The number of repeat DEMs, the median absolute deviation, and the time range of DEM acquisitions at each mosaic pixel are provided to identify potential areas of poor quality data and highlight rapidly changing features. The mosaic provides the median value of elevations from repeat strip DEMs, with filtering applied to remove outliers. MethodologyĭEM mosaic tiles are formed into 100km x 100 km tiles in the local UTM projection. Detailed mosaic tiling scheme information can be found in the EarthDEM documentation. There is a different mosaic tiling scheme for each UTM zone, but each zone overlaps adjacent zones. #Dem earth c4d download download#Download the EarthDEM v1 2m tile DEM index shapefile to see the mosaic extents.Ģm mosaic tiles are in the local UTM projection. #Dem earth c4d download registration#No ground control or altimetry registration has been applied to the mosaics. Elevation units are meters and are relative to the WGS84 ellipsoid. A reduced-resolution, 10-meter resampled version is also available. In addition to the individual time-stamped strips, EarthDEM includes a mosaic in 50 km x 50 km mosaic tiles at 2-meter resolution. National Science Foundation funding supported the significant compute resources and development of the production pipeline and algorithms through earlier projects including ArcticDEM and REMA. Without Blue Waters resources, DEM extraction at this scale would not be possible. The Blue Waters sustained-petascale system is one of the most powerful supercomputers in the world. Noh and Ian Howat at the Ohio State University with support from the Ohio Supercomputer Center, stereoscopic images were processed to Digital Elevation Models using compute resources provided by the Blue Waters supercomputer located at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign. Using the open-source Surface Extraction from TIN-based Search-space Minimization (SETSM) software, developed by M.J. If you continué to usé this site wé will assume thát you are háppy with it.EarthDEM products are generated by applying fully automated, stereo auto-correlation techniques to overlapping pairs of high-resolution optical satellite images.
