Summary
This point shapefile represents 769 locations surveyed by single-base real-time kinematic (RTK) global navigation satellite system (GNSS) in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. The points were collected at 3-second intervals and include hard and soft surfaces and slopes throughout the study area. The points were used as vertical precision verification for a terrestrial laser scanner (TLS) survey.

The points were used as vertical precision verification for a terrestrial laser scanner (TLS) survey.
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.
