Sent to you by Hugo Martins via Google Reader: WorldDEM Coming in 2014: Most Accurate Yet Global DEM via Slashgeo.org by Satri on 10/22/12
We mentioned TanDEM-X before, TerraSAR-X too, and global DEMs like SRTM-DEM and ASTER GDEM, and there's going to be a new major global DEM available in 2014, WorldDEM. From the DM article: "The TanDEM-X mission is to generate a global digital elevation model - WorldDEM - of unprecedented quality, accuracy and coverage. This DEM is intended to be the replacement dataset for SRTM and will be available in 2014 for the Earth’s entire land surface - pole to pole. The accuracy of the WorldDEM will surpass that of any satellite-based elevation model available today and will have the following unique features: - Vertical accuracy of 2m (relative) and 10m (absolute) - 12m x 12m raster - Global homogeneity - Highly consistent dataset as a result of an initial global data collection window of 2.5 years and the opportunity to continue to collect locally beyond the initial collection period - No need for ground control information due to the high geometric precision of German sensors " Google Plus One Things you can do from here: - Subscribe to Slashgeo.org using Google Reader - Get started using Google Reader to easily keep up with all your favorite sites
