    Collection Overview: USGS logo University of Iowa logo

    This dataset includes a suite of pre-seismic, 2-meter resolution optical digital surface models (DSMs) pre-dating the July 2019 Ridgecrest earthquakes. The DSMs were constructed using DigitalGlobe base imagery (©DigitalGlobe 2019) and the open source SETSM software package . DSMs are vertically and horizontally registered to a separate pre-event optical DSM that was registered to ICESat-1 data. The base imagery includes 0.5m and 0.3m panchromatic in-track stereo imagery acquired from the WorldView-2 and WorldView-3 satellites. The generation of this data sets was funded in part by SCEC in cooperation with the U.S. Geological Survey.

    The naming description of individual DSMs is as follows:

    sensor_date _id1_id2_dem_2m-DEM.tif

    where sensor is the sensor from which imagery was acquired (WV02-WorldView2, WV03-WorldView3), date is the acquisition dates in format YYMMMDD (i.e., 13AUG11), and id1 and id2 are the image identifier numbers provided by DigitalGlobe.

    NOTE:This dataset covers a different spatial extent, and uses different base imagery than the similar dataset, 2019 Ridgecrest, CA Pre-Earthquake Digital Surface Model.
