Raster opentopoID: OTSDEM.112018.32641.1 Data Processing: https://portal.opentopography.org/raster?opentopoID=OTSDEM.112018.32641.1 ---------------------------------------------------------- Collection Overview: This dataset includes a suite of pre-seismic 2m resolution DEMs pre-dating the 2013 Mw7.7 Baluchistan earthquake. The DEMs were constructed using the open-source software package SETSM (https://mjremotesensing.wordpress.com/setsm/) from DigitalGlobe base imagery (©DigitalGlobe 2018). DEMs were mosaicked and vertically registered using the Ames StereoPipeline (https://ti.arc.nasa.gov/tech/asr/groups/intelligent-robotics/ngt/stereo/). The base imagery included 0.5m and 0.3m resolution panchromatic imagery from QuickBird, GEOEYE, WorldView1, WorldView2, and WorldView3 (©DigitalGlobe 2018). The dataset includes DEMs generated from in-track stereo imagery, as well as DEMs constructed from mixed pairs of non-in-track stereo images. The pre-event DEMs are all vertically registered to the 30 m Shuttle Radar Topography Mission (SRTM) DEM. The generation of this dataset was funded by NASA in cooperation with the U.S. Geological Survey. A complete description of the generation of this dataset and the images that were used to construct the DEMs can be found in the associated manuscript: Barnhart WD, Gold RD, Shea HN, Peterson KE, Briggs RW, Harbor DJ (2019) Vertical coseismic offsets derived from high-resolution stereogrammetric DSM differencing: The 2013 Baluchistan, Pakistan earthquake, JGR-Solid Earth DOI:10.1029/2018JB017107 The naming convention of individual DEMs is detailed in the metadata. Note: The source data for this project are the individual 2 meter DEMs that were constructed with the SETSM open-source software (described above). However, in order to utilize the OpenTopography webmap interface, these DEMs were mosaiced into a single seamless mosaic of pre-earthquake topography. Details on how this single mosaic was created are in the metadata. Users are cautioned that files created using the webmap interface will use the averaged, mosaic data. For certain applications, users may wish to utilize the source datasets by downloading the original DEMs via the "Source" directory under the "Bulk Download" section of the OpenTopography website.
