VirtualiZarr is the way, don't necessarily need Icechunk. Check out Tom's in-dev open_virtual_mfdataset which is the xarray analog for open_mfdataset. I'm not clear yet on how specific format is for...

Oh, and multidim VRT is also perfectly capable, you still use the format library but this is close as an important bridge imo https://github.com/mdsumner/pymdim/blob/main/inst/examples/create_vrt_mdim.R (the VRT is beside the script...

I have never managed this with a tif, still confused about how to get that to work. I was using the latest dev of VirtualiZarr recently with netcdf: https://github.com/mdsumner/pawsey-aad/issues/5 Previously...

recording on the GeoZARR SWG meeting: https://fathom.video/share/XA84x7SU9-KwNo8gsN8muti1sQhw4y31 and full transcript was announced in this https://github.com/zarr-developers/geozarr-spec/issues/62#event-17115544959 (I couldn't attend sadly)

small feedback on the EOPF/ZARR geozarr format this description ``` "ZARR:\"/vsizip//vsicurl/https://eopf-public.s3.sbg.perf.cloud.ovh.net/eoproducts/S02MSIL1C_20230629T063559_0000_A064_T3A5.zarr.zip\":/quality/l1c_quicklook/r10m/tci" ``` gets the right georeferencing via `gdal raster info ` because here GuessGeoTransform() analyses the X,Y arrays and detects...

Some interesting tidbits: A take on CF/tif/Zarr harmonization https://github.com/zarr-developers/geozarr-spec/pull/67 Response to PR for EOPF-aligned CRS+transform (which, I consider a todo for me): https://github.com/EOPF-Sample-Service/GDAL-ZARR-EOPF/issues/20#issuecomment-2890251902

just adding a quick link to last year's results: https://gdal.org/en/stable/community/user_survey_2024.html

in an upcoming GDAL release (3.12, a while until that's available generally) you might get away with ``` vrt://METEO_DATA_202003120000.NC?transpose=lwrc:2,1 ``` as the input to `rast()` rather than the file name...

a potential enhancement tweak, group the output by "family" so there's some kind of indication of what those codes represent (for when the name is uninformative) (and put the UTM,...
