This data set provides the geographic distributions of 17 classes of land cover based on the International Geosphere-Biosphere Program Data and Information System's (IGBP-DIS) DISCover land cover (Loveland and Belward 1997) and 15 classes of the Simple Biosphere(SiB) model processed at the United States Geological Survey (USGS) Earth Resources Observed and Science (EROS) Data Center (EDC). There are six zip files compiled according to land cover classification scheme (IGBP DISCOVER and SiB), and spatial resolution (one-, half-, and quarter-degree), each containing data files in standard ESRI ArcGIS ArcInfo ASCII Grid format for each land cover class and the dominate landcover class.
The objective of this study was to create a land cover map derived from 1 kilometer AVHRR data using a full year of data (April 1992-March 1993). This thematic map was resampled to 0.25, 0.5 and 1.0 degree grids for the International Satellite Land Surface Climatology Project (ISLSCP) data initiative II. During this re-processing, the original EDC land cover type and fraction maps were adjusted to match the water/land fraction of the ISLSCP II land/water mask. These maps were generated for use by global modelers and others.
