ah, I get it, the "_CRS" attribute name is defined here: https://github.com/OSGeo/gdal/blob/f5076e774a8f43ec4ac7a6d8c234efe870dcc32a/frmts/zarr/zarr.h#L30 there is no "_TRANSFORM" attribute yet known to GDAL. Should it? Should it use rasterio transform ordering or...

I don't think GDAL understands the ways that Zarr is using to store CRS. Trying this I see ``` gdalinfo "ZARR:\"/vsizip//vsicurl/https://storage.googleapis.com/pl-amit-public/geozarr/planet-fusion.zarr.zip/planet-fusion.zarr\":/sr" Driver: Zarr/Zarr Files: /vsizip//vsicurl/https://storage.googleapis.com/pl-amit-public/geozarr/planet-fusion.zarr.zip/planet-fusion.zarr/sr/.zarray Size is 256, 256 Metadata:...

so I think the problems is that GDAL is looking for a valid key in "_CRS" of either url, wkt, or projjson, or grid_mapping - but in this example is...

gdal_footprint looks pretty good ```R library(terra) r

Certainly in PROJ, I'll have a try at some point, but don't have much capacity atm.

I didn't think that was what was being asked (right?), and I think Even misunderstood too. I was surprised to see that proj_trans_bounds returns just the 4 numbers. Confirmed with...

that only works in this particular case where the normal boundary aligns with the target one, not every projected region is the outline of -180,180,-90,90 and it won't work for...

also @mtennekes I can't see how to distinguish the edge of the world from NA, in your above example there are missing values literally outside the boundary which is convenient...

Can you point to specific products, and specific urls we can download or access via streaming (requiring auth is ok). This is very common, and GDAL has a lot of...

I'm still confident that this is a netcdf-variant issue. NetCDF is not modelled around raster-logic with an efficient and high-fidelity extent specification. Can you point to an actual L2W file?...
