Digital Raster Graphics (DRG) are scanned versions of U.S. Geological Survey topographical maps. The area within the neat line of the image is georeferenced so GIS information can be over-layed on the DRG image. This map is of a small portion of Austin, Texas. It shows several building outlines, property boundaries, roads, and rivers. This map could serve as a base for statistical data of the Austin area.
