JP2000076349A - Acquiring system of sample on land price map - Google Patents

Abstract

PROBLEM TO BE SOLVED: To decide a reliable value which can actually be adopted by displaying prices concerning an integrated land on a map as entire Japan integrated map information and unitarily managing them. SOLUTION: The address, the use area and the road situation of a desired land and the scope of the area of the land are inputted. A central processor receives the instruction of a main memory control program, extracts data on the address, the acreage, the use area and the land area of neighborhood whose condition is equal to that of the desired land from a unitary land price example data file and enters a circle on a map to symbolically mark-display a published price, a bank evaluation, etc., as peripheral data of a desired land. A land evaluating system obtains an average value and a center value based on obtained data. Finally, a reference land, a route price, a comparing price, a center land location and an average value displayed on a land price deciding screen are totally judged to decide a land price. Then, the individual factor coefficient of the desired land is multiplied to this land price to obtain a final price.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention shows the unit price of land as a sample of past land prices, captures the data statistically and empirically, and calculates the price of land that is credible as an economic value by computer processing. It relates to a land price map sample acquisition system to be determined.

[0002]

2. Description of the Related Art Each land price data is described on a paper-based map with an information position, and detailed contents are accumulated as a separate document and used in a limited range. You can see map processing by computer, but it only shows where the land evaluation point is, and there is data that clearly shows the land price, but it does not include various conditions as data elements The fact is that only parts are managed.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to clarify a large amount of land price data as a database on a map, and to sample the data from a drawing to obtain a credibility that can be practically adopted as a land price. The present invention provides a system for acquiring a sample on a land price map which determines a certain value of the land price.

[0004]

SUMMARY OF THE INVENTION A land price map sample acquisition system according to the present invention is an example of a past sale price of land, an example of a public land acquisition price, an example of a land appraisal price, an example of an auction price of land, and a financial institution. Examples of land evaluation prices and land prices announced by government agencies, such as published prices, prefectural standard prices, and route prices, are attached with information for each purpose, and prices for those lands are indexed using location numbers and land location information as a database. The processing for accumulation and the prices for the accumulated land are displayed on a map as unified map information in Japan and managed in a unified manner.

Further, in the land price map sample acquisition system according to the present invention, in claim 1,
By clicking on the symbol that is displayed symbolically, such as rating, competition, etc., with a mouse or the like, the type of information that is land price example information, the area of use, road conditions, surrounding conditions, contents 1,
Content 2, contents of each land price example such as current land price, land evaluation price, land evaluation date, etc. are extracted from a database file and displayed directly on the screen.

Further, in the land price map sample acquisition system according to the present invention, in claim 1 or 2, a line is drawn on the map screen, and the land map price data in the frame is used as sampling data for land evaluation. It's something you get for.

The system for acquiring a sample on a land price map according to the present invention includes a condition number, a land area, a zone of use, a street situation, a surrounding situation, a land area size, and other conditions that affect the price of the land. Data matching the extraction conditions is extracted from the land price unit price database file, and the surrounding data of the target land valuation land is displayed on the map, including the posted land prices, actual land sales and purchases, land bank evaluations, etc.
The mark is displayed symbolically with a circle.

[0008] The route price of the corresponding location is manually input, but is multiplied by a preset coefficient for each municipality and used as a reference value.

[0009] In order to facilitate automatic updating of the land price of the corresponding evaluation land at a later date, a public land or a prefectural standard land is selected from the map as a reference land and is set as a reference land. The published land of the selected land or the prefectural reference land is multiplied by a coefficient for each municipalities which is set in advance as in the preceding paragraph, to obtain a comparative price. In addition, by storing in advance the route price of a publicly known place or a prefectural standard place in the data of a publicly known place or a prefectural standard place, the land price of the relevant evaluation place can be obtained in proportion.

[0010] The price data on the various past lands marked is clicked with a mouse or the like, and the contents of the price data are confirmed, and then it is determined whether to adopt as sample data or not.

A range is drawn on the map displayed on the screen with a mouse or the like to secure land price data. Based on the land price data obtained as described above, a land evaluation system (Japanese Patent Application No. 9-1) already filed by the applicant
41130).

An average value and a median value are calculated by the land evaluation system. That is, means for inputting the location, land area, land area, land use, road condition, topography and environmental conditions of the land to be sought, land price unit data recording means for recording land price unit data, and land area unit price file Or, based on past price examples in administrative divisions such as Chome,
A means for extracting data belonging to a given extraction period and a use area and an extraction location set as conditions as necessary, a correction rate set in advance by a user of this system is calculated in reverse as a unit price of processed land, A means to determine the standard land unit price,
The correction items record the general items of the published price of land, the standard price of prefectural reference land, and individual items of environmental conditions such as the size of land area, the status of roads, the topography, the presence or absence of sewerage, and the distance from schools. The appropriate land price is determined by the correction means selected and adopted. A simple average land unit price calculating means averaging based on each of the obtained processed land unit price examples, and a median land unit price calculating means obtained for the purpose of eliminating the extremes of each of the processed land unit price examples; If there is a great difference between the land unit price and the median land unit price, it is a land evaluation system that determines at a glance that there is a variation in the data and obtains an appropriate land unit price.

The data obtained by the above operation is displayed in a list according to the price, and the inappropriate data is excluded with reference to the average value and the median value.

Finally, the land price is determined by comprehensively judging the reference land, the route price, the reference price, the median value and the average value displayed on the land price determination screen.

[0015] The land price of the corresponding land is determined by multiplying the obtained land price by an individual factor coefficient such as depth, sunshine duration, sewer burial and the like, which are individual factors of the land.

[0016]

[Function] A process of accumulating a land price unit price database containing coordinate values and the like for enabling a specified place on the whole map to be specified on a map in units of administrative divisions such as a large section or a street. Data around the desired land price is selected and extracted, and the land price is determined in consideration of the average value of the extracted data and the following conditions. The public price, prefectural standard land standard price, etc. as general elements, roads and land environment as individual elements (situation, topography, direction of roads, land shape, traffic conditions, water supply status, sewerage status, gas installation status, Land prices are determined by counting and multiplying all of the usage right status (ownership, land right, lease right) adjacent to public facilities, distances to shops, etc. (method of scoring and percentage of some conditions, etc.).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a system configuration diagram of a land price unit price prediction device in a land price map sample acquisition system according to the present invention, and FIG. 2 is a flow of processing for executing the system.

First, the location number of the land, the area of use, the road condition, the surrounding conditions, and the size of the land area, which are obtained from an input device such as a keyboard, are set.

The basic processing of the land price map sample acquisition system is as follows. The central processing unit receives instructions from the control program of the main memory, and extracts data on the neighboring location number, land area, restricted area, street conditions, surrounding conditions, and land area that are the same as the required land from the land price unit price example data file. And, as data around the destination
The published price, actual sales examples, bank evaluations, etc. are marked symbolically with a circle on the map.

The route price of the corresponding location is manually input, but is multiplied by a preset coefficient for each municipality and used as a reference value. In order to facilitate automatic updating of the land price of the corresponding evaluation land at a later date, the reference land is determined by multiplying the published land or the prefectural reference land by the coefficient set for each municipalities in the same manner as in the preceding paragraph, to obtain a comparative price. In addition, by storing in advance the route price of a publicly known place or a prefectural standard place in the data of a publicly known place or a prefectural standard place, the land price of the relevant evaluation place can be obtained in proportion. Click the marked past data to check the contents of the data and decide whether to adopt it as sample data or not. Draw a range on the map with the mouse to secure the data.

Based on the data obtained as described above, the present applicant transfers the data to a land evaluation system for which a patent application has already been filed. Calculate the mean and median using the land assessment system described above.

The data obtained by the above operation is displayed in a list according to the price, and the inappropriate data is excluded with reference to the average value and the median value.

Finally, the land price is determined by comprehensively judging the reference land, the route price, the reference price, the median value and the average value displayed on the land price determination screen. The land price is determined by multiplying the obtained land price by individual factors such as depth, sunshine hours, sewer burial, etc., which are individual factors of the land.

[0024]

According to the present invention, a large amount of land-related information is stored in a database, and symbolic marks can be displayed on a map by symbolic display, thereby enabling individual land price map samples to be checked in a pop-up display and statistical sample data. Can be secured directly by enclosing a frame on the screen, and real-time judgment can be realized by visible operation. The contribution to the real estate industry, financial industry, and public sales, which require the streamlining of office work and the liquidation of real estate that can be obtained by instantly determining near-equal land prices without human deviation, can be greatly expected.
