TerraSAR-X/TanDEM-X full archive and tasking

How to Access Data

The collection is open for research and application development, prototype and test projects to users located in the territory of ESA Member States (including Canada), in the European Commission Member States and in Africa.

Data are available for on demand ordering upon submission of a Project Proposal subject to evaluation and acceptance by ESA and data owner.

The process takes up to two weeks and there are no deadlines for submitting a proposal.

For further information about the EO Sign In Service you can visit TellUs.

Should you need support please contact EOHelp

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be allowed to each project. Availability and restrictions to the use of the data are described in the ESA Third Party Missions (TPM) T&C and in the Terms of Applicability document

The following WorldDEM products can be requested:

Products Description
WorldDEMcore WorldDEMcore is output of interferometric processing of StripMap data pairs without any post-processing
WorldDEMTM WorldDEMTM is produced based on WorldDEMcore, representing the surface of the Earth (including buildings, infrastructure and vegetation). Hydrological consistency is ensured
WorldDEM DTM In additional editing steps, WorldDEMTMis transformed into a Digital Terrain Model (DTM) representing bare Earth elevation
WorldDEM Bundle Includes WorldDEMTM, WorldDEM DTM, and Quality Layers


The main specifications of the WorldDEM products are:

  • Horizontal Coordinate Reference System: World Geodetic System 1984 (WGS84-G1150)
  • Vertical Coordinate Reference System: Earth Gravitational Model 2008 (EGM2008)
  • Absolute Horizontal Accuracy: <6 m
  • Vertical Accuracy: 2 m Relative, 4 m Absolute
  • Quality Layers (including water body mask) can be requested as an option with the WorldDEM and WorldDEM DTM
  • Auxiliary Layers are delivered together with the WorldDEMcore product

The products are available as part of the Airbus provision from TerraSAR-X and Tandem-X missions with worldwide coverage: the TerraSAR-X/TanDEM-X Catalogue can be accessed to discover and check the basic product data readiness; using the WorldDEM database viewers.
