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 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.
OpenTopography is pleased to announce that we're now offering access to USGS 3D Elevation Program (3DEP) Standard Digital Elevation Models (DEMs) through our easy to use web-based interface with associated processing and visualization tools.
OpenTopography is pleased to announce the release of a new lidar dataset covering 166 square kilometers of Queenstown and Arrowtown on the South Island of New Zealand. The dataset, "Queenstown, Otago, New Zealand 2021" has an average point spacing of 7.8 pts/m2, and was funded by the Queenstown Lakes District Council , with data management by Toitū Te Whenua Land Information New Zealand (LINZ).
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.
