Nevada sand dunes.

Very incomplete, compilation in progress. Most relevant features south of latitude 39°-40°N have been captured, and attributes populated when known. North of that, only features visible on the 1998 GAP Land Cover 30-m grid data have been captured in rough form, and review, capture, refinement, and attribution of mapped features remains to be done.

When complete, these data will include all sand dune features depicted on current 1:100,000 topographic maps, plus some major features depicted only on 1:24,000 topographic maps. Compilation began by on-screen capture of sand dune areas depicted in the 1998 Nevada GAP Land Cover 30-m grid data. The 1:100,000 DRG topographic maps covering Nevada were then reviewed on-screen in series from south to north and from east to west. Boundaries of GAP-indicated features were refined, and all other mapped dune features were digitized on-screen and attributed. In some cases, major known dune features were captured and/or further refined using 1:24,000 DRG topographic maps.
