WorldDEM Coming in 2014: Most Accurate Yet Global DEM

Mon, 2012/10/22 - 14:56 — Satri

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 "
