OpenTopography is pleased to announce the release of seven new lidar datasets collected by the National Center for Airborne Laser Mapping (NCALM) in areas of Arizona, California, Mississippi, Oregon, and Utah. NCALM is a 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. Six of the datasets were collected in Fall 2013 under NCALM's graduate student seed proposal program that awards ten projects per year to graduate student PIs who need lidar data for their research. Each collection is typically limited to no more than 40 square kilometers. The release of these data via OpenTopography is the product of a memorandum of understanding (MOU) between OpenTopography and NCALM to make OT the primary distribution pathway for NCALM data.
