GeoZarr Spec aims to provides a geospatial extension to the Zarr specification (v2). 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 is an early draft deveveloped in the frame of an European Space Agency (ESA) GSTP. Through the optional General Support Technology Programme (GSTP) ESA, Participating States and Industry work together to convert promising engineering concepts into a broad spectrum of useable products.
- Added visual portrayals and symbology (instead of quicklook)
- Specified default multiscale non-projection (pseudo 'Plate Carree')
- Refined multiscales metadata (crs and level attributes)
- Specified multiscales zoom level str
