| DATA_SET_DESCRIPTION |
Data Set Overview : This archive contains DEMs acquired in September 2003 by the Wallops/ GSFC Airborne Topographic Mapper, a scanning laser altimeter. The data were acquired at three locations in Nevada: Sedan crater, in the northern part of Yucca Flats, Schooner crater, in the northwestern part of the Nevada Test Site, and Buckboard mesa (Danny Boy crater), in the western part of the Nevada Test Site. The data consist of three vector data files and three DEM flat files, each with an accompanying detached PDS label. The three DEM flat files also have detached ENVI headers containing geographic data. The vector files list the longitude in degrees, the latititude in degrees, and the elevation in meters above datum as floating point values. The vector data were rasterized with ENVI to 2x2 m spacing and projected to UTM coordinates. In the resultant DEM flat files, the pixels are floating point values in meters above the datum. For the vector data: horizontal datum : WGS84 Ellipsoid vertical datum : ITRF94 For the raster data: horizontal datum : WGS84 Ellipsoid vertical datum : NAD27 All three datasets were generated from multiple flight lines.
