The Export DEM command allows the user to export any loaded elevation grid data sets to a native format USGS DEM file.
When selected, the command displays the DEM Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the quadrangle name, grid spacing and vertical units, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
