Good catch Jukka.
Kytt, your grid definition is citing this default grid type: 2dGridIn2dCrs
That means you'd have to use 4 values for your offsets. Also, keep your
signon the numbers. The grid knows how it's defined. You can see this
by describing the coverage. (The DescribeCoverage operation.)
Typically you'll have a step to the right and a step down as most grids
seem to have an origin in the top left corner. So the next node would
be down and to the right. If you want to use two values, you'd have to
provide a GridType to the request and use 2dSimpleGrid. Then you can
omit the 0,0 part of the GridOffsets. I'm not sure if that works in
GeoServer or not, so YMMV.
Just take a look at the WCS 1.1.0 specification, page 47 for some hints.

Hi,
It would be much easier for us if you can repeat the issue with some of the
Geoserver demo layers. Without your data we are somewhat blind.
Do you get correct pixel size with WCS 1.0.0 and resx + resy? I have not
played at all with WCS 1.1.0 yet and I not know when GridOffsets can be
expressed with two numbers and when it should have four. Have you alreasy tried
GroDOffsets=0.008333,,0,0,-0.008333?

Hello and good day,
I have what I think is a simple question. I am trying to make a WCS
1.1.1 GetCoverage request to a Geoserver running version 2.5
http://sedac.ciesin.columbia.edu/geoserver/ows?SERVICE=WCS&VERSION=1.1.
1&REQUEST=GetCoverage&IDENTIFIER=species-v1-global-amphibian-family-
richness&FORMAT=image%2Ftiff&BOUNDINGBOX=42.0,16.0,45.5,18.5,urn:ogc:
def:crs:EPSG:4326&RangeSubset=contents&GridOffsets=0.008333,0.008333
For some reason the TIFF that is returned has an irregular cell size of:
0.005952381, 0.011666667
The expected cell size are the contents of GridOffsets=0.008333,0.008333
What am I doing wrong?
Many thanks,
Kytt
