Abstract
WorldDEM and GEO Elevation Suite - Global and Local

Digital Elevation Model (DEM) is the foundation for analyzing and modeling geo-processes on earth as well as input for generating any accurate geospatial products. Especially, in case of integration of multi-source data a precise DEM is key to a successful operational performance. Therefore, many applications require elevation information, e.g. satellite image orthorectification, multi-scale topographic and thematic mapping, infrastructure and network planning, aviation as well as defence and security related missions. Astrium Services has a long-time experience in elevation products started with a ready off-the-shelf 30m posting product since 2002 (known under the name of Reference3D). From 2014 on a new high-quality standardized elevation information will be on the market - the WorldDEM. The characteristics of the WorldDEM are the global coverage (pole to pole) allied with unique accuracy and quality. The 12m posting product will meet a vertical accuracy of 2m relative and better than 10m absolute and guarantee full homogeneity and seamlessness. These specifications exceed any other global satellite-based elevation model available today and will improve the performance of worldwide operating systems and cross-border mission planning. WorldDEM is intended to replace SRTM and is a quantum-leap in global elevation modeling. Since varying elevation models suit different type of applications, Astrium Services offers additionally a comprehensive elevation product suite consisting of up-to-date, precise products on different accuracy levels for any location on Earth. The elevation models are based on the company's unique access to multi-resolution and multi-sensor constellations including SPOT and Pléiades optical satellites as well as TerraSAR-X and TanDEM-X radar satellites.
