LBA Regional Land Cover from AVHRR, 1-km, Version 1.2 (IGBP)

In addition, a core set of derived thematic maps produced through the aggregation of seasonal land cover regions are included in each continental data base. The continental data bases are combined to make six global data sets, each representing a different landscape based on a particular classification legend. The following derived data sets are included in the global land cover data base:

• Global Ecosystems (Olson, 1994a, 1994b)
• IGBP Land Cover Classification (Belward, 1996)
• U.S. Geological Survey Land Use/Land Cover System(Anderson & others, 1976)
• Simple Biosphere Model (Sellers and others, 1986)
• Simple Biosphere 2 Model (Sellers and others, 1996)
• Biosphere-Atmosphere Transfer Scheme (Dickinson and others, 1986) The legends for each of these derived data sets can be found in the documentation accompanying the data. For a description of the methodology for the global data base, see the global readme file found under the EROS Data Center DAAC home page (edcwww.cr.usgs.gov/landdaac/glcc/glcc.html).
