NEW PRODUCTION AND DISTRIBUTION MEANS FOR THE CNES THEIA CDS
As part of THEIA activities at CNES, the THEIA CDS team at CNES is pleased to announce the launch of the new Production and Distribution Centers.
HESPERIDES, a new and enhanced production center
The new Production Center is called HESPERIDES : it has replaced the former MUSCATE Production Center, which had been in operation since 2017, as of December 12, 2024. This new center offers improved processing performance, enabling production over larger geographical areas (with an initial goal of doubling the processed surface area compared to the previous system).

The HESPERIDES Production Center consists of several production units:
- A first unit dedicated to real-time processing for all processing chains.
- A second unit dedicated to reprocessing archived data.
- An “Expert” unit, coming soon, to implement innovative, one-off processing tasks (scaling up, fine-tuning processing chains, producing non-systematic geographic areas, investigations, validations, etc.).
The HESPERIDES Production Center is managed, operated, and funded by CNES.
GEODES, the new CNES distribution platform
Product distribution is also evolving. THEIA products, which were previously available on the Postel, Take5, and Theia.cnes.fr websites, are now accessible via the GEODES portal (https://geodes-portal.cnes.fr), which has been online since November 7, 2024.
GEODES provides centralized access to data and products from CNES Earth Observation missions and Sentinel-1 and Sentinel-2 missions from the Copernicus program.
Additionally, GEODES offers access to a subset of thematic products developed under the THEIA program and produced by the CNES THEIA Production Center, including :
- Surface reflectance products and monthly syntheses from Sentinel-2 (Levels 2A and 3A).
- Surface reflectance products and monthly syntheses from Venus (Levels 2A and 3A).
- Land cover products (OSO).
- Biophysical variables (LAI, FAPAR, FCover) GEO2-AVHRR.
Feel free to explore the features and products available on this new platform !

GEODES Platform available online : Illustration of the user interface with an example of available products: Sentinel-2 products.

For hydrological products, there are no changes ; they remain available on Hydroweb.Next.
Please note that the historical sites Postel, Take5, and Theia.cnes.fr will be permanently shut down at the end of January 2025 due to obsolescence.
