In the past two years, map providers like Google, Microsoft, and Yahoo have created tools that let anyone with an Internet connection layer their own geographic obsessions on top of ever-more-detailed road maps and satellite images.

It's become a sprawling, networked atlas — a "geoweb" that's expanding so quickly its outer edges are impossible to pin down. |
