Resource Abstract:
- description: The Louisiana Digital Elevation Dataset was derived from the U.S. Geological Survey National Elevation Database
(NED). This data was projected to Universal Transverse Mercator Zone 15, NAD83. The vertical units have been converted from
meters to feet. The U.S. Geological Survey 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.; abstract: The Louisiana Digital
