DEM data for 1-degree units are collected from topographic map sources, ranging from the 7.5-minute map series to the 1- by 2-degree map series, or from photographic sources by using image correlation systems.
DEM data are produced by the National Imagery and Mapping Agency (NIMA) in l- by 1-degree units that correspond to the east or west half of the USGS 1- by 2-degree topographic quadrangle map series (1:250,000-scale) for all of the United States and its territories.
DEM data accuracy is derived by comparing linear interpolation elevations in the DEM with corresponding map location elevations and computing the statistical standard deviation or root-mean-square error (RMSE).
