Value-Adding Products & Algorithms for Land Surfaces
Theia at a glance
Theia is pursuing four main objectives :
- Promoting and facilitating the use of space data, for science and public
actors, in terms of imagery, added-value products as well as in-situ data; - Developing added -value products and services for the science communities
and national public actors; - Developing networks of competences
- Supporting French realizations at European and international level.
Observing Earth
Theia is now one of the active members of the Earth System Research Infrastructure, Data Terra.
Along, three other French Earth Observation consortia:
- Aeris – the French thematic consortium on Atmosphere
- ForM@Ter – the French thematic consortium on Solid Earth
- Odatis – the French Thematic consortium on Ocean spatial observation.
- and Dinamis, the French pooled system for access to satellite imagery.
