Historical reasons, it's part of a services-chain and originally they thought that they would need the coverage data as geotiff. Later on it was found that PNG was good enough, but it was too late to change the entire chain to request WMS instead of WCS. > > Steven > > > > On Nov 20, 2009, at 4:33 PM, Simone Giannecchini wrote: > >> Ciao Steven, >> a few questions: >> >> 1> can you briefly describe your use case, especially in terms of data? >> 2> why are you trying to force the WCS to generate an image?
