The data of land-use in Jiangyin and Shunde is based on landuse maps of Jiangyin and Shunde in 2001 and 2010 when theircity master plans were created and later revised. The plan-makingteam firstly obtained the topographic map at a 10,000 scale, andthen made site-to-site investigations to verify the land use type ofeach non-agricultural plot. Compared with Landsat thematic map-per (TM) satellite images, the resolution of the land use map is muchhigher, and the map can provide detailed information of land usetypes.
