GeoZarr Spec aims to provide a geospatial extension to the Zarr specification. Zarr specifies a protocol and format used for storing Zarr arrays, while the present extension defines conventions and recommendations for storing multidimensional georeferenced grid of geospatial observations (including rasters).
This specification early drafts (<=v0.4) were created initially by Spacebel for the European Space Agency under the General Support Technology Programme.
Update 2023-01-20 - This spec is transitioning to community-based development in anticipation of submission as an OGC standard. It has been moved to the zarr-developers GitHub organization. Brianna Pagan (@briannapagan) has volunteered to coordinate the community development process.
Feedback from users and implementers will be solicited from the community and incorporated into future drafts.
Information about how to get involved in this process will be announced soon/
