Generating Annual 4-m Land Cover Products over 28 Metropolises in China during 2000-2020

A 4-m fine-grained land cover products over the 28 provincial capital cities in China (mainly in temperate monsoon climate and subtropical monsoon climate zone, and categorized into 7 classes, i.e., cropland, forest, grass, shrub, water, impervious surface, and bare land) is generated through the proposed model; A 4-m annual land cover products during 2000-2020 in Wuhan, China is generated through the proposed model.

To validate the effectiveness of the derived products, three verification approaches are employed. 1) evaluation by the consistency with the contemporary products including 10-m Esri Land Cover, 10-m FROMGLC10, and 30-m GlobeLand30 ; 2) evaluation by the publicly certified 4-m annotation dataset GID; 3) evaluation by the third-party-created annotation samples. The validation results can be viewed in the manuscript, and the reproduction executation details can be viewed at Readme.txt.

The products is in .tif format, and validaiton region is in ENVI/hdr format. Users need to install ENVI software or Arcgis to read the product.
