Summary
Abstract: The Selawik National Wildlife Refuge USGS digital data set contains land cover
classifications for the Selawik National Wildlife Refuge. The data is derived
from Landsat MSS data and elevations as well as slope and aspect data derived
from DEM data. Data can keyed to a U.S. Geological Survey 1:250,000
quadrangle. Spatial referencing is by 50-meter grid cells. Data sources are
Landsat MSS data and Digital Elevation Model (DEM) data. The data set includes
101 records. Storage required varies by storage medium and selected area. The
file structure is sequential. Data are available online The data is organized
by 7 1/2 ' or 15 ' quads.
