  21. GEO Elevation has the suitable DEM for your needs

  22. What is WorldDEMTM • WorldDEMTMwill be part of GEOElevation Product Suite • First worldwide available DEM product at HRTE3 level (former DTED-3) • Homogeneous, seamless DEM covering entire Earth’s land mass (150 Mkm²) • Data acquisition within 3 years only (one source) • Acquired by TerraSAR-X and TanDEM-X flying in a very close and precise formation • WorldDEMTM will be available from 2014

  23. WorldDEMTM - Products Digital Surface Model (DSM) representing the surface of earth • DSM basic – no editing of objects • DSM hydro – editing of water bodies Digital Terrain Model (DTM) representing the elevation of bare earth Accuracy

  24. WorldDEMTM - USPs • Coverage A standardizedDEM for any spot on Earth at the same quality • Quality Allows you to close gaps in areas where no adequate DEM exists to date and extend to areas missing so far (cf. SRTM) with high accuracy • Accuracy Improve the performance of today’s globally operatingnavigation systems and applications • Availability Offers you easy and instant access to DSM basic due to an automatic order process and the global dataset being available, ensuring immediate delivery • The unique and unrivaled combination setting a • new standard • in global elevation modeling
