Global Landuse USGS

Global Land Cover Characterization (GLCC) (Global_Landuse_USGS) is a land cover classification dataset based primarily on the unsupervised classification of 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 (Link). The GLCC contains 22 numerical classes corresponding to specific land cover types. Associated files include: "Lookup_Landuse_USGS.txt", and "SWAT2012.mdb". Download related article from "Nature Scientific Data":
