I am having difficulty downloading and working with NED elevation rasters the USGS publishes via it's "National Map."
http://nationalmap.gov/viewer.html Does anyone know how to: 1: Schedule a download of all the elevation tiles in a particular state? 2: Convert the ArcGrid files provided by the system into TIF or DEM files that gdal can use to create hillshade, slopeshade and color relief? Thank you.
