- Abstract: The SGID contains complete statewide coverage of scanned standard series USGS topographic maps, also known as digital raster graphics (DRGs). AGRC has modified these DRGs so that they are collarless and are georeferenced to the surface of the earth using the UTM Zone 12 North, NAD83 projected coordinate system (except where noted). Every product on this page should be downloadable from raster.utah.gov. For all available USGS Topographic Maps visit The National Map TNM Download page or topoView.

Vintage
The Utah Geological Survey created digital 7.5, 15 and 30-minute vintage U.S. Geological Survey topographic quadrangle maps (1900-1966) by scanning original paper maps at a resolution of 500 dots per inch (dpi). These digital scans were enhanced in Adobe Photoshop as needed. Subsequent 16 point spline georeferencing was done in ArcMap. There is not a statewide collection of these vintage topographic maps and they have a NAD27 Datum.
