[gdal-dev] WMS supported SRS

[Michał Kowalczuk]

I found that there was a similar issue in 2021 without any specific answer:
https://www.mail-archive.com/gdal-dev@lists.osgeo.org/msg35549.html

I wonder if getting SUBDATASETS shouldn't return the result in a similar
way as it does for WMTS service,
where GDAL generates paths to all layer/tilematrix/tilematrixset
combination.
For example if layer is available in 3 SRS, GDAL produces 3 subdatasets, so
using only SUBDATASE_NAME property user has access to all map services
shared by WMTS server.
In my opinion, GDAL should use the same approach for WMS.

Does anyone object?
I will then submit a new feature request/bug report.

Best regards and have a nice day
