It depends on wether you're going to invite the pilot for a nice

I think the most tricky part of the story is still to rectify and
adjust the resulting aerial imagery. If you managed to develop a

What happens is that the distance from lens to ground is different
over varying terrain, so it doesn't match what a map would be.

On the contrary: AFAIK, SRTM's are done by seeing the differences between

I have to admit to feeling very envious when I see the beautiful, crisp,
high-resolution aerial photographs that the People's Map guys are able to use.
It's such a waste that they have retreated into their own closed-off corner
rather than collaborating with OSM.

How does one go about calculating the field of view from the elevation and
resolution? Would you mind explaining that? Thank you very much.
