The data set is 1:700000 land cover data of Gansu Province in Northwest China in 2005. 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 in 2005; 2. False color synthetic images of counties accurately corrected by Landsat in the same period of land use data; 3. Auxiliary data include 1:500000 grassland resource map (vector), 1:1000000 soil type map (vector), 1:1000000 vegetation type map (scan), etc.
Based on ecognition software platform, object-oriented classification method is adopted
The data quality is good
