Problems solved by technology

[0002] The spatial analysis of land survey data and various business result data is widely used in land management-related businesses. However, the graphic segmentation caused by spatial analysis will lead to the area of ​​map patches and linear terrain in the land survey data after spatial analysis. The deduction relationship between the land types between the property areas has changed. If the existing deduction relationship is still used for calculation, the obtained land area and the actual area have a large error

Abstract

The embodiment of the invention provides a land area acquisition method and device and a storage medium, and relates to the technical field of map data; the method includes superposing the spatial analysis layer of the target area with the land type pattern spot layer corresponding to the target area to obtain an area superposing result; obtaining a corresponding ground class pattern spot superposition result and a linear ground object superposition result according to the region superposition result; obtaining an updated deduction relationship according to the linear ground object superposition result; and calculating and obtaining the actual area of the target area according to the ground class pattern spot superposition result, the linear ground object superposition result and the updated deduction relationship. According to the invention, the actual range of the linear ground features and the actual area of the ground pattern spots can be restored on the graph surface through the overlapping operation between the graph layers and the mode of updating the linear ground feature deduction relation, and the accuracy of area analysis is improved.

Description

technical field [0001] The present invention relates to the technical field of map data, in particular to a land area acquisition method, device and storage medium. Background technique [0002] The spatial analysis of land survey data and various business result data is widely used in land management-related businesses. However, the graphic segmentation caused by spatial analysis will lead to the area of ​​map patches and linear terrain in the land survey data after spatial analysis. If the deduction relationship between land types changes, if the existing deduction relationship is still used for calculation, there will be a large error between the obtained land area and the actual area. Contents of the invention [0003] In order to solve the problems existing in the prior art, this application provides a land area acquisition method, device and storage medium, which can restore the actual range of linear features, the actual area of ​​land-type map spots and the actua...
