The data set is 1:700000 land cover data set of Xinjiang Uygur Autonomous Region in Northwest China in 1990. This data adopts a hierarchical land cover classification system. The first class of the classification system is consistent with the IPCC system, with a total of 6 categories (woodland, grassland, wetland, cultivated land, artificial surface, others), and the second class uses 38 types with global unified code generated by the LCCs of FAO.
The main data sources are as follows: 1. Land use data of 1990s; 2. Landsat fine correction of false color composite images of counties in the same period with land use data; 3. Auxiliary data include 1:500000 grassland resource map (vector), 1:1 million soil type map (vector), 1:1 million vegetation type map (scanning)
Based on ecognition software platform, object-oriented classification method is adopted
The data quality is good
