Hi James,
As the server didn't provide information about levels, some help needed
to calculate this values. Also the all layers switched off, so we need
to tell which layers should be shown.
I create such xml file based on information from here:
https://map.bgs.ac.uk/arcgis/rest/services/UKSO/UKSO_BGS/MapServer?f=json&pretty=true
<GDAL_WMS>
<Service name="AGS">

Also I test this xml in QGIS - works fine.

>Fromhttp://www.gdal.org/frmt_wms.html I see you can access an ArcGIS REST
API like:
gdalinfo"http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true";
and
gdal_translate"http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json";
wms.xml -of WMS
These above examples work for me.
When I try on a BGS service it fails as below:

gdalinfo failed - unable to open

Is the reason that HTTPS is not supported here at all, or if not what might be
wrong with the service/request/ configuration?
Thanks
