PGC and Partners Win Award for EarthDEM Collaboration

We are honored to announce the EarthDEM team was recognized for the Best Academic / Government Collaboration in this year’s HPCWire Editors’ Choice Awards at the 2019 International Conference for High Performance Computing, Networking, Storage, and Analysis (SC19) in Denver, CO this week. The collaborative team includes PGC, National Geospatial-Intelligence Agency (NGA), NCSA Blue Waters, Byrd Polar and Climate Research Center, Ohio Supercomputer at the Ohio State University, the Arctic Geodata Cooperative, the National Science Foundation and the National Aeronautics and Space Administration.



ArcticDEM and REMA projects are constructed from hundreds of thousands of individual stereoscopic Digital Elevation Models (DEM) extracted from pairs of submeter resolution DigitalGlobe satellite imagery licensed by the National Geospatial-Intelligence Agency, including data from WorldView-1, WorldView-2, and WorldView-3 with a small percentage from GeoEye-1 sensor. The DEMs are generated by applying fully automated, stereo auto-correlation techniques to overlapping pairs of high-resolution optical satellite images using the open source Surface Extraction from TIN-based Searchspace Minimization (SETSM) software, developed by M.J. Noh and Ian Howat at the Ohio State University.  The images are processed to Digital Elevation Models using compute power on the Blue Waters supercomputer located at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign.
