[gdal-dev] Issue with the STACIT usage examples

[Rahkonen Jukka]

Hi,

In case of STACIT, I can’t discover how to use the vrt:// connection string https://gdal.org/en/latest/drivers/raster/vrt.html#vrt-connection-string with subdataset name (or even without). Can you?

Start with
 gdalinfo  "STACIT:\https://planetarycomputer.microsoft.com/api/stac/v1/search?collections=naip^&bbox=-100,40,-99,41^&datetime=2019-01-01T00:00:00Z%2F..\
and try to show a vrt:// string for
  SUBDATASET_1_NAME=STACIT:https://planetarycomputer.microsoft.com/api/stac/v1/search?collections=naip&bbox=-100,40,-99,41&datetime=2019-01-01T00:00:00Z%2F..:asset=image

Understood, and good reason to start using the new gdalinfo convenience option "-sd" for selecting sub-datasets by their index.

Do beware that index isn't necessarily reliable (good old netcdf), it can change through an ostensibly consistent dataset while name does remain robust.

vrt:// has sd_name for this purpose, and to avoid driver declaration with full subdataset syntax.

I may have considered sd_name for gdalinfo ?? probably a good idea. And maybe something to put on the 4.0 break list 🙏

Cheers, Mike

However, the subdataset names on the list are not accepted as-is without small edits.
Does not work:
gdalinfo STACIT:"https://paituli.csc.fi/geoserver/ogc/stac/v1/search?collections=corine_land_cover_at_geocubes"<https://paituli.csc.fi/geoserver/ogc/stac/v1/search?collections=corine_land_cover_at_geocubes>:asset=1000m

That's "expected". Subdataset names are designed to be used verbatim by GDALOpen(). The STACIT driver isn't aware it has been invoked from a shell and which quoting rules would apply.
