description: This HILLSHADE Model was derived using the HILLSHADE tool in ArcGIS 9.2. The source data is described below: The U.S. Geological Survey has developed a National Elevation Dataset (NED). The NED is a seamless mosaic of best-available elevation data. The 7.5-minute elevation data for the conterminous United States are the primary initial source data. In addition to the availability of complete 7.5-minute data, efficient processing methods were developed to filter production artifacts in the existing data, convert to the NAD83 datum, edge-match, and fill slivers of missing data at quadrangle seams. One of the effects of the NED processing steps is a much-improved base of elevation data for calculating slope and hydrologic derivatives. The specifications for the NED 1 arc second and 1/3 arc second data are: Geographic coordinate system Horizontal datum of NAD83, except for AK which is NAD27 Vertical datum of NAVD88, except for AK which is NAVD29 Z units of meters NOTE: MONTEREY COUNTY STAFF HAS REPROJECTED THIS DATA TO CA STATE PLANE ZONE 0404 (SURVEY FEET), AND CONVERTED THE Z VALUES TO TO U.S. SURVEY FEET.
