Digital Raster Graphic -- is a scanned (250 dpi) topographic map of a US Geological Survey (USGS) topographic map including all collar information. The image inside the map neatline is georeferenced to the surface of the earth. The majority (over 95%) of DRGs with collars are in a UTM NAD 27 (Zone varies depending upon location), However there are a small amount in NAD 83.

Collarless DRGs have all non-map information removed and are projected into Latitude-Longitude. These maps may be mosaiced to create a seamless map covering much larger areas.
