How To Access Data

Project Proposal (Restrained)

  1. Go to the ESA User Services Portal
  2. Register or log in to EO Sign In
  3. After logging in, complete and submit the form with your proposed use of the data
  4. The proposal will be evaluated by ESA, which normally takes between 4 and 6 weeks
  5. Upon successful evaluation, you will receive a confirmation email, which describes the amount of data to be provided, and details of how to order the 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 to order on demand upon submission of a Project Proposal subject to evaluation and acceptance by ESA and the data owner.

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.

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.

All details about data provision and availability, data access conditions, usage restrictions and the quota assignment procedure are described in the Terms of Applicability document available in the Resources section.

If you need help with the proposal form, consult this guide on how to access data requiring a project proposal

The following WorldDEM products can be requested:

ProductsDescription
WorldDEMcoreWorldDEMcore is output of interferometric processing of StripMap data pairs without any post-processing
WorldDEMTMWorldDEMTM is produced based on WorldDEMcore, representing the surface of the Earth (including buildings, infrastructure and vegetation). Hydrological consistency is ensured
WorldDEM DTMIn additional editing steps, WorldDEMTMis transformed into a Digital Terrain Model (DTM) representing bare Earth elevation
WorldDEM BundleIncludes 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
