I haven't been tracking everything on this list, but am very interested in
this concept. The "tools" side is interesting, but I'm really enamoured by
the GPS side of things. I would like to mirror the concept in Canada. Sure
we have a bit larger land-base :) but the same data access problems. I
would start at a municipal level. Having a pool of hardware available would
be very interesting. I wonder if it would even be possible to combine the
effort with a Geocaching.com promotion too. Folks could use the devices for
finding a geocache, but also collect other features along the way.
Is the image feature extraction the big problem area? At least using GPS you
could gather ground-truth sample points to help train the analysis.
Anyway, just thought I'd weigh in and say howdy.
