DLR supports mountain expedition with 3D model

Germany: Scientists at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) scheduled testing the latest processes for converting satellite data into 3D models at K2 (8000 metres high), world’s second highest mountain peak. 
Stefan Dech, Director of the German Remote Sensing Data Center (Deutsches Fernerkundungsdatenzentrum; DFD) at DLR said,  “The flanks of K2 are very steep, and the high contrast between ice, snow and dark rock complicates the process of using optical data from space to create a highly-accurate 3D model.”
In the autumn of 2010, DLR ordered data from the US WorldView-2 satellite and made a number of special requests to the operating company, DigitalGlobe. From the collected data, the DLR researchers created views of K2 with a resolution of less than one metre. This is the first time that images of this quality have been published. 
The K2 elevation model was generated using the latest stereo-optical evaluation processes at the DLR Remote Sensing Technology Institute (Institut für Methodik der Fernerkundung; IMF). The perspective images and animations were then produced at DFD. “We need elevation models for almost every geoscientific investigation. For this reason, we are researching methods to create elevation models from both optical and radar data,” said Richard Bamler, Director of the IMF. The DLR researchers were able to generate special perspectives of the 8000-metre mountain between Pakistan and China, to supply the mountaineers with the most precise information possible for their ascent.
