LAST EDITED ON Sep-25-11 AT 04:36PM (MST)[p]Google actually hired a bunch of airplanes to fly the whole USA this year if they have not already. You should have better imagery in a year or two. They are doing 6 inch squares of the whole country. I agree that some google earth shots are way out of date. Google earth is the best I know of so far that is easy to use. I can't get my computer to use ARC Explorer so I don't know how well those are. I do use ARC Info at school and it is okay if you know what you are doing.
