"It's not a copy, we just got the inspiration somewhere else"
I was looking around Baidu.com (the Chinese Google) and stumbled upon their version of maps feature. While the normal view works pretty much like Google Maps, if you click on “三维” (Chinese for 3D) you'll be amazed what they put together. They remodeled Beijing as a SimCity-style 3D view, that is just impressively detailed aswel as beautiful. More or less everything inside the 4th ring road is covered. In some parts you can tell that it's up there for quite some time. The Sanlitun area is still under construction for example.
