Salut à tous,
Un intéressant dernier post dans le forum Pangeo sur EOPF :

The definition of the specifications initiative began in 2024 and will continue until 2026, when ESA is expected to start operationally producing the new Zarr from the ground segment.
A key point confirmed by all ESA technical officers is that there will be no Zipped Zarr in the final implementation . The Zipped Zarr format is only a temporary workaround for managing the enormous number of files generated by the combination of the EOPF data model, partitioning, and Zarr structure for a single data product. This is where contributions like sharding will be welcome.
ESA also aims to implement a Discrete Global Grid System (DGGS) for data mapping to reduce current data duplication, which can be as high as 30% due to Sentinel-2’s current UTM gridding.
The key takeaway is that ESA’s current focus is on promoting community engagement and encouraging user adoption, which is a welcomed effort.
A nous de nous investir ?
