We all use maps, but how much thought do you give them? Justin Miller and the team at Mapbox give them a whole lot of thought. Map box supplies maps and map data to application developers to use in apps like Pinterest, Foursquare and more. Justin gives us a look at the world of iOS maps, the kinds of information they deliver to us, and the kinds of information that developers can obtain from them.
