Hi,
Perhaps we should have some WCS GET demo request. I have an initial list here:
http://localhost:8080/geoserver/ows?service=wcs&version=1.1.1&request=GetCapabilities
http://localhost:8080/geoserver/ows?service=wcs&version=1.1.1&request=DescribeCoverage&identifiers=mosaic
http://localhost:8080/geoserver/ows?service=wcs&version=1.1.1&request=GetCoverage&identifier=mosaic&BoundingBox=41,8,42,9,urn:ogc:def:crs:EPSG:4326&RangeSubset=contents&format=image/png&store=true
http://localhost:8080/geoserver/ows?service=wcs&version=1.1.1&request=GetCoverage&identifier=mosaic&BoundingBox=41,8,42,9,urn:ogc:def:crs:EPSG:4326&RangeSubset=contents&format=image/png&store=true&GridOffsets=0.01,0,0,0.01
->requires 2
http://localhost:8080/geoserver/ows?service=wcs&version=1.1.1&request=GetCoverage&identifier=mosaic&BoundingBox=41,8,42,9,urn:ogc:def:crs:EPSG:4326&RangeSubset=contents&format=image/png&store=true&GridOffsets=0.01,0.01
->works
http://localhost:8080/geoserver/ows?service=wcs&version=1.1.1&request=GetCoverage&identifier=mosaic&BoundingBox=41,8,42,9,urn:ogc:def:crs:EPSG:4326&RangeSubset=contents&format=image/png&store=true&GridOffsets=0.001,0.001
->gives different size

Aihe: Re: [Geoserver-users] WCS Cell Size
I'm not going to be of much help on this.
I've noticed some very odd stuff with WCS.
http://sedac.ciesin.columbia.edu/geoserver/ows?SERVICE=WCS&VERSION=1.1.1&REQUEST=DescribeCoverage&IDENTIFIERS=species-v1-global-amphibian-family-richness
Things I've observed are:
* The grid definition's axis ordering doesn't obey the coordinate reference
systems' axis ordering.
**
http://osgeo-org.1560.x6.nabble.com/WCS-Img-Sample-GridOrigin-and-GridOffsets-appear-flipped-td5158701.html
** In your example, the origin values look like they should be reversed, but I
don't believe it's something you did.
* Apparent upsampling of data.
**
http://osgeo-org.1560.x6.nabble.com/WCS-GetCoverage-The-smaller-the-bounding-box-the-more-data-you-get-td5158916.html
The offsets indicate a direction (sign) and distance from the origin. Your
current origin is -179.991667 84.99436. Did you try defining the entire output
grid in your KVP request to see if it gets you closer to what you want? (i.e.,
Adding your GridOrigin.)

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
