12-meter WorldDEM Samples are Ready for Download

For the past two and a half years, Airbus Defense and Space’s twin high-resolution radar satellites, TerraSar-X and TanDEM-X, have imaged the entire land surface of our planet multiple times to create the first ever 12-meter (m) global elevation model, the WorldDEM. Expected to be ready for commercial sales by mid-2014, Apollo Mapping is happy to announce that 12-m WorldDEM samples are ready for download over three locations.

The key specifications of Airbus Defense and Space’s WorldDEM are as follows:

A comparison of two DSMs: first a 30-meter (i.e. free ASTER GDEM resolution) layer; and second a 12-meter WorldDEM layer.

• Resolution: 12-m
• Vertical Accuracy: 2-m (relative), 10-m (absolute)
• Format: digital surface models (DSM) & digital terrain models (DTM)
• Vintage: all data collected within 2.5-years
• Source: synthetic aperture radar (SAR) satellites TerraSAR-X & TanDEM-X

You can download the three 12-m WorldDEM samples here:

• Buraydah, Saudi Arabia–desert with agriculture present; 576 m to 737 m
• Mjosa Lake, Norway–hilly terrain with large water bodies; 100 m to 840 m
• Wagga Wagga, Australia–forest and urban with many water bodies; 137 m to 922 m
