Hi James,<br>
<br>
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.<br>
I create such xml file based on information from here:

Also I test this xml in QGIS - works fine.<br>

<pre wrap="">>From <a class="moz-txt-link-freetext" href="http://www.gdal.org/frmt_wms.html">http://www.gdal.org/frmt_wms.html</a> I see you can access an ArcGIS REST API like:
gdalinfo <a class="moz-txt-link-rfc2396E" href="http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true">"http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true"</a>
and
gdal_translate <a class="moz-txt-link-rfc2396E" href="http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json">"http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json"</a> wms.xml -of WMS
These above examples work for me.
When I try on a BGS service it fails as below:
...:\>gdalinfo <a class="moz-txt-link-rfc2396E" href="https://map.bgs.ac.uk/arcgis/rest/services/UKSO/UKSO_BGS/MapServer?f=json&pretty=true">"https://map.bgs.ac.uk/arcgis/rest/services/UKSO/UKSO_BGS/MapServer?f=json&pretty=true"</a>

GDALOpen failed - 0
Is the reason that HTTPS is not supported here at all, or if not what might be wrong with the service/request/ configuration?
Thanks
