New SfM data over the Southern San Andreas Fault, CA
OpenTopography is pleased to release a new structure from motion (SfM) photogrammetry dataset that covers ~40 km of the Coachella section of the Southern San Andreas Fault. The data extend from north of Painted Canyon south to Bombay Beach, California, USA and include a well-georeferenced point cloud (8.4 x 109 points), 10 cm DSM, and 4 cm orthomosaic.
Three new NCALM datasets from California and Oregon available on OpenTopography
Three new lidar datasets collected by the National Center for Airborne Laser Mapping (NCALM) in California and Oregon are now available on OpenTopography. A repeat lidar dataset of Antelope Valley, CA covering approximately 24 km2 was collected by NCALM for Dr. William Dietrich at the University of California, Berkeley. The data were collected over Antelope Valley Ranch, ~60 km west of Yuba City, CA. Previous mapping of this area was completed in 2017, details of which can be found here.

New NCALM dataset in North Carolina
OpenTopography is pleased to announce the release of a new lidar dataset covering approximately 78 km2 near Hendersonville, North Carolina. This dataset was collected as part of an NCALM Seed grant for Dr. Corey Scheip at North Carolina State University to evaluate regional landslide area-volume scaling relationships after a large rainfall-triggered mass wasting event in western North Carolina. This project focused on how debris flows initiate, bulk, and deposit as a function of topographic variables.
