Yes, but the aerial imagery isn't available *free* for anyone to use for 
anything. It's not edited and kept up-to-date until fresh images are 
taken. Some of the aerial imagery we use is years out of date.

It doesn't show names, it doesn't show rights of way, and it's of little 
use in wooded areas to see details below the tree cover, especially 
watercourses and footbridges. Try planning a footpath walk using only 
aerial imagery. :(

cheers,

Martin.
