Georgia Digital Raster Graphic Hillshade (DRG243D)

US Geologic Service (USGS) Digital Raster Graphics (1:24000 scale) for the State of Georgia, combined with a hillshade visualization of a 10 meter Digital Elevation Model (DEM). A DRG is an image of a USGS standard series topographic map scanned at a minimum resolution of 250 dots per inch, and georeferenced to the Universal Transverse Mercator (UTM) projection. Each 7.5-minute DRG provides coverage for an area of land measuring 7.5-minutes of latitude by 7.5-minutes longitude. The horizontal positional accuracy and datum of the DRG matches that of the source map. The National Elevation Dataset (NED) is produced and distributed by the USGS. The NED is derived from diverse sources and processed to a common coordinate system and unit of vertical measure. NED data are in geographic coordinates (decimal degree units) and conform with the North American Datum of 1983. Elevation values are in meters, and referenced to the North American Vertical Datum of 1988 over the conterminous US. Although these data have been processed successfully on a computer system at the Georgia GIS Data Clearinghouse, no warranty expressed or implied is made by Georgia GIS Data Clearinghouse regarding the utility of the data on any other system, nor shall the act of distribution constitute any such warranty.
