Kinzel, P.J., Legleiter, C.J., LeWinter, A.L., Gadomski, P.J., and Filiano, D.L., 2019, Topographic LiDAR surveys of rivers in Alaska, August 27-September 1, 2018, U.S. Geological Survey data release,


The U.S. Geological Survey in collaboration with the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL) collected topographic LiDAR surveys of six rivers in Alaska from August 27-September 1, 2018 to support research related to remote sensing of river discharge. Data were acquired for the Knik, Matanuska, Chena, Salcha, Tanana and Snow Rivers using a Riegl VQ-480 LiDAR. The LiDAR was installed on a Robinson R44 Raven helicopter in a HeliPod that was designed and operated by CRREL. The LiDAR data included as part of this release include: a bare earth digital elevation model (DEM) in GeoTiff format, and compressed binary LAS files (LAZ) for each river surveyed.

These LiDAR datasets provide information on river channel topography and the intensity of LiDAR returns for the rivers of interest. The goal of this project was to assess the feasibility and accuracy of a helicopter mounted LiDAR for measuring river channel characteristics. These data were acquired to develop a methodology for measuring river discharge using remotely sensed data.
