Oh, interesting! I've thought about going for larger areas, but most of the places I've been interested in looking at so far (kelp forests, wetlands) are fairly small, and it's lower anxiety to do low and slow flights where I don't have to worry about local air traffic. As a result, I've tried mostly aiming at high-resolution rather than large area. Of course, that helps with the size overhead as well--my existing computing setup is almost never the bottleneck. If you end up making any of your work public, I'd definitely be interested in taking a look--I've been starting to think about larger area surveys as well.
