How To Access Data

Project Proposal (Restrained)

Go to the ESA User Services Portal
Register or log in to EO Sign In
After logging in, complete and submit the form with your proposed use of the data
The proposal will be evaluated by ESA, which normally takes between 4 and 6 weeks
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 following WorldDEM products can be requested:

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