The virtual world has never been more connected to the real one. Satellite imagery and geography markup language are all over the Web, and GPS receivers come built into cell phones and other everyday gadgets. All the overlords of Internet search – Google, MSN, Yahoo!, even Amazon’s – provide cartographic results embedded with information.

Augmented reality is the latest benchmark of the digital age.

How did we get here? This technology used to be top-secret government stuff. Then, in the 1980s, McDonald’s dumped thousands into buying satellite images and developing software called Quintillion, which predicted the growth of cities and school districts.

In 2005, anyone can have a god’s-eye view. MapQuest began doing rudimentary online maps in 1996.
