Summary
This polygon shapefile represents filters used with I-Site Studio software to filter ground observations collected by terrestrial laser scanner (TLS) survey in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. Filters were used to remove extraneous data from features such as vegetation, fences, power lines, and atmospheric interference. The resulting points were used to produce a digital terrain model of the area (GrapevineCanyon_TIN.zip in this data release).

These data were collected as part of a U.S. Geological Survey study, done in cooperation with the National Park Service, to assess the extent of potential flood-inundation areas in Grapevine Canyon near Scotty's Castle, Death Valley National Park, California. Regional flood regression equations were used to estimate the 4, 2, 1, 0.5, and 0.2 percent annual exceedance probability (AEP) flood streamflows. The estimated flood streamflows were used in the one-dimensional hydraulic model to compute water surface elevations mapped using the digital terrain model.
