OpenTopography is pleased to announce the release of two digital surface models (DSMs) that are mosaics of two meter resolution stereogrammetric DSMs constructed using DigitalGlobe base imagery (©DigitalGlobe 2019) acquired before and after the July 2019 Ridgecrest, California earthquake sequence. These datasets cover over 8,000 km 2 of the region surrounding the recent earthquakes, and provide a unique opportunity for research of this event. The datasets were produced by William Barnhart, University of Iowa.
