Four new NCALM datasets available on OpenTopography
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.
Tasman South, New Zealand LINZ dataset now availble
Lidar survey of Dangermond Preserve, CA released on OpenTopography
Lidar data covering 129 km2 of the Nature Conservancy's Jack and Laura Dangermond Preserve at Point Conception, California has been released on OpenTopography. The Preserve protects over eight miles of near-pristine coastline and rare connected coastal habitat in Santa Barbara County. In 2018, Aeroptic, LLC, worked with The Nature Conservancy and ESRI to capture aerial lidar over the Preserve.

New NCALM dataset northwest of Salmon, Idaho available
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.
