Terrestrial Light Detection and Ranging Topographic Data at a Recreation Site Upstream from Nimrod Lake, Arkansas, March 2020

Topographic data were collected at a recreation site on the Fourche La Fave River, about 5 miles upstream from Nimrod, Arkansas, on March 4, 2020, using terrestrial light detection and ranging (T-lidar), Global Navigation Satellite System (GNSS), and conventional surveying techniques (Rydlund and Densmore, 2012).
These data are high-resolution topography in laser scan format, collected using a tripod mounted T-lidar at multiple scan setups. Data collection software integrated and stored the range and angular measurements from the T-lidar equipment. Computer software was used to process the raw data, align the various scans in reference to one another, classify the data, and extract the topography data in a useable format. The data were saved with RGB color and classification in LAS format (14.2 million points).
