TerraSim Awarded Phase II SBIR to Develop DEM Fusion Technology

January 25, 2004

Pittsburgh, PA - TerraSim, Inc. has been awarded a Phase II SBIR entitled "Automated Fusion of Digital Elevation Models" by the U.S. Army, to develop and commercialize technology allowing users of digital elevation models (DEMs) to merge multiple disparate sources of elevation data into consistent large area terrain models suitable for visualization, flood management planning, mission rehearsal and training, and large area mapping.

"We're quite pleased and excited to have been selected for a Phase II award," said Dr. Chris McGlone, Director of Mapping and Civil Applications. "We believe that DEM fusion represents an important and challenging topic, given the need to accommodate DEMs derived from a wide variety of sources. Airborne LIDAR, the Shuttle Radar Topography Mission (SRTM), scanned maps, and photogrammetrically derived contours and grids all represent increasingly popular elevation data sources, and there is a strong government and commercial need for tools that can merge arbitrary DEMs in a principled manner to generate DEM products with improved accuracy and precision."

"This award makes possible the development and commercialization of fast and robust DEM fusion tools, based on our Phase I efforts," remarked Dr. Jefferey A. Shufelt, principal investigator on the SBIR project. "We are pleased to continue our work with the U.S. Army Engineer and Research Development Center (ERDC-TEC) at Fort Belvoir, whose technical members have helped to focus our efforts."
