for 1000 UKP you can probably get 8-10 handheld GPS units to lend to 
people... imho, this would be highly productive and potentially 
limitless in terms of the spatial extent of the mapping.

maybe organising a GPS-a-thon with a small reward for the person who 
uploads the most new features would get people's friendly competition 
going a bit?

its my opinion that satellite photos are poor value for money compared 
to community GPS capture. large features, such as forest boundaries, 
lakes, etc... can be drawn over landsat data, which is free. smaller 
features, for which landsat is not high enough quality, are better 
captured at ground level, where the signs, road types and other 
interesting features can be noted.

according to my (very rough) calculations, 1000 UKP buys (at current 
national average prices) about 6000 miles of car travel, or several 
GPS units or a month of someone's time to wander/drive around 
collecting tracks.

or a massive prize for the GPS-a-thon ;-)

cya,
