Description
The Australia/Pacific land cover data base is one portion of a global land cover characteristics data base that was developed on a continent-by-continent basis. All continents in the global data base share the same map projections (Interrupted Goode Homolosine and Lambert Azimuthal Equal Area), have 1-km nominal spatial resolution, and are based on 1-km AVHRR data spanning April 1992 through March 1993 (Loveland and others, 1999). Each continental data base has unique elements that are based on the salient geographic aspects of the specific continent. 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. These are:
-
Global Ecosystems (Olson, 1994a, 1994b)
-
IGBP Land Cover Classification (Belward, 1996)
-
U.S. Geological Survey Land Use/Land Cover System (Anderson and 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)
-
Vegetation Lifeforms (Running and others, 1994)
