Development of a national seamless database of topography and hydrologic derivatives Development of a national seamless database of topography and hydrologic derivatives
The recent completion of the National Elevation Dataset (NED) and the National Hydrography Dataset (NHD) has provided an avenue for nationwide development of topographically derived hydrologic data layers at a scale of 1:24,000. This multilayer dataset of hydrologic derivatives, entitled the Elevation Derivatives for National Applications (EDNA), is being developed by a consortium of...
