Topographic map - DRG

This is a map taken from a DRG or
digital raster graphic - a scanned image of a U.S. Geological
Survey (USGS) standard series topographic map.


A topographic map has contour lines which represent elevation and relief of an area. This one is of Carter Lake, GA, where a group of friends and I recently went camping.
