Spare time, I had, and wanted to see where someone was physically located in China. The place is a small town on the border of Shanxi and Inner Mongolia, on the Yellow River. What were the odds that I could find her exact location and get a satellite photo of her building?
I started using Google Maps, which was pretty helpful. Considering that Google is not allowed in China, they still had maps of the small city and specifically the 1km section of road that interested me. The sat photo showed great detail, as you can see, but the roads from the diagram did not coordinate very well with the sat map. In fact they were really so far off that some roads went underwater, like tunnels.
