[gdal-dev] Proposal for GDAL Driver: EOPF Zarr (Earth Observation Product Format)

[Even Rouault]

Hi Yuvraj,


A few questions:

- what is the maturity of the EOPF enhancements ?

- where are they described ? (i.e. the format specification)

- why not enhancing the existing Zarr driver ?

- from what I can currently see in 
https://github.com/EOPF-Sample-Service/GDAL-ZARR-EOPF/tree/main/src, 
this seems more to be a skeleton of a driver that something production ready

> Hello GDAL Community,
> We’re developing a GDAL driver for the Earth Observation Product 
> Format (EOPF), a cloud-optimized Zarr-based format tailored for 
> large-scale EO data.
> This driver aims to enable seamless access to EOPF datasets and their 
> metadata through GDAL, supporting features like chunked I/O, and  
> compatibility with STAC metadata.
> Key features:
> - Support for Zarr V2/V3 structures with EOPF-specific enhancements.
> - Integration with cloud storage (S3, GCS, etc.).
> - Alignment with ESA/Copernicus data standards.
> We’d appreciate your feedback on integration requirements and best 
> practices. The code is available at EOPF-Sample-Service/GDAL-ZARR-EOPF 
> <https://github.com/EOPF-Sample-Service/GDAL-ZARR-EOPF>, and we plan 
> to submit a PR soon.
