Geographic Information Systems (GIS) : Land Use and Land Cover

A variety of data and reports related to wetlands.

The GAP national land cover data, based on the NatureServe Ecological Systems Classification, are the foundation of the most detailed, consistent map of vegetative associations ever available for the United States.

Using the EROS FOREcasting SCEnarios of Land-Cover (FORE-SCE) model, EROS scientists are modeling land-cover change both into the future, using scenario-based modeling approaches, and for "backcasting" land cover for historical periods. In combination with USGS remote sensing based land-cover data, EROS' modeling efforts result in consistent, annual land-cover maps from 1938 through 2100, with multiple scenarios of potential land cover for future periods.
