Re: Aerial mapping
I tend to find that either Google Maps, or Microsoft have the best aerial maps. Will find one has better than the other for different areas.
The maps at 192.com are years out of date, at least for where I live, still have grass on the front garden which has been gravel for at least 6 or 7 years.
When there's always biscuits in the tin, where's the fun in biscuits?
