I am curious if anyone knows if, and how, it would be possible to configure GeoServer to provide download (GetCoverage) capabilities to multiple adjacent rasters. A GeoServer mosaic comes close, but provides only the single process image rather than the multiple "unaltered" raw originals that were used to build it.
Ideally, I'd like the user to be able treat the dataset as if it were uniform (e.g. DRGs for a state), but be able to access the original QQ that compose the mosaic. From what I can tell, GeoServer doesn't support this particular kind of interaction, but perhaps there exists a plugin I haven't yet heard of.
