This is a general question relating to openEO Platform:
- Short description:
- Specific request/idea/comment:
I’m looking for advice on how to open and work with Daymet Zarr collections(https://planetarycomputer.microsoft.com/api/stac/v1/collections/daymet-annual-pr) . Is there a recommended approach or example for handling Zarr data through openeo-python-clinet(GitHub - Open-EO/openeo-python-client: Python client API for OpenEO), or would it be simpler to use Xarray directly in this case?
If any of you have successfully interacted with Zarr datasets (for instance, the Daymet dataset from the Planetary Computer) through openEO, I’d appreciate any guidance or links to relevant examples. Thanks in advance for your help!
Hi,
we are still in the process of extending the Terrascope backend with Zarr support. When that feature is complete, this should work.
@valentina.hutter perhaps the XArray backend can do this already?
@michele.claus has been working on load_stac, so I need to forward this question - the PR is still work in progress, I think.
Hi @parthivpradeep. I’ve just had a look at the Daymet Annual Puerto Rico
STAC Collection. It is not yet supported, since it has a particular structure which I never encountered before: STAC Collection with assets
containing the Zarr files and without any items
. I did implemented the support of Zarr in a STAC Collection like the ERA5 provided by Microsoft, but the structure is different, with many Zarr files, one each month. Since there is no standardized way to create STAC Collections containing Zarr, it’s not easy to support all the possibilities.
