terraserver WMS getcapabilities not understood

[neteler@…]

Hi,

when accessing ​http://terraserver.microsoft.com/ogccapabilities.ashx

QGIS is segfaulting...

Best, Markus

Are you using trunk or 0.8 branch?

[anonymous]

The HEAD version, so trunk, updated right now. Ah, it no longer segfaults but returns to the menu. Very good.

Changing the topic to "terraserver WMS getcapabilities not understood".

After clicking "connect", I get

Could not understand the response.  The wms provider said:

The file returned from ​http://terraserver.microsoft.com/ogccapabilities.ashx looks like XML to me (maybe not valid WMS?).

For me, it returns a list of layers. No errors there. This is both in latest trunk and 0.8 branch.

The layers do not draw, however.

The problem is that terraserver uses different urls for GetCapabilities and GetMap:

​http://terraserver.microsoft.com/ogccapabilities.ashx

and

​http://terraservice.net/ogcmap.ashx

In my opinion, this is a strange interpretation of the WMS specification. Should qgis support several urls? I think if it is only terraserver, then not. If there are more wms servers like this out there, then probably yes.

Yes, this is strange, but legal. FWIW, in practice, I think this is one of the only WMS endpoints I've seen configured like this.

Apparently the URL has changed in meanwhile, now at: ​http://terraserver-usa.com/ogccapabilities.ashx

But the problem persits... for me it doesn't crash, just doesn't show any raster.

URL for GetMap request is advertised in GetCapabilities answer in element Capability -> Request -> GetMap -> DCPType -> HTTP -> Get -> OnlineResource

Correct. The bulletproof thing to do would be to invoke a GetCapabilities request, pick up this value and use that as the GetMap server URL.
