Abstract

The invention provides a cross-checking method and a cross-checking device for land coverage remote sensing products. The cross-checking method and the cross-checking device relate to the technical field of land coverage remote sensing. The cross-checking method for the land coverage remote sensing products defines two error indexes of a mean square root error and a correlation coefficient based on covariance, and obtains an error of each type of each variety of land coverage remote sensing products relative to real land coverage distribution through comparing three varieties of land coverageremote sensing products obtained independently. The cross-checking method for the land coverage remote sensing products improves the efficiency of checking the land coverage remote sensing products, reduces the checking cost, and can realize full coverage checking of the land coverage remote sensing products.

Description

technical field [0001] The invention relates to the technical field of land cover remote sensing, in particular to a method and device for cross-checking land cover remote sensing products. Background technique [0002] In recent years, remote sensing technology has been widely used in different industries and fields, and land cover mapping is a traditional and advantageous field of remote sensing applications. Obtaining land cover products through remote sensing technology has become the main method for human to monitor land use and ecological environment. In order to ensure the healthy development of the industry and promote the quality of land cover remote sensing products, it is urgent to strengthen its authenticity inspection. [0003] Generally, experimenters can obtain the real land cover status of a certain sample size in a certain area through field surveys, and then compare the field survey results with the land cover products obtained by remote sensing, so as to k...
