Title: DRG 100K (Digital Raster Graphics, 1:100,000, USGS)
Description
Abstract: Data available online through the University of Arkansas Spatial Library at http://www.cast.uark.edu/UASL. The Digital Raster Graphic (DRG) is a raster image of a scanned USGS topographic map, georeferenced to the UTM grid. This layer was created by GeoSurf.
Purpose: A DRG is useful as a source or background layer in a GIS, as a means to perform quality assurance on other digital products, and as a source for the collection and revision of DLG data. DRG's can also be merged with other digital data, e.g. DEM's or DOQ's, to produce a hybrid digital file.
