Hi Jukka, indeed I use a WCS 2.0 range query to select a point, this does mean that the client request needs to be adapted to the resolution of the coverage. In case the area matches multiple pixels, I plan to compute the average band value over all pixels, because that is also a valid use case.
I have also used range subsetting for band selection, although I did encounter some inconsistencies in the geoserver implementation which I had to work around, but this may have been specific to my custom data backend. best regards, Jeroen On Wednesday 12 November 2014 09:29:55 Rahkonen Jukka wrote: > Hi, > > Well, I was thinking simply X and Y for giving the point to be queried > because I thought that BBOX can't be a point.
