What is the Data User Element?
The Data User Element, also called DUE, is an element of the Earth Observation Envelope Programme (EOEP), an optional programme of the European Space Agency, currently subscribed by all ESA Member States. It follows the 5 year Data User Programme (DUP) that lasted from 1997 to 2002. The DUE, like its predecesor DUP, tries to promote the development of Earth Observation (EO) demonstration services that fully respond to the needs of end-user communities.

Why should a user organisation participate to a DUE project?
The European Space Agency provides all user organisations that participate to a DUE project with free access to the project results and to the geo-information products / system developed during the course of the project. DUE projects are also a unique opportunity for user organisations to get acquainted with new space technologies that can provide substantial benefit to their operational duties.

What are the conditions for user participation to a DUE project?
In order to be eligible for participation in a DUE project, user organisations are requested to commit the provision of resources in support to the project execution (e.g. manpower, access to data and infrastructure, support to product definition and qualification, etc.). More information is provided in the "User Partnership" area.
