Bathymetric lidar data from the Colorado River, near Lees Ferry, Arizona, September 23, 2019
Description
The U.S. Geological Survey contracted with Juniper Unmanned to conduct field tests of the ASTRALiTe bathymetric lidar system on the Colorado River near Lees Ferry, Arizona, on September 23, 2019. The objective of this project was to assess the potential to map river bathymetry (i.e., channel bed topography) using lidar data. The ASTRALiTe lidar instrument was mounted on a cataraft owned and operated by USGS Grand Canyon Monitoring and Research Center. This data release includes data delivered to the USGS by ASTRALite on November 1, 2019. The data are in *txt format and include bare earth (i.e., river bed) and water surface returns and have not been filtered or modified in any other way.
