Four new NCALM datasets available on OpenTopography

Jun 6, 2022

Four new lidar datasets collected by the National Center for Airborne Laser Mapping (NCALM) are now available on OpenTopography. These include a dataset covering 73 km2 of the Marble, Middle and East Forks of the Kaweah River in the Sierra Nevada mountains in California. This dataset was collected in 2021 as part of an NCALM Seed Grant for Sophie Rothman at the University of Nevada, Reno to assess how self-generation and retreat of bedrock steps and waterfalls can alter river profiles.

New NCALM dataset northwest of Salmon, Idaho available

Mar 14, 2022

A new lidar dataset covering 42 km2 northwest of Salmon, Idaho is now available on OpenTopography. This lidar dataset was collected by the National Center for Airborne Laser Mapping (NCALM) for Brian Yanites at Indiana University, Bloomington in order to quantify the impact of a drainage diversion in the late 19th century on landscape processes. The lidar data will be used to map the channel morphology, landslides, and tension cracks that continue to propagate across the landscape to this day within the Dump Creek basin.
