I haven’t seen this widely publicised yet.
Google Street View have just launched their next phase and they now cover over 95% of the UK roads. I’ve had a quick look around and it covers lots of quite remote parts which is ideal for planning a parking spot for activations etc.
If you’re not familiar with it, go here:
enter in a postcode, location etc. then pick up and drag the little yellow man (next to the “zoom” bar) and drop him on the road you’re interested in and have a look around. Drag and click to move your view perspective.
Another useful planning tool.
