Cultivated land requisition-compensation space auditing method and device

Abstract

The invention is applied to the field of cultivated land resource management, and provides a cultivated land requisition-compensation space auditing method and device. The method comprises the steps that multiple to-be-overlaid layers are acquired, wherein each to-be-overlaid layer comprises vertex coordination information; the to-be-overlaid layer with the largest area in the to-be-overlaid layer is acquired; spatial overlaying is conducted on the to-be-overlaid layer with the largest area and an occupied layer, and the area of the overlaying part of the layers and the corresponding cultivated land quality grades are acquired; spatial overlaying is conducted on the remaining non-overlaid to-be-overlaying layers and the occupied layer, and the area of the overlaying part of the layers and the corresponding cultivated land quality grades are acquired; the area of the overlaying part of the layers and the corresponding cultivated land quality grades are matched with a compensation layer, and auditing information comprising a matching result is output. In this way, the spatial area of the data overlaying parts of the layers is accurately calculated, and therefore the auditing efficiency and precision can be improved.

Description

technical field [0001] The invention belongs to the field of cultivated land resources management, and in particular relates to a method and device for reviewing occupied and supplemented space of cultivated land. Background technique [0002] Cultivated land is the basic resource for human survival and development, the basic element of grain production capacity, and the cornerstone of national food security. In recent years, with economic and social development, urbanization has accelerated, and constraints on cultivated land resources have tightened. In the face of the current severe situation of cultivated land resources, strengthening the protection of cultivated land with "equal emphasis on quantity and quality" and strict balance management of cultivated land occupation and compensation are the important basis for ensuring national food security and promoting the healthy development of agriculture under the new situation. An important task of the strategy of storing f...

Problems solved by technology

[0005] The present invention provides a method and device for reviewing cultivated land occupation and compensation space, aiming to solve the problem of precise errors that are prone to occur due to the use of single-layer superimposition combined with manual measurement to obtain the superimposed area by sequentially superimposing cultivated land layers in actual operation and low efficiency
