Hi all, Working with Geoserver as a WCS we discovered that requesting a GeoTIFF in the same projection as the original GeoTIFF produces a shifted dataset. (http://jira.codehaus.org/browse/GEOS-3702) The shift is small, less than one pixel of the original dataset, but with a coarse dataset of 100m/pixel it can be 70meters. The Geoserver people are aware of the problem and at some point in time will fix it I'm sure, but it prompted me to test other OSS WCS servers (mapserver and deegree). Both of them showed a shift of the data as well. Deegree has about the same error as Geoserver, while Mapserver does a better job but is still off.
I know there have been speed tests between different WMS services, but I'm wondering has there been any data-quality/accuracy test been done between WMS and/or WCS services?
