Description

  The present invention relates to a real estate information updating system for acquiring and updating real estate information for taxation purposes.

Municipalities regularly check land and houses to update real estate information in order to properly tax on real estate. When updating real estate information, an investigator visits the site to check roads and buildings against the map, and checks whether there is any change in the real estate information surveyed last time. Specifically, for example, the investigator visually confirms that the land texture has not changed compared to the previous photo (for example, a change in which a place that was a field has become a parking lot), or a new construction Check for changes in houses, such as whether objects have been stood, built, or dismantled, or for roads (routes), such as whether the road is widened or whether there is a gutter lid. The investigator takes a picture of the current situation as needed, and additionally fills in a notebook or the like as text information to record the change in the current situation or if there is no change in the current situation. The investigator is, for example, a public employee in charge of a municipality or a person who performs real estate appraisal work under commission from the municipality.
Patent Document 1 is given as an example of a system for updating such real estate information. Patent Document 1 is a system in which a route price is calculated by a computer based on updated real estate information and associated with map information.

JP 2002-183378 A

However, in the conventional system for updating real estate information including Patent Document 1, in any case, the investigator visits the site to acquire the real estate information by some recording means (for example, notebook, notebook, camera, etc.) If it is not brought back to the company or office and entered into the computer, it cannot be updated as electronic data and made into a database. Also, whether or not all the real estate information of the real estate to be checked has been checked must be written on the map while collating with the map. Therefore, conventionally, it has been very troublesome to update real estate information and create a database.
The present invention has been made to solve the above problems, and the purpose of the invention is to enable real estate information to be obtained on the spot by an investigator and to create a database as electronic data. It is to provide an information update system.

In order to achieve the above object, in the first means, a portable terminal device having a display unit for displaying a map including its own position based on position information obtained by satellite positioning, and Control means for displaying a real estate information at a predetermined position on the displayed map and displaying real estate information of the real estate at the position on the display section, and displaying the real estate displayed on the display section The gist includes an input means for changing information and a storage means for storing the real estate information changed by the input means.
In such a configuration, the investigator can carry the portable terminal device and display a map including his / her position on the display unit by satellite positioning. Then, a predetermined position (real estate position) on the map is designated. Then, real estate information corresponding to the position is displayed on the display unit. The investigator confirms the actual status of the specified property on the map. Then, check whether there is any change in the real estate information of the real estate, and if there is a change, for example, check a predetermined check item displayed on the display unit, or measure and obtain a numerical value and display it on the display unit The real estate information is updated directly on site, such as by inputting into the displayed input area, taking a picture, obtaining a new image, typing necessary items, and so on. The acquisition method of real estate information is basically the same as a well-known investigation method. And the acquired real estate information is preserve | saved in a memory | storage means as electronic data on the spot.
As a result, it is no longer necessary to re-record the information once recorded in a recording means such as a notebook, etc., for renewal of the real estate information as in the prior art, and it becomes easy to create a new real estate information database. . In addition, real estate information corresponding to the designated real estate position is displayed on the display screen, and the real estate information can be accessed and changed, so the real estate information corresponding to the designated real estate position may be mistaken. Absent.

Here, “position information obtained by satellite positioning” is position information in which latitude and longitude acquired by a GPS (Global Positioning System) function are specified. A map linked to this position information is displayed on the display unit so that the scale can be changed.
As the “portable terminal device”, for example, a laptop to a notebook computer (including a tablet PC, a netbook, and a smart book), a PDA (Personal Digital Assistant), a tablet, a smartphone, and the like are preferable.
“Real estate information” refers to information on real estate (land or building), such as route type (paved / unpaved), route width, route gutter status, etc. Car park etc.) Standard housing land condition, house condition, etc. The line price is also real estate information in a broad sense. “Changing real estate information” means adding, modifying, or deleting real estate information based on the current situation. In addition, it is said that it is “updated” by checking the real estate information after changing it in this way or checking the current situation without changing it and saving it as electronic data so that it can be taken out.
In the case of “designating a predetermined position on the map”, if the display unit has a touch panel function, the investigator contacts the position where the survey of the displayed map is necessary. You may make it designate with designation | designated means like the cursor displayed on a map.
The “display unit” is a display on which a moving image or a still image is displayed. For example, the display unit is an organic EL display, a liquid crystal display, a CRT display, or the like.
The “input means” may be, for example, a GUI input screen that can be input by touching a display surface with a keyboard or mouse.
The “storage means” may be arranged in the portable terminal device, or may be arranged in a server on the network connected by the Internet or a LAN (Local Area Network), for example.

The gist of the second means is that the map and the real estate information are simultaneously displayed on the display unit.
If comprised in this way, since real estate information is displayed in relation to the position of the real estate shown on the map, the investigator can check the real estate information while confirming the real estate position. Further, it can be understood from the contents of the second means that the first means is also claimed when the map and the real estate information are not simultaneously displayed on the display unit. Also, the designated position may be marked in some form so that the designated position can be clearly seen on the map.

In a third means, the portable terminal device includes a contact state detection unit, and the control unit is configured to detect the contact of the display unit on the map based on a detection value when the contact state detection unit detects the contact. The gist is to display real estate information on the display unit.
This is a case where the display unit has a touch panel function. Thus, if the real estate information to be called up by touching on the map of the display section can be displayed on the display section, the real estate that the investigator wants to check can be displayed without fail, and work efficiency is improved.
The gist of the fourth means is that the control means causes the contact position on the map to be marked on the map.
By marking the contact position on the map in this way, it is possible to easily confirm which real estate information is currently checked.

The gist of the fifth means is that the control means controls the map display so that the current position of the portable terminal device is a fixed position on the map.
As a result, when the investigator moves, the map automatically moves along with the movement, so that the position of the investigator is always constant, so that the map can be viewed based on his / her position and the position can be easily grasped. Moreover, it is convenient because it is not necessary to move the map by itself. It is preferable to display the fixed position at the center or near the center of the map because it is easy to see and the surroundings of the position where it is located are displayed evenly in any direction. Further, this position may not be clearly indicated on the map (that is, marked).
The sixth means is characterized in that, in the fifth means, the control means causes the current position of the portable terminal device to be marked on the map.
As a result, the current position on the map of the researcher can be understood at a glance, so that the survey area can be easily grasped. In addition, since the current position can be immediately recognized, for example, the direction and the amount of investigation to be investigated can be generally grasped, which is convenient.

The gist of the seventh means is that the control means causes the specified position on the map to be marked on the map.
As a result, a predetermined position on the map corresponding to the real estate information displayed on the display unit can be confirmed on the map, so that it is readily known which real estate is being checked.

The gist of the eighth means is to input that there is no change in the real estate information displayed on the display unit by the input means.
That is, when there is no need to change the real estate information when checking the real estate, this is input in a confirming manner. Thereby, it is possible to update the data indicating that the real estate information of the real estate has not changed from the previous update.

According to a ninth means, the gist is that the control means collectively displays information indicating that the real estate information of the real estate to be updated is not updated when the real estate information is not updated.
As a result, when the real estate information has not yet been updated, it can be determined based on the information “not updated” rather than on a broad map, so that the real estate to be updated is not forgotten to be updated. “Not updated” information should be displayed in a list. In addition, since such a display is always complicated to display on the display unit, it is preferable to call it by an input means. Not only the information “not updated” but also the information “updated” may be displayed together. Also, “collective display” is not diffuse, but refers to a case where, for example, the display is concentrated on a certain partitioned area.
The tenth means is the ninth means characterized in that, when the real estate information is updated, the control means causes the corresponding real estate on the map to be displayed differently from that before the update.
As a result, it is possible to easily distinguish on the map real estate for which certain real estate information has already been updated from other real estate that has not yet been updated.

The eleventh means is characterized in that the real estate information is information that affects the tax amount of land or building.
This is because the purpose of the present invention is to provide a system for municipalities to accurately tax. However, it is free to enter information that does not affect the tax amount into this system.

The gist of the twelfth means is that the storage means is in a server on a wide net using the Internet.
With such a configuration, since the update data of real estate information input from the portable terminal device is stored in a server on the wide net instead of the portable terminal device, the real estate information of a large number of real estate is converted into data Can be stored without difficulty, and can be easily used from another terminal device.

  According to the present invention, since the real estate information can be updated on-site by the portable terminal device, it is not necessary to input the information once recorded in a recording means such as a notebook into the computer and record it as in the past. It becomes easy to create a database of information.

Embodiments and examples embodying the present invention will be described below with reference to the drawings.
First, an overview of this system will be described. As shown in FIG. 1, this system includes a tablet 11 as a portable terminal device connected to the Internet. The Internet is a communication network in which a plurality of LANs (Local Area Networks) 12 are connected on a large scale through communication lines such as telephone lines. The tablet 11 is a WWW (World Wide Web) client connected to the Internet. The tablet 11 is an information processing apparatus having a normal hardware configuration capable of executing a program in accordance with a user input. This system includes a server 13 connected to the Internet. The server 13 is an information processing apparatus having a hardware configuration capable of loading a program onto a memory and executing it according to an instruction from the outside. The built-in hard disk as storage means in the server 13 has map data, real estate location data on the map, real estate information data for each real estate associated with the location data, and a file that can be used when a request is received via a browser ( Here, httpd (HyperTextTransferProtocolDaemon) gives the selected map data and past real estate information data database) to the browser, CGI (CommonGatewayInterface) script (program) that processes data from httpd, and various calculation programs started by the CGI script Software such as a map display program and an OS (Operation System) is installed.

Next, the main electrical configuration specialized for the present invention of the tablet 11 will be described.
The tablet 11 includes a CPU (Central Processing Unit) 21 as control means. Connected to the CPU 21 are a display 22, a memory 23, a cache memory 24, a GPS receiver 25, a touch panel 26, an interface 27, and the like as a display unit. The CPU 21 is connected to the LAN 12 via the interface 27.
Under the control of the CPU 21, the display 22 displays the contents of various programs on the screen so that, for example, a web page for updating real estate information is called and displayed on the browser. The display 22 also serves as a touch panel 26 as an input means, and when a contact with a predetermined position on the display 22 (touch panel 26) is detected, a screen capable of GUI input is called and a predetermined numerical value or character can be input. Prompt for a check.
A memory 23 composed of an SSD (Solid State Drive) includes a browser program necessary for using the WWW, a touch panel processing program for processing input to the touch panel 26, and GPS information for processing GPS information received by the GPS receiver 25. Various programs such as a GUI input program for prompting a user input by displaying a screen for processing and GUI input superimposed on the map screen or independently displayed on the display unit 17 and an OS are stored. The cache memory 24 made of SSD temporarily stores, for example, data called on the browser or input data. The GPS receiver 25 detects the position of the tablet 11 at the current time based on an instruction from the CPU 21.

Based on the input of URL (Uniform Resource Locators) of a predetermined site, the CPU 21 requests the server 13 to browse a web page for updating real estate information. On the server 13 side, a CGI script is executed in response to this request so that a map of a predetermined area for updating the real estate information and a table for updating the real estate information can be viewed on the tablet 11 on the WEB page. The browser on the display 22 is activated to display the WEB page. The CPU 21 acquires the position information of the tablet 11 based on the detection value of the GPS receiver 25 and causes the display 22 to display a map so that the center of the map is always the position of the tablet 11.
Further, when a predetermined input is made on the WEB page, the CPU 21 transmits the data to the server 13 side to make an update request. Examples of the input include numerical input to a table for updating real estate information and check input for updating. On the server 13 side, a CGI script is executed in response to this request. When real estate information data is input on the tablet 11 side, the real estate information data database is updated on the server 13 side.

Next, a specific example in which the investigator actually updates the real estate information by displaying the WEB page for updating the real estate information on the display 22 using the tablet 11 will be described.
<Example 1: Update of house information>
The investigator (user) inputs the URL of the site of the server 13 by a well-known operation in advance so that the tablet 11 can browse the region to be surveyed, and carries the tablet 11 and visits the region to be surveyed. Then, the browser of the tablet 11 is activated to browse a web page for updating the house information from the display 22. The researcher's access to the tablet 11 is performed by GUI input to the touch panel 26. The house information is necessary as information for taxing the house and is updated every year.
FIG. 3 is an example of the WEB page of the first embodiment displayed on the display 22. Thus, only the map screen 31 is displayed on the initial screen. Although the tablet 11 always exists in the center of the map screen, the position of the tablet 11 is not displayed on the map in the first embodiment. On the map screen 31, a house object 32 is displayed at the actual position of the house. Each house object 32 is created with reference to the outline when the actual house is viewed in plan. The house object 32 is displayed in a different color for each attribute. The house object 32 is divided into four types of attributes: 1) an unexamined house displayed in red, 2) an already surveyed house displayed in green (no change from the previous survey), 3) pink An unknown house to be displayed 4) It is a house trace that once existed and is now displayed in black.
When the investigator touches (contacts) an arbitrary house object 32 on the display 22 (touch panel 26), the real estate information of the house object 32 is displayed in the blank area on the right side of the map screen 31 as shown in FIG. A table 33 serving as an input screen is displayed. Simultaneously with the touch, a balloon 34 appears as a marking indicating the position touched on the house object 32. Then, the color of the touched house object 32 changes to a color different from the color before the touch (blue in the first embodiment).

The table 33 displays a check box object 35 and a save button object 36 for selecting any one of the above 1) to 4). Also, below the check box object 35, an image (photo) 37 of the house (no photo in the first embodiment), a family register information column 38 including a family register information and a memo column are provided. . The family register information column 38 can be scrolled up and down.
The investigator visually observes the actual house corresponding to the house object 32 touched on the map screen 31, selects one of the above 1) to 4) based on the current situation, and inputs the check box object 35 by GUI. Update and save in server 13. When any of the attributes 1) to 4) of the house is changed, the display color on the map screen 31 is also changed. Further, if necessary, the point noticed in the current survey is entered in the memo column of the family register information column 38 (calling and inputting the keyboard GUI screen). Furthermore, if necessary, a new image is acquired using the tablet 11. The acquisition of a new image uses an additional button object 39 in the image 37. In the first embodiment, when the additional button object 39 is GUI-inputted, the shooting function mounted on the tablet 11 by default is activated to enable shooting, and the house object 32 is added as an additional image by shooting using a known shooting method. The real estate information is updated and stored in the server 13.

With such a configuration, the following effects are achieved in the first embodiment.
(1) Since the investigator can update the site information on-site while investigating on-site, there is no need to return to the office and input data, and there is no duplication of work, resulting in reduced work time. Moreover, since the tablet 11 is lightweight, it is advantageous in the operation | work which carries and moves.
(2) Since the corresponding house object 32 on the map can be specified while viewing the current status, it is difficult to confuse, and if the house object 32 on the map is specified, a table 33 on which the corresponding real estate information is automatically displayed is displayed. Therefore, it is no longer possible to apply other real estate information to a certain house by mistake.
(3) Since the family register information field 38 has a memo field, the reason for the unknown house in 3) can also be recorded. The effect of recording in the memo field is the same in the following embodiments.
(4) Since the image photographing function of the tablet 11 can be used, the investigator does not have to carry the camera. This effect is the same in the following embodiments.

<Example 2: Update of standard residential land information>
In the same manner as in the first embodiment, the investigator inputs the URL of the site of the server 13 in advance by a well-known operation so that the tablet 11 can browse the region to be surveyed. Going to the area, the browser of the tablet 11 is activated and the WEB page for updating the standard residential land information is viewed from the display 22. The standard residential land information is information serving as a basis for calculating the prices of all residential land calculated based on the route price, and the tax amount of the surrounding real estate is determined based on the standard residential land price. Standard residential land information is updated once every three years.
FIG. 5 is an example of the WEB page of the second embodiment displayed on the display 22. Here, the table is an input screen on which the investigator contacts (that is, designates) the standard residential land object number 3A49 on the map screen 40 on the display 22 (touch panel 26) and displays real estate information of the standard residential land of 3A49. 42 is displayed (by default, the table 42 is not displayed and becomes a blank area). The tablet 11 is always present at the center of the map screen 40 as in the first embodiment. With the touch, a balloon 43 as a marking appears at the position of the standard residential land 41 of 3A49.

A hold button object 45 and a save button object 46 are displayed at the upper position of the table 42 of the second embodiment. Below these buttons 45 and 46, an image 47 of the designated standard residential land object 41 of 3A49, and a family register information column 48 including the family register information and memo column of the standard residential land are provided. The family register information column 48 can be scrolled up and down. In Example 2, there are items that the investigator can input on the spot and items that cannot be entered in the items in the family register information column 48. In this example, for example, road width, pavement presence, road type, Road system, standard use, current use, most effective use, notes are prepared. The items in the family register information column 48 are displayed as partitioned objects, and the items that can be input are areas in which the object can be directly input using the touch panel 26. For example, as shown in FIG. 5, when a road type that was “prefectural road” before the check is upgraded to “national road” in the current survey, the surveyor is a section object of the road type. By touching 49, a GUI input screen 50 for selecting a road type is popped up and displayed as shown in FIG. Therefore, the researcher newly touches the GUI input screen 50 on the touch panel 26 to select and input “National road”. Then, the type of road is changed from “prefectural road” to “national road”, and the screen is displayed with the color changed in a state where the types before and after the change are arranged in parallel as shown in FIG. As for other items that can be input, it is possible to input that the current status has changed in the same or similar operation. The ability to use the image shooting function of the tablet 11 is the same as in the first embodiment. When the entry of the items in the family register information field 48 is completed, the standard housing lot is updated and saved in the server 13 by touching the save button object 46 and inputting the GUI.
A magnifying glass type icon object 51 is displayed on the left side of the map screen 40. By touching the icon object 51, the researcher can display a list 53 of unexamined (unupdated) standard residential land on the front of the map screen 40 as shown in FIG. 8.

With such a configuration, the following effects are achieved in the second embodiment.
(1) Since the investigator can update on-site while checking the current status of standard residential land information on the spot, there is no need to return to the office and input data, and there is no duplication of work, resulting in reduced work time. . Moreover, since the tablet 11 is lightweight, it is advantageous in the operation | work which carries and moves.
(2) Since the standard residential land object 41 on the corresponding map can be specified while viewing the current status, it is difficult to mistake, and if the standard residential land object 41 on the map is specified, the corresponding real estate information is automatically displayed. Is displayed, so it is no longer possible to accidentally apply another land to a standard residential land.
(3) When the items in the family register information column 48 are changed, before and after the change are written together, the difference between before and after the update is easy to understand.
(4) In the survey of standard residential land spread over a wide area, it is easy to forget to survey, but since a list of unexamined (unupdated) standard residential land can be displayed, such a fear is eliminated.

<Example 3: Update of taxable area information>
As in the first or second embodiment, the investigator inputs the URL of the site of the server 13 by a well-known operation in advance so that the region to be surveyed can be browsed on the tablet 11 and carries the tablet 11 for the survey. Go to the target area, activate the browser of the tablet 11 and browse the WEB page for updating the taxable area information from the display 22. Taxable area information is updated annually to tax land.
FIG. 9 shows an example of the WEB page of the third embodiment displayed on the display 22. Since FIG. 9 is demo software, real estate information is allocated only to the section of the section surrounded by a thick line. In the third embodiment, the investigator touches an arbitrary taxable place mark 54 on the map screen 52 on the display 22 (touch panel 26), and the lot number and the place mark are displayed on the map screen 52 as shown in FIG. The GUI input screen 55 pops up. When the investigator touches the GUI input screen 55, a table 56 serving as an input screen displaying real estate information is popped up on the display 22 as shown in FIG. In the table 56, items such as lot number, taxation classification, taxation item, taxation area, use district, urbanization classification, city planning classification, and memo are displayed. These items include items that can be entered by the investigator on the spot and items that cannot be entered. Items that can be entered (requires input) are the taxable item and the memo. The taxable area is selected from candidates displayed by touching the taxable area button object 57.
When the entry of the taxable area information item is completed, the taxable area is updated and stored in the server 13 by touching the save button object 58 and inputting the GUI.
As shown in FIG. 12, it is possible to display a hatched line on the surveyed ground as a means on the map for determining the difference between the surveyed (updated) texture and the unsurveyed texture according to the setting. .
With such a configuration, the following effects are achieved in the third embodiment.
(1) Since the investigator can update the current status of the taxable area information on the spot, there is no need to return to the office and input data, and there is no duplication of work, resulting in reduced work time. . Moreover, since the tablet 11 is lightweight, it is advantageous in the operation | work which carries and moves.
(2) By touching any taxable area 54 on the map screen 52, the table 56, which is the input screen for the taxable area 54, is displayed and can be input (updated). There will be no application of the texture.
(3) Since it is possible to display an oblique line on the surveyed ground, it can be seen at a glance whether or not a certain area has been surveyed.

The above embodiments are merely described as specific embodiments for illustrating the principle of the present invention and the concept thereof. That is, the present invention is not limited to the above embodiment. The present invention can also be embodied in the following modified form, for example.
In the above-described Examples 1 to 3, the URL is separately input by a well-known operation, and the individual investigation is performed. However, on the tablet 11, by browsing while switching the three WEB pages of Examples 1 to 3. You may make it investigate simultaneously.
-As a survey of information affecting the tax amount of land or buildings, a route survey which is a precondition for calculating a route price can be performed by this system in addition to the above-described Examples 1-3. As for a route, the width, presence / absence of a pavement, presence / absence of a sidewalk, type, etc. are acquired as route information (real estate information) from a corner to a corner as one route. The line price is renewed once every three years.
In the route survey, the investigator also displays the route on the map on the display 22 of the tablet 11 while confirming the current state of the route at the site as in the first to third embodiments. Then, as in the first to third embodiments, an arbitrary route object is touched to display a table displaying real estate information, and the route information is updated and stored in the server 13.
-Since the route price calculated based on the route survey is also real estate information, it may be checked (verified) using this system whether the route price is correct. That is, the investigator can display the route for which the route price is calculated on the map on the display 22 of the tablet 11 while confirming the current state of the route at the site as in the first to third embodiments. Then, a table displaying the route value set by touching an arbitrary route object is displayed, and the route value is updated and stored in the server 13. As a result, the wrongly calculated line price can be corrected locally.

-In the above embodiment, the updated real estate information data is stored on the server 13 side, but is stored in the portable terminal device itself, and the data is stored in the main computer of the office in synchronization after returning to the office. You may make it do.
-In Example 2, the list of uninvestigated (unupdated) standard residential land is displayed. However, in Example 1 and Example 3, unexamined (unupdated) target real estate is also displayed in a list. May be. In addition, a function may be given to display the target property that has already been investigated in this way.
-Although the investigator entered the URL of the site of the server 13 in the tablet 11 in advance, this operation may of course be performed at the site immediately before the investigation.
In the above description, the touch panel 26 is used as an input unit. However, a keyboard, a mouse, a touch pen, or the like connected to the tablet 11 may be used.
Various maps (for example, housing maps and infrastructure maps) are prepared as maps that can be displayed on the display 22 and can be replaced by an investigator's operation, or shown as aerial photographs. You may make it display synchronizing.
-You may make it display on the display 22 so that a researcher's position on the map (namely, the position of the tablet 11) may be shown on the map.
-In addition, it is free to implement the present invention in a modified form without departing from the spirit of the present invention.
