OpenTopography is happy to announce the release of seven new raster datasets. These datasets are derived from previously released point cloud data, and allow users to quickly and easily access high resolution digital elevation models. Six of these datasets were collected by the National Center for Airborne Laser Mapping (NCALM). NCALM is a NSF-funded center that supports the use of airborne laser mapping technology (a.k.a.
08/31/15 UPDATE: Due to concerns from the Principle Investigator of this project, NCALM has asked OpenTopography to take this dataset down. In accordance with this request, we’ve made the Mayapan dataset private until further notice.
OpenTopography is pleased to announce the release of two new datasets in eastern California: the Poleta Folds and Surprise Valley. The Poleta Folds airborne lidar data were collected by Chris Larson of the University of Alaska Fairbanks. This dataset is particularly exciting because the area is a beautiful example of classic structural geology, where many universities teach undergraduate mapping courses.
OpenTopography is pleased to announce the release of high resolution point cloud data collected after the 2014 South Napa Earthquake. The August 24, 2014, South Napa earthquake (M6.0) produced significant damage resulting from shaking, fault rupture, fault afterslip, and ground deformation.
