Hey Naima, I may not have explained my issues super well, so sorry about that. Doing as you suggest is fine and easy enough to do, but since even the initial conversion from "local" projection to equirectangular results in some loss / distortion of information, any projections from that compiled equirectangular just propogate and amplifies those artifacts. E.g. if I go local projection -> equirectangular -> local projection I don't end up with precisely the same image, which is kind of suboptimal. I'm looking for something that retains all of the information from the various local projections--a "master" file, if you will--from which I can generate any arbitrary other projection without accumulating artifacts. Does that make sense?
