Google maps is impressive. Not only can you see satellite images, but you have street view as well - this has helped me confirm the exact location of some benches I've photographed.
It also allows you to generate your own maps, and that cam in handy when I wanted an over view of the location of all the benches I'd visited.
Creating the map was very easy as I have a csv file with all the details about the benches, I just had to upload it to google and let them to the rest.
The beauty of this map is that's it's clickable, so locating a given bench is very easy.
thank you google.
