Summary
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 four rivers in Alaska from July 24-26, 2019 to support research related to remote sensing of river discharge. Data were acquired for the Matanuska, Chena, Salcha, and Tanana Rivers using a Riegl VQ-580 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 lidar point files in laz format for each river surveyed. Additionally, CRREL reports for each river surveyed are included [...]

Several imagery data sets were collected coincident with the lidar surveys but will be part of a separate data release.

Geospatial Repository and Data (GRiD) Management System is developed in a partnership between the US Army Corps of Engineers Cold Regions Research & Engineering Laboratory (CRREL) and the National Geospatial-Intelligence Agency's InnoVision directorate to efficiently warehouse and distribute both three-dimensional data, such as LiDAR data, as well as related and derived two-dimensional geospatial products, such as imagery and digital elevation models (DEMs).

Purpose
These LiDAR datasets provide information on river channel topography 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.
