The new format for all Sentinel products: EOPF Zarr
.ical
2026-06-29 –, A13

The European Space Agency (ESA) is these days developing a new unified Zarr-based file format for Sentinel (1, 2, and 3) mission products under the Earth Observation Processing Framework (EOPF) initiative. EOPF Zarr enables scalable, cloud-native access to Earth Observation data and represents a significant shift in how EO products are distributed by ESA.

This talk introduces the EOPF Zarr format: its design, current status, and practical capabilities. We'll also cover the growing ecosystem of open-source tools being built around it, from plugins for GDAL, xarray, QGIS, R, and Julia, to interactive browser-based exploration of Sentinel imagery with no downloads or preprocessing required.

Whether you're new to cloud-based EO workflows or want to learn about the new format, this session will give you a clear picture of where EOPF stands today and how to get started with it.

Give indication of resources (video, web pages, papers, etc.) to read in advance, that will help get up to speed on advanced topics.:
