New NCALM dataset along coast of Lake Michigan, Wisconsin

Oct 11, 2021

A new lidar dataset covering 84 km2 along the coast of Lake Michigan east of Milwaukee, Wisconsin is now available on OpenTopography. This lidar dataset was collected as part of a National Center for Airborne Laser Mapping (NCALM) seed grant for Collin Roland at the University of Wisconsin and includes bathymetry. This study used airborne lidar to assess Lake Michigan coastal erosion by measuring the geomorphic response to extremely high lake levels.

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.
