Jukka:

If I issue the request in the same units as the coverage (as shown
below) the request works fine.

REQUEST=GetCoverage

COVERAGE=landsat_test

CRS=EPSG:2956

BBOX=410000,5726000,411000,5727000

RESX=30

RESY=30

FORMAT=GTiff

RESPONSE_CRS=EPSG:2956

If I issue the request in another projection (as shown below) the
request has issues with reprojection.

REQUEST=GetCoverage

COVERAGE=landsat_test

CRS=EPSG:4269

BBOX=-113.179,51.761,-113.177,51.763

RESX=30

RESY=30

FORMAT=GTiff

RESPONSE_CRS=EPSG:3400

The service exception I get is 

<ServiceException code="NoApplicableCode"
locator="bbox">msWCSGetCoverage(): WCS server error. Requested BBOX
(-98.179,66.761,-98.179,66.761) is outside requested coverage BBOX
(281685,5612685,538515,5840415)</ServiceException>

As you can see, the requested BBOX the server picks up is nowhere near
the BBOX I provide in the URL.  The basic content of my map file is
shown below.  As you can see the layer is WMS as well as WCS and the WMS
call works fine.

Any help would be appreciated.

Hi,

Your layer definitions and the GetCoverare request you were using would
help pretty much.

the GetCapabilities and DescribeCoverage requests.  However, when I

issue a GetCoverage request I get a bounding box error due to bad

coordinates.  The layer is also set up as a WMS layer (1.1.1) and a

GetMap request works fine.  The metadata ows_srs and ows_resolution

parameters are being used in the map file and these work fine for WMS

requests.  Should I be using version 1.1.0?
