Announcement of Opportunity for the final TanDEM-X Digital Elevation Model

Aug 25, 2016

Today, the announcement of opportunity (AO) for the final TanDEM-X Digital Elevation Model (DEM) has been launched!

This AO is related to the provision of the digital elevation products with 12 m and 30 m independent pixel spacing generated by the TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) mission.

TanDEM-X was launched in 2010 and has been operating together with its twin TerraSAR-X as a bistatic SAR interferometer since the beginning of 2011. The first four years were dedicated to global acquisitions using baseline geometries optimized for the required DEM performance. During this time, the Earth was covered at least twice. In difficult areas like mountainous regions or deserts, up to six coverages were performed utilizing different incidence angles and viewing geometries. The processing and mosaicking of the TanDEM-X DEM with the requested specification has been just completed and is now available for the science community.

The data requested through this announcement of opportunity is only available for scientific purposes.

Detailed information about the TanDEM-X AO and the provided products are included in a technical note available on the TanDEM-X science server (see web link below).

Your proposal must be submitted via a web based interface provided on the home page of our TanDEM-X Science Service System:

The data for this call will be delivered free of charge for all approved proposals. The due date for proposal submission is December 1st, 2016.

If you have any questions concerning this AO, please contact the TanDEM-X Science Coordination team at Further information will be also available during the TerraSAR-X/TanDEM-X science meeting in October, 17-20, 2016 in Oberpfaffenhofen.

Further TanDEM-X DEM product variants will be announced in a separate dedicated AO call.
