The Earth in 3D - first images published

Reply Sat 26 Jun, 2010 06:57 am
The German radar satellite TanDEM-X was launched on June 21 by the German Aerospace Center (DLR) to join an identical satellite, TerraSAR-X, which was launched in 2007. The two satellites will fly in formation to create the most detailed 3D pictures of Earth ever obtained.

Now, the first images are published - 3 days and 14 hours after the satellite was launched - in an extremely high quality, better than any other previous satellite images, it is said.

@Walter Hinteler,
Flying in formation, TanDEM-X and TerraSAR-X will generate a precise global elevation model.

For vast swathes of Earth, at present only rough, inconsistent, or incomplete elevation models are available from different data sources and measurement techniques. TanDEM-X will close these gaps and will provide precise elevation data in a 12-metre grid. This elevation model shows different accuracies: 1 kilometre, 90 metres, 30 metres and 12 metres (TanDEM-X).
