Quantification of Landscape Indicators/Aquatic Resource Associations in the Savannah River Basin
DATA SETS USED
The spatial data sets used are obtained from a variety of sources. The primary data sets used in this landscape assessment include: Multi Resolution Land Characteristics (MRLC) Interagency Consortium land cover/land use (Bara, 1994), State Soil Geographic data base (STATSGO) soils (Natural Resources Conservation Service, 1996), RF3 streams (U.S. EPA, 1997), USGS 8-digit HUCs, Georgia and South Carolina subbasins, Region 4 sampling site locational and sampling data, 30-m and 100-m digital elevation models (DEM; USGS, 1990), digital line graph (DLG) roads (USGS, 1989), and National Inventory of Dams impoundments (U.S. Army Corps of Engineers, 1997). Landscape change assessment used North American Land Characterization (NALC) imagery from the 1970s and 1990s (U.S. EPA, 1993). Data sets were subset to the area of interest using the basin boundary coverage.
