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.
