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.

NCALM is an NSF-funded center that supports the use of airborne laser mapping technology (a.k.a. lidar) in the scientific community and is jointly operated by the Department of Civil & Environmental Engineering, Cullen College of Engineering, University of Houston and the Department of Earth and Planetary Science, University of California, Berkeley. OpenTopography is the primary distributor of NCALM data.
