[OSM-talk] Aerial Photographs (was: People's Map)

[Keith Ng]

Couldn't the process of obtaining aerial photographs be made much cheaper
with RC planes? I am not sure if it would work but setting the RC plane on
auto pilot and attaching a camera with continuous shooting mode might make
the process simpler.

a commentator said:"Just wanted to make it clear that we (Pict'Earth) are
willing to help anyone from the DIYDrones group to get their UAV imagery
processed and published in OAM, just let us know. If you can fly with a
logging GPS and a digicam, our Win32 software will get you part of the way
and we can help with the rest of the manual bits until we get it truly
automatic."
