New Release: Digital Surface Models of Ridgecrest, CA: Pre and Post July 2019 Earthquakes

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.
