Implement support for ZARR file subsetting and downloading #34
Comments
Hi @pepijn-devries, Is your comment about ZARR files related to my inquiry? Can you expand more on what you are talking about here? Is this a way to download layers from BGC_001_028 product? Thanks, |
Hi @dancrear, The Copernicus Marine Service providing the ZARR files is not the same as the STAC service, so in that respect it is not related to your earlier inquiry (issue #36 for the record). Copernicus Marine Services provide a subsetting services that delivers ZARR files, which is related to the service I have implemented as The issue reported here: #33 is about the currently implemented subsetting feature ( Hopefully, it's a bit more clear now? I wanted to add some links to some documentation about the services and their API, but I could not find any. Which is why I have to rely on reverse engineering on my part (which is not most efficient, I know). Cheers, Pepijn |
Hi,
I really appreciate the response and understand the situation now.
Hopefully you hear back from Copernicus Marine soon. Thanks again!

Hi @dancrear <https://github.com/dancrear>,
The Copernicus Marine Service providing the ZARR files is not the same as
the STAC service, so in that respect it is not related to your earlier
inquiry (issue #36
<#36> for the
record). Copernicus Marine Services provide a subsetting services that
delivers ZARR files, which is related to the service I have implemented as
cms_download_subset() (which delivers netcdf files instead). The first
produces smaller files and is therefore faster. But because of issue
r-spatial/stars#564 <r-spatial/stars#564>, I
will wait with implementing this feature until that issue has been resolved.
The issue reported here: #33
<#33> is about
the currently implemented subsetting feature (cms_download_subset()),
which apparently does not work for that particular product. As it is
unclear what is going wrong there, I will contact the people at Copernicus
Marine about that. As an alternative I wish to implement the
'ZARR-feature', which has the problem stated above.
Hopefully, it's a bit more clear now? I wanted to add some links to some
documentation about the services and their API, but I could not find any.
Which is why I have to rely on reverse engineering on my part (which is not
most efficient, I know).
Cheers,
Pepijn

Hi @dancrear , Note that I'm touch now with the Copernicus Service desk, it may take a while to sort things out. I'll keep you posted here... Cheers, Pepijn |
It should be possible to load the ZARR files in R. let's implement this feature...
