DRG (digital raster graphic) is a digitally scanned image of a U.S. Geological Survey (USGS) standard series topographic map. They normally include the original border information, or "map collar." The image is georeferenced to the surface of the earth and fit to the Universal Transverse Mercator (UTM) projection. DRGs are commonly used in GIS applications. This DRG shows Depoe Bay Port and Harbor in Lincoln County, OR.
