Terrestrial Light Detection and Ranging Topographic Survey Data for Two Recreation Areas Near Blue Mountain Lake and Nimrod Lake, Arkansas, March 2020
The U.S. Geological Survey collected topographic data in cooperation with the U.S. Army Corps of Engineers to assist in the management of two recreation areas at Blue Mountain Lake and near Nimrod Lake in Arkansas. Data were collected March 3-4, 2020 using terrestrial light detection and ranging (T-lidar) surveying equipment, Global navigation Satellite System (GNSS) surveying equipment, and conventional surveying techniques. The surveyed locations had a parking area, boat ramp, and some small recreational structures. Each site was surveyed using a FARO 3D tripod-mounted T-lidar unit. Additionally, a topographic survey was conducted in order to georeference the lidar survey. These topographic data were collected...

The following spreadsheets contain total station survey data. These spreadsheets contain topographic cross section information including: the raw data collected from total station surveys (including point ID, X, Y, and Z coordinates), and post-processed distance and elevation data with a graph of each cross section. Each sheet contains tabs labeled 'A' for Anderson Creek, 'B' for Boulder Creek, 'C' for Canyon Creek, and 'J' for Jack Creek. In each case, the number corresponds to the reach number (1-4). 'XS' stands for cross section. Slope' denotes tabs that contain topographic information about the Thalweg and Water Surface slopes along each reach for multiple total station set-ups (all denoted). The point data...

Surveyed peak-stage elevations, coordinates, and indicator data of strandlines from large floods on the Colorado River in Grand Canyon National Park, Arizona
These data provide a comprehensive survey of peak-stage indicators along the Colorado River corridor between river mile (RM) 0 and RM 87 (see Figure 1 in the associated USGS-SIR). In 2008, the locations of peak-stage indicators in three short reaches downstream from RM 87 were measured using a handheld GPS unit (see Appendix 1 in the associated USGS-SIR). Total-station measurements were made using an established network of survey control that references the 2011 realization of NAD83 (NAD83 (2011)) (Kaplinski and others, 2017). The measurements were projected into the State Plane Coordinate System of 1983, Arizona central zone (FIPS zone 0202). Vertical positions are provided in both NAD83 ellipsoid heights and in...
