Hint: use EPSG:4326 for the SRS of the .gti.fgb, because this is the SRS
of the tiles. The GTI driver isn't smart enough to figure out that
OGC:CRS84 ~= EPSG:4326, and thus a rather dummy on-the-fly warping is done.

Hi Jukka,
this is a unfortunate move. You may have to create a custom package,
possibly inspired from src.rpm from recent Fedora
(https://src.fedoraproject.org/rpms/gdal). I see Markus Neteler did one
for GDAL 3.0.4 for RHEL 7 in
https://copr.fedorainfracloud.org/coprs/neteler/GDAL/
Or I as
Hi,
The newest GDAL in the official RHEL repo is 3.4.3, released 2022-04-22. There
used to be GDAL 3.7 available from the PostgreSQL repo
https://yum.postgresql.org/repopackages/ and we have been using that, but the
version was removed recently. Some other user was unhappy as well and created a
as you could also attach the XRES, YRES, BANDCOUNT, etc. metadata
items that would help the GTI driver avoid probing one of the tiles.
PS: OGRLayer::SetMetadataItem(key, value) only works on FlatGeoBuf and
GPKG drivers with latest master as well

ah thanks, all very helpful - no it's not done with master (for various
reasons), I'll follow up with details if relevant, mostly I was just
excited to get a useable workflow for the entire process.

Michael,
You need to attach the CRS at layer creation time with:
layer = ds.CreateLayer(layer_name, geom_type=ogr.wkbPolygon, srs=sr)
Setting it with featureDefn.GetGeomFieldDefn(0).SetSpatialRef() is
illegal. Now that

awesome, thanks Even I'm having fun with this one.
For anyone interested I created Python to parse the OpenTopography COP90
VRT (I have to wget it locally as I don't know how to hit the URL for the
xml yet).
