A view of K2 from the west. This rare image was photographed by the German extreme moutaineer Ralf Dujmovits from the slopes of Praqpa Ri. Next to it on the right is a view of K2 computed from satellite data.
In autumn 2010 K2 was measured from three different angles by the US satellite "Worldview-2". From the differences in the viewing angles of these images, EOC scientists calculated a high-resolution elevation model with a methodology specifically developed for the purpose at DLR. With this virtual image, K2 can now be visualized from any angle, also, of course, from the direction of Praqpa Ri. A comparison shows how faithfully the virtual portrayal reproduces the original. The methodology has since been tested also on other “world-class mountains”.
