%X This dataset is selected from the Landsat satellite orbit images of Naiman (P121R030), Dunhuang (P137R032), and Minqin (P131R033) counties, with a typical area of 125 * 125km2. Landsat series satellite images are used as the data source, and an object-oriented classification method combined with a 1:100000 scale mapping requirement is used to conduct thematic mapping of desertification in the six periods from 1975 to 2024. The data format is Shape file, and the projection system adopts ALBERS equal area projection based on WGS84 benchmark. The Classname field in the attribute table is the desertification code.
