DRG Digital Raster Graphic by GeoMart
. Geological Survey (USGS) topographic map.. Most USGS 7.5-minute DRGs produced between 1995 and 1998 have the following specifications: The source material for a DRG is a USGS topographic paper map.. The digital image is accompanied by a metadata file that complies with the Federal Geographic Data committee's "Content Standards for Digital Geospatial Metadata" (June 8, 1994).. In most cases, errors in the DRG are small compared with sources of error in the original map graphic.. A USGS DRG has a standard color palette of 13 colors, intended to model the line-drawing nature of the source graphic.. Most DRGs made by scanning paper maps contain significant amounts of color noise, especially in areas filled by lithographic screen tints.
