[mapserver-users] Question About WCS

[Dillabough, Craig]

Hi,
I am brand new to MapServer, and I am trying to figure out WCS.

I've been following the instructions on
http://mapserver.org/ogc/wcs_server.html
and was making some progress as executing a GetCapabilities request
returns what I was expecting. However when I try to execute a
DescribeCoverage request I only see the following:

<?xml version='1.0' encoding="ISO-8859-1" ?>
<CoverageDescription
   version="1.0.0" 
   updateSequence="0" 
    ... Etc ....
   xsi:schemaLocation="http://www.opengis.net/wcs
http://schemas.opengis.net/wcs/1.0.0/describeCoverage.xsd">
</CoverageDescription>

Based on the tutorial I am also expecting to see a CoverageOffering
element as well with something like:

<CoverageOffering>
  <name>week19</name>
  <label>Week19</label>
 ... Etc ....
</CoverageOffering>

However, only the the CoverageDescription element shows up.

The relevant portions of my .map file are as follows:

MAP

    METADATA

      "wcs_rangeset_label"  "My label"    
    END  #Metadata

    PROJECTION
      AUTO  
    END
    DUMP TRUE ### required
  END #Layer
END # Map File

If anyone can see anything obvious as to why I am not getting the
expected result I would greatly appreciate some advice.

Cheers,
Craig
