The source data is described below:\nThe U.S. Geological Survey has developed a National Elevation Dataset (NED). \t\tThe NED is a seamless mosaic of best-available elevation data. The 7.5-minute \t\televation data for the conterminous United States are the primary initial source \t\tdata. In addition to the availability of complete 7.5-minute data, efficient \t\tprocessing methods were developed to filter production artifacts in the existing \t\tdata, convert to the NAD83 datum, edge-match, and fill slivers of missing data \t\tat quadrangle seams. One of the effects of the NED processing steps is a \t\tmuch-improved base of elevation data for calculating slope and hydrologic \t\tderivatives.
