Hi Andrea,
Thanks for the feedback and braindump, much appreciated. I'm back in town
this week and looking further into this next week. I think we are going to
be trying to achieve a rough, throw away first pass at this and let that
inform the existing ImageMosaic API change proposal and further work on
dynamic reprojection in the ImageMosaic.
Personally I'd like to see the ImageMosaic opened up in such a way that
dynamic reprojection could be done as a plugin without effectively
impacting how it currently operates. I'm hoping that sometime next week I
can take a second pass through Niel's API change proposal and solicit more
feedback on it.
Cheers,
Devon
