Collection Overview: USGS Logo This dataset contains laser scanner data from a helicopter platform designed by the Army Corps of Engineers' Cold Regions Research and Engineering Laboratory (CRREL), and the National Center for Airborne LiDAR Mapping (NCALM) at the University of Houston (Witter, et al. 2017). The platform was deployed on a Robinson R44 Raven II helicopter. The laser scanner operates at 1550 nm +/- 1 nm wavelength and is flown from 300 to 500 m above-ground at 30 - 60 kts with ground swath width of 300-500m and sampling of ~40 points/m2. These acquisition parameters yield vertical and horizontal accuracy of 3-5 cm & 6-10 cm, respectively. Standard processing techniques were used to remove laser returns from vegetation and enhance laser returns from the ground surface (Glennie, et al. 2014).
