Hi,
It should work out of the box. Reading
http://www.mapserver.org/ogc/wcs_server.html?searchterm=wcs shows for example
this example:
The following are optional GetCoverage parameters according to the WCS spec:
RESPONSE_CRS=epsg_code: Coordinate Reference System in which to express
coverage responses.
So to follow our above examples, a valid DescribeCoverage request would look
like:
http://my.host.com/cgi-bin/mapserv?map=mywcs.map&SERVICE=wcs&VERSION=1.0.0&REQUEST=GetCoverage
&coverage=bathymetry&CRS=EPSG:42304&BBOX=-2200000,-712631,3072800,3840000
&WIDTH=3199&HEIGHT=2833&FORMAT=GTiff
So all that is needed is to change the CRS and BBOX parameters in the request.
In addition, on Mapserver side there must be a PROJECTION block in mapfile to
tell Mapserver what is the native projection of coverage data.

getCoverageDescription request can return among other things a
<SupportedCRS> which informs clients that coverages can be requested in
a projection other than the coverages native format.
Is this possible with MapServer? If so can someone please give an
example of how to configure a .MAP file to allow this (or point me to
existing documentation on how to do this). Unfortunately, the secion on
SRS (CRS) '9.9.6' in the MapServer documentation is empty ... maybe it
was written by the same person who wrote the Geoserver WCS
documentation?
Thanks for any help.

Craig Dillabaugh
