But you could use Google maps to spot possible targets to do this on.
I work for a roofing company that does flat roof restoration. Generally these roofs are over 50,000 sq. Ft. I can go to google maps and find any roof I want and get a good estimation of the size using google maps. I was wondering if software could be created that would find all flat roofs over a certain size in a given location (ex. Chicago, IL) using google maps or similar systems. This would be very helpful for the business. I have no idea if this would be possible. Any of your ideas would be greatly appreciated!
