been wondering the same thing lately, tho it probably wont be much use if the images are old, alot can change in 5years or even 6months, clear areas can become overgrown and vice-versa, here theres always new buildings and developments springing up everywhere, dont think u can beat physically going out and scouting for your spot and seeing the location for yourself, tho google earth maybe able to give you a rough idea of where to start looking.
