A GetCoverage request sent to a WCS 1.0.0 server, with an invalid value for a parameter in the AxisDescription must trigger an exception

[nsavard]

When a GetCoverage request is sent to a WCS 1.0.0 server, which request has an invalid value for a parameter in the AxisDescription, must return an exception.

The concerned CITE test on the TEAM engine is: wcs1-0-0:getcoverage_operations-getcoverage_request-parameter-get-kvp-3

and the request is:

​http://dev1.lan.mapgears.com/manwe/cgi-bin/mswcs100_ogc_cite?&CrS=EPSG:4326&bands=WCS_PARAMETER_VALUE_INVALID&VeRsIoN=1.0.0&HeIgHt=100&ReQuEsT=GetCoverage&CoVeRaGe=ndvi&SeRvIcE=WCS&FoRmAt=GEOTIFF_INT16&BbOx=-97.7071758865421,41.0324719184183,-80.6778361148771,49.6650665681236&WiDtH=200

Steve: here, do we have to:

• handle BANDS parameter
• scan wcs_rangeset_axes for the term "bands"
• if it exists
  • scan wcs_bandcount for a match; if no match, throw exception
• if not
  • throw exception as not defined

I'm not entirely clear on the behavioiur here, but it looks like bands is passed as a "PARAMETER" type parameter in WCS 1.0.0, which gets picked up from a given DescribeCoverage operation?

Steve: if you can clarify here, that would be great.

Norm: can you send/post a testcase (minimal mapfile and data to reproduce)? I tried this against some local data and seems to have worked.

[tomkralidis]

Fixed:

• trunk (r7639)
• added a testcase to msautotest (r7640)

Props to Steve for guidance.

Norm: can you test and verify?

[tomkralidis]

FYI small fix to test metadata at r7641

[nsavard]

Tom: I'll check.

[tomkralidis]

Norm: any update on this one?

[nsavard]

This is fixed.
