I am old enough to remember when a vacation trip in the car was punctuated by “Highway Ends 1 Mile” signs, followed by a stretch of two lane highway. By the time I graduated from college, this part of taking a road trip had been eliminated, but now we have to realize that a lot of this highway infrastructure is getting pretty old and needs some serious work.
Over the past decade, many web and mobile applications have added maps to their user interfaces. Maps are a natural addition. Looking for a hotel or restaurant? See it on a map. Need direction to a store or attraction? See how to get there on a map. But there are other applications for mapping besides these.
