Terraserver WMS

[Ed McNierney]

Chip -

Are you certain that's the map file you're really using for the request
that produces that error?  The error message refers to a layer named
"ortho-18", and your map file has no layer of that name.

The Microsoft TerraServer WMS services do not support GIF image requests
- the only image type supported is JPEG.  Be sure to check the
GetCapabilities document carefully so you don't request things the
server can't provide.

Your EXTENT seems to indicate that you want the output map to be in some
sort of "geographic" projection, but you do not have a PROJECTION block
in your map file to specify the output projection you want.  If you use
this technique you should realize that you will have problems at UTM
zone edges, as the TerraServer UTM layers will not match properly at
zone boundaries.

I am trying to create a group of layers using WMS on Microsoft
Terraserver.

I run MapServer on an IIS6 web site as a CGI app.
I cannot seem to get this to work correctly.  Here is my Mapfile (at
least the pertinent sections:

Here is the error I get when I try to render the map:

msDrawMap(): WMS connection error. Failed to draw WMS layer named
'ortho-18'. This most likely happened because the remote WMS server
returned an invalid image, and XML exception or another unexpected
result in response to the GetMap request. Also check and make sure that
the layer's connection URL is valid. 
msDrawRaster(): Image handling error. Unrecognized or unsupported image
format
drawEPP(): Image handling error. EPPL7 support is not available.

What am I doing wrong?  Thanks in advance for your help.
