIG. 2, the necessary information is written in the latitude, longitude, scale, address code, reference number, survey date written in the survey date column, and surveyor code column. This is the investigator code. For this reason, the personal computer main body 31 is equipped with scanner software that captures the description content of the document as electronic data (image data) through the scanner 2 and OCR software that reads characters and symbols described in the document.

The personal computer main body 31 includes a control unit 311, a recording device 312, an input device interface 313, an external I / F 314, a display processing unit 315, and a display I / F 316, as shown in the lower side of FIG. It is a thing. The control unit 311 controls each unit of the personal computer main body 31, and is configured by connecting a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) through a CPU bus (not shown). Computer device.

The recording device 312 is a hard disk drive (HDD) in this embodiment, and includes a hard disk as a recording medium, and writing / recording / reading / reading / writing data to / from the hard disk with various application programs and data obtained by various processes. Perform deletion. In this embodiment, the recording device 312 records various application software such as the above-described scan software and OCR software. The recording device 312 records the digitized data of the map survey sheet 1 read using the scan software and the update information read using the OCR software. In this embodiment, map original data and the like are also recorded in the recording device 312.

The input device I / F 313 is a part that exchanges information with various input devices such as a keyboard 33 and a mouse (pointing device) 34. In this example, the external I / F 314 is a part that exchanges information with the scanner 2. The display I / F 316 is a part that exchanges information with the display 32. In these input device I / F 313, external I / F 314, and display I / F 316, the information to be output is converted into a format according to the partner, or the information received from the partner is converted into a format that can be processed by the own device. Also perform processing. The display processing unit 315 performs various types of display information according to the control of the control unit 311 and supplies the display information to the display 32 through the display I / F 316.

  Then, the user first sets the map survey paper 1 on the scanner 2, performs a predetermined operation input through the keyboard 33, and activates scan software in the control unit 311 of the personal computer main body 31. Then, the scanner 2 is controlled through the personal computer main body 31, and processing for reading the description content of the map survey paper 1 by the scanner 2 is started. In this case, as identification information to be added to the digitized data obtained by scanning, for example, information such as a serial number, a survey date, a surveyor code attached to the map survey paper 1 is input through the keyboard 33.

  The scanner 2 reads the contents of the map survey sheet 1 set according to the control of the personal computer main body 31 and sends the read information to the personal computer main body 31. The personal computer main body 31 receives information from the scanner 2 through the external I / F 314, adds predetermined information such as a serial number input thereto, and records it in a predetermined recording area of the recording device 312. In this way, the digitized data of the map survey sheet 1 (a document that has just been scanned) is recorded in a predetermined area of the recording device 312.

  FIG. 4 is a diagram for explaining an example of digitized data of the map survey sheet 1 read by the scanner 2 and recorded in the recording device 312 of the personal computer main body 31. As shown in FIG. 4, the digitized data includes a header portion made up of the input reference number, survey date, investigator code, etc., and a storage portion for digitized data of the map survey form 1 read by the scanner 2. It consists of By reading out and processing the digitized data of the map survey paper 1 as described above, the description content of the map survey paper 1 can be displayed on the display 32.

  Thereafter, the user activates the OCR software in the control unit 311 of the personal computer main body 31 by performing a predetermined operation through the keyboard 33. The OCR software analyzes the image data read through the scanner 2, reads the written characters and symbols, and acquires them as text data, for example. In this case, the user uses the keyboard 33 to process the digitized data of the map survey paper 1 through the keyboard 33, and reads the necessary information and the handwritten characters and symbols present in the digitized data of the map survey paper 1 using the OCR software. Start.

  In this embodiment, as described with reference to FIGS. 2 and 3, the diagonal latitude, longitude, scale, address code, reference number, and the like described in the upper margin of the map survey sheet 1 or another survey sheet, Read necessary information such as the description in the survey date column and the description in the surveyor code column. Further, as described above, the handwritten update contents enclosed by “black star”, “black square”, “black circle” and “” (quotes) indicating the update type are read. That is, since the information with “black star”, “black square”, and “black circle” is update information, it recognizes the identification information, grasps its contents, and follows the identification information. A process of reading handwritten characters enclosed in (brackets) as update information is performed. The read information is recorded in the predetermined storage area of the recording device 312 by the control unit 311 as update information.

  FIG. 5 is a diagram for explaining an example of the update information that is read from the digitized data of the map survey sheet 1 and recorded in the recording device 312 by the OCR software. The update data includes a header portion including necessary information that has been read, and a storage portion for storing detailed information of the read handwritten portion. The example shown in FIG. 5 is information obtained by character recognition of the digitized data of the map survey form 1 (including another survey form) described with reference to FIGS. 2 and 3 using OCR software. Therefore, as described with reference to FIGS. 2 and 3, the change information for the blocks having the block numbers “C5”, “E5”, and “F8” and the deletion information for the blocks having the block number “C8”. The new (additional) information for the block having the block number “I9” is described. That is, the update information written in handwriting on the map survey sheet 1 can be acquired as update information with digitized position coordinates (block number).

  Such update information read by the OCR software is displayed on the display 32 and used for updating the original map. In the case of this example, when there are two names enclosed in “” (quotes), the previous description is old information and the subsequent description is new information. In addition, when there is one name enclosed in "" (quotes), the information is new information.

The update information read by the OCR software may include misread (erroneously recognized) characters. Therefore, the user performs a predetermined operation through the keyboard 33 to display the digitized data of the map survey sheet 1 shown in FIG. 4 and the read update information shown in FIG. Then, update information correction processing is executed. In this case, the control unit 311 reads an application that performs processing according to an instruction from the user from the recording device 312 and executes the application.

  The application reads the digitized data of the map survey form shown in FIG. 4 and the update information shown in FIG. 5 linked by, for example, a reference number, and displays them on the display screen of the display 32 so that the display areas are different. To display. Then, the application receives a correction input for the displayed update information through the keyboard 33 and the mouse 34, and performs a process of reflecting the correction input in the update information recorded in the recording device 312. Thereby, the update information read by the OCR software can be made more accurate.

  In addition, the image according to the digitized data of the map survey form 1 displayed on the display 32 and the image according to the read update information are each scrolled, and a part that cannot be displayed is also displayed and confirmed. The read update information can be corrected.

  And the update process of the original map can be performed using the update information arranged in this way. In this case, when the user performs a predetermined operation through the keyboard 33, the control unit 311 of the personal computer main body 31 reads the map original update software from the recording device 312 and executes it. The application reads the map information corresponding to the original map stored in the recording device 312 and the update information shown in FIG. 5 and displays them on the display screen of the display 32 with different display areas. In this case, the map corresponding to the map original and the update information shown in FIG. 5 are linked by, for example, diagonal latitude and longitude information held as header information by the update information.

  Then, compare the displayed map information with the update information, identify the part of the map information to be updated, delete the description of the specified part, and update the new information (information obtained in this survey). ) To update the original map information. In this case, the original map is displayed with the same grid as the map survey paper 1 and identification information of each row and column of the grid, and the image of the map survey paper 1 based on the digitized data is also displayed. The update position can be specified accurately by displaying the information.

  In this way, it is not necessary for the user to manually input the update information while viewing the handwritten description on the map survey sheet 1 as in the prior art, and the update information read by the OCR can be used as it is. Accordingly, it is possible to obtain remarkable effects such as reducing the user's trouble and reducing input errors.

[Summary of map survey update registration method]
Next, the map survey update registration method described with reference to FIGS. 1 to 5 will be summarized with reference to the flowchart of FIG. FIG. 6 is a flowchart for explaining the overall flow of the map survey update registration method of this embodiment.

  In the map survey update registration method of this embodiment, as shown in FIG. 6, first, a map in which the necessary information described with reference to FIGS. 2 and 3, the identification information of the grid and each row and each column of the grid is printed. A survey form (including another survey form) 1 is created and distributed to the surveyor (step S101). The processing in step S101 is advance preparation for a map survey. Then, using the distributed map survey form 1, the investigator visits the survey site, conducts a field survey, and as described with reference to FIGS. 2 and 3, the update information is handwritten on the map survey form 1. (Step S102). That is, the process of step S102 is performed by using the identification information of each row and each column of the lattice described in the map survey form 1, the identification information indicating new, changed, and deleted, and “” (quotation marks). This is a process of writing update information on the map survey sheet 1 by hand so that the location and update contents can be understood. The process in step S102 is a map survey process performed by a researcher.

  Then, after the completion of the map survey, the researcher takes home the map survey form 1 and performs an electronic process using the map survey information processing apparatuses 2 and 3 after step S103. The process after step S103 may be performed by an investigator or may be performed by another person. In this case, first, the user executes scan software in the personal computer 3. Then, the scanner 2 is controlled through the personal computer 3, the map survey sheet 1 used for the map survey is scanned through the scanner 2, and the digitized data of the map survey sheet 1 is stored in the recording device 312 (step S103). Next, the user executes OCR software in the personal computer 3. Then, the OCR software executed on the personal computer 3 reads the necessary information and the information written in handwriting from the digitized data of the map survey sheet 1 that has been already taken in, and stores this in the recording device 312 as update information. (Step S104).

  Then, the user corrects the update information read and stored by OCR using the personal computer 3 (step S105). In step S105, the control unit 311 of the personal computer main body 31 controls the display processing unit 315 in accordance with an instruction from the user, the image corresponding to the digitized data of the map survey sheet 1 used for printing, Update information on the region corresponding to the digitized data is displayed on the display 32. Then, both the displayed image and the map survey sheet 1 on which the update information is written are compared and verified, and if there is an error in the update information read by the OCR software, correction is performed. This ensures the accuracy of the update information.

  In this way, the update information obtained by conducting the map survey can be grasped by digitizing it, and its accuracy can be sufficiently ensured. The update information with guaranteed accuracy can be used to correct the original map.

[Effect of the embodiment]
As described above, the update information written in handwriting on the map survey sheet 1 can be read by OCR and corrected to ensure accuracy, and then used for updating the original map. That is, in the past, the update of the original map has been input for direct digitization based on the update description written on the map survey form, whereas in the case of the above-described embodiment, Can digitize the update information and use it to update the original map. Therefore, it is possible to reduce the load of the update process for the original map and improve the accuracy and reliability of the update process.

[Modification]
Note that the map portion of the map survey sheet 1 is magnetic ink in order to reliably discriminate the information or hand stamps written on the map survey sheet 1 from the original map (the map portion described on the map survey sheet 1). You may print by. Further, in the map survey paper 1, the grid printed on the map survey paper 1 may be printed with magnetic ink in order to accurately distinguish the grid from the roads and building lines on the map. FIG. 7 is a diagram for explaining a modification of the map survey sheet 1 created using magnetic ink.

  FIG. 7A shows an example of a map survey sheet 1 in which a map portion indicated by a dotted line is printed using magnetic ink. Magnetic ink is special ink having magnetism and can be read by a magnetic ink reader. Normally, magnetic ink is printed as a special color other than C (cyan), M (magenta), Y (yellow), and K (black), and is invisible to the user. However, although it is visible, if it is printed and used in combination with a color that is set not to be read by the scanner, it can be prevented from being confused with the description on the survey form when recognizing handwritten characters using OCR software, It is possible to reliably distinguish between handwritten information and hand stamps and map portions.

  For example, it is assumed that a map survey sheet in which the map portion indicated by the dotted line in FIG. 7A is printed with magnetic ink is used, and that the block portion indicated by the block number “C5” has changed. In this case, even if update information such as “black square mark”, “C5”, “Suzuki” is written in the block indicated by the block number “C5”, the map itself is printed with magnetic ink, It is possible to skip reading during OCR recognition of update information. In addition, by reading the map itself using a magnetic ink reader, it is possible to obtain a correction value for displacement due to printing and printing and distortion due to temperature / humidity by comparison with an image corresponding to the digitized data of the map survey paper. .

  Instead of magnetic ink, the map portion is printed with a color other than C (cyan), M (magenta), Y (yellow), K (black), and other colors that are set not to be read by the scanner. Also good. Even in this case, the same effect as when the above-described map portion is printed with magnetic ink can be obtained.

  FIG. 7B shows an example of the map survey sheet 1 in which the grid itself is printed using magnetic ink instead of printing the map itself with magnetic ink. In this case, as shown in FIG. 7B, the grid and the roads and building lines on the map can be clearly distinguished. Therefore, the update information can be appropriately described for the location (block) on the map where the change is found. In addition, as shown in FIG. 7B, a printing company is requested, and as shown in FIG. 7B, a grid and a block number of each block (in FIG. 7B, for example, A1, A2,..., B1, B2,...) A large amount of paper printed with magnetic ink may be prepared, and the map survey paper may be printed using the paper.

  Further, in the process of the flowchart shown in FIG. 6, the process of step S103 and step S104 is performed in the map research department, the update information read by the OCR is sent to the map production department, and the process of step S105 is as follows. You may do it in the map production department. Of course, the process from step S103 to step S105 may be performed by the research department, the calibrated update information may be sent to the map production department, and the map update process may be performed by the production department. That is, the processes in steps S103 to S105 shown in FIG. 6 can be performed by different users in different places at different locations.

  The update information read by the OCR can be sent to the production department using upload to a cloud server, e-mail, network transfer using FTP (File Transfer Protocol), or the like. Of course, it is also possible to use a method such as storing update information read by OCR in a recording medium and mailing it. That is, the data sending method is not limited to the above-described one, and various methods can be used.

  In addition, as described above, if the map survey form is unified between the survey form with the map linked with the building name and block number and the separate survey form on a separate page, it will be updated for each investigator. Prevents the description of information from becoming different, improving the efficiency of investigation and processing.

[Others]
As is clear from the above-described embodiment, the method described with reference to FIGS. 1 to 7 corresponds to the map survey information update registration method of the present invention. Further, the processing from step S103 to step S105 shown in FIG. 6 corresponds to a map survey information processing program executed in the control unit 311 of the personal computer main body 31 constituting the map survey information processing apparatus.
