12-meter WorldDEM Samples are Ready for Download

For the past two and a half years, Astrium GEO’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.

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

The key specifications of Astrium’s WorldDEM are as follows:

  • 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:

      Hi Christain – thanks for the comment. This product will not be ready for delivery for at least several months. Can you wait that long for this project?

      Hi Mesued – thanks for the comment. This DEM is not ready for sales yet. It will be in the coming months. When it is ready to purchase, we will surely have an announcement in our newsletter.

      Hi Victoria – thanks for the comment. The WorldDEM is not ready for the market yet. When it is, we will have an article in our newsletter about it. Stay tuned!

  2. Hi. I am a final year student at Jomo Kenyatta University of Agriculture and Technology, Kenya, taking BSc. Geomatic Engineering and GIS. I am to do my final year project titled “CREATION AND OPTIMIZATION OF STORM WATER AND SEWERAGE NETWORK JUJA USING GIS”. I need a 12m resolution DEM for Juja area (Kenya) as one of my data sets. Would you kindly provide it? You will have played a great role in my education. Thank you
