Method and device for evaluating land value based on big data

Abstract

The invention provides a method and device for evaluating land value based on big data. The method and the device are used for improving the reference value of a land value evaluation result. The method comprises the steps of obtaining big data of a to-be-evaluated region; converting the POI longitude and latitude data into plane coordinate data, and dividing the plane coordinate data into a plurality of grids according to a preset size to obtain POI grid data; matching each merchant in the map data to a corresponding grid in the POI grid data to obtain merchant distribution data; according tothe merchant distribution data, determining a relative position of each grid in the to-be-evaluated region and a reference merchant in each evaluation index in the plurality of evaluation indexes, and according to the relative position, determining a score of each grid in the to-be-evaluated region corresponding to each evaluation index in the plurality of evaluation indexes; and according to theweight of each evaluation index in the plurality of evaluation indexes, carrying out weighting processing on the score of each evaluation index corresponding to each grid in the to-be-evaluated region to obtain a land value score of the to-be-evaluated region.

Description

technical field [0001] This application relates to the field of computer technology, in particular to a method and an evaluation device for evaluating land value based on big data. Background technique [0002] The land value is the reference for the development and auction land price. Currently, the existing methods for assessing the land value generally use manual evaluation of the land value. The method of manually evaluating land value generally adopts the market comparison method. This market comparison method compares the land price to be evaluated with the land price that has recently been traded, and corrects the land value of the land to be evaluated based on the land price that has been traded. value. [0003] In the market comparison method, the user needs to first obtain the price of the land that has been traded in the near future, but different users have different experiences, and different people evaluate, and the result of the revised land value of the land...

Problems solved by technology

[0003] In the market comparison method, the user needs to first obtain the price of the land that has been traded in the near future, but different users have different experiences, and different people evaluate, and the result of the revised land value of the land to be evaluated will be different.
