Global Land Cover for SWAT "Global Landuse USGS"

The GLCC from USGS is a landuse and land cover classification dataset based primarily on the unsupervised classification of the 1-km AVHRR (Advanced Very High-Resolution Radiometer) 10-day NDVI (Normalized Difference Vegetation Index) composites. The AVHRR source imagery dates from April 1992 through March 1993. The GLCC map contains 24 land cover types. Correspondence is made between the GLCC units and SWAT crop database based on the description of the land covers provided by the maps and the SWAT landuse definitions. The databases for the above two global landuse maps are supported by the table crop in the SWAT2012.mdb database and the lookup tables “Lookup_Landuse_Globcover.txt” and Lookup_Landuse_USGS.txt. The SWAT2012.mdb and look up tables could be downloaded in https://www.2w2e.com
