Baseline geomorphic map and land-surface parameters, derived from integrated topobathymetric elevation data, for the mainstem Klamath River corridor downstream of Iron Gate Dam, CA, 2018

This data release includes a file geodatabase with high-resolution geospatial products that illustrate the geomorphology and various land-surface parameters along a 313-kilometer segment of the mainstem Klamath River corridor downstream of Iron Gate Dam, CA. The geospatial products were derived from topobathymetric elevation data collected to document baseline topography and bathymetry before the removal of four hydro-electric dams. The elevation survey included aerial lidar, using an integrated topobathymetric sensor (with near-infrared and green wavelengths), and boat-based sonar measurements of water depths. Acquisition dates for the aerial topobathymetric lidar spanned 06/01/2018 to 06/14/2018. For the bathymetric sonar survey, [...]
