The German satellite radar twins - TanDEM-X and TerraSAR-X - are a year through their quest to make the most precise, seamless map of varying height on Earth.
They've now acquired data across the entire globe at least once. However, some tricky sampling areas, such as tall mountains and thick forests, will require several passes and so we don't expect to see a fully finished product before 2014.
The Digital Elevation Model, or DEM, has become one of those must-have technical tools.

Nice Improvement When It's Done
That will be a significant improvement over the SRTM DEM currently available.

WOW! Thanks for posting
It wil be fascinating to see how this data eventually trickles down to personal devices.
