This point shapefile represents 38 terrestrial laser scanner (TLS) survey scan locations collected by single-base real-time kinematic (RTK) global navigation satellite system (GNSS) surveys in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. Data were collected by two Topcon GR-3 GNSS receivers at one-second intervals for three minutes for each location.
This polygon shapefile represents estimated flood-inundation areas in Grapevine Canyon near Scotty's Castle, Death Valley National Park. Estimates of the 4, 2, 1, 0.5, and 0.2 percent annual exceedance probability (AEP) flood streamflows (previously known as the 25, 50, 100, 250, and 500-year floods) were computed from regional flood regression equations. The estimated flood streamflows were used with one-dimensional hydraulic models to compute water surface elevations that were mapped on a digital terrain model of the study area. Those locations where the water surface was higher than the land surface were defined as inundated. The inundation polygons are named by AEP flow (4, 2, 1, 0.5, 0.2-percent) and geometry...
This point shapefile represents ground observations collected by terrestrial laser scanner (TLS) surveys in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016, and filtered of extraneous data from features such as vegetation, fences, power lines, and atmospheric interference using an iterative process in I-Site Studio. The resulting 122,104 points were used to produce a digital terrain model of the area (GrapevineCanyon_TIN.zip in this data release).
This zipped folder contains all relevant files to document and run the Hydrological Engineering Center-River Analysis System (HEC-RAS) one dimensional hydraulic model used to simulate flood inundation extents in Grapevine Canyon near Scotty's Castle, Death Valley National Park. Specifically: 1) model-software-version.txt (file) Identifies the modeling software version and website. 2) modelgeoref.txt (file) Includes reference to the model documentation report, data release, and bounding box coordinates. 3) model_run_files (folder) Contains files that were used to run the model. 4) model_output (folder) Contains selected model outputs from the model runs. 5) calibration-targets (folder) Contains high-water marks from...
This zip file contains 42 LAZ point cloud files surveyed by terrestrial laser scanner (TLS) from 38 locations in Grapevine Canyon near Scotty’s Castle, Death Valley National Park, from July 12-14, 2016. Data were collected by 360-degree scans using a Maptek I-Site 8810XR TLS and post-processed with I-Site Studio software.
This point shapefile represents four static reference locations collected by single-baseline Online Positioning User Service – Static (OPUS-S) global navigations satellite system (GNSS) surveys in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. Surveys were completed at three Federal Highway Administration benchmarks (FHWA) and one temporary reference point, Rebar1. Data were collected using Topcon GR-3 and Leica Viva GS14 GNSS receivers on two-meter fixed height tripods. Processing of static observations was done using the National Geodetic Survey (NGS) Online Positioning User System (OPUS).
This U.S. Geological Survey data release consists of a polygon geospatial dataset representing estimated flood-inundation areas in Grapevine Canyon near Scotty's Castle, Death Valley National Park, and the data acquired and processed to support the delineation of those areas. Supporting datasets include topographic survey data collected by global navigation satellite system (GNSS) and terrestrial laser scanner (TLS) in Grapevine Canyon from July 12-14, 2016; derivatives of those data; pebble count data collected in Grapevine Canyon; and an archive of the one-dimensional hydraulic model used to generate the flood-inundation area polygons. Specifically: 1)a point dataset of four static reference locations (StaticGNSS_x)...
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.
This comma-separated values (CSV) file includes the results of five Wohlman-style pebble counts (Wolman, 1954), collected in Grapevine Canyon near Scotty's Castle, Death Valley National Park, on March 2, 2017. Pebble counts were performed to determine the size of channel bed particles and evaluate channel roughness to be input into a one-dimensional hydraulic model.

This zip file contains a digital terrain model represented by a triangulated irregular network (TIN) derived from filtered ground observations collected by terrestrial laser scanner (TLS) in Grapevine Canyon near Scotty's Castle, Death Valley National Park, July 12-14, 2016.
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).
