A closer look at China

Thanks to tianditu.cn, one can now take a closer look at China.

Map World - overseen by the State Bureau of Surveying and Mapping - is said to offer accuracy up to a resolution of 60 cm for more than 319 Chinese cities (as well as 3D maps in some of them). The site comes with the usual satellite view as well as street views. How does it compare with Google Maps? It really depends on your level of patience as Google displays images much faster. What about granularity? A look at Zhongnanhai (the center of power in Beijing) reveals that Google also has a slight advantage.

So far, the rest of the world is only roughly covered. Let’s see how quickly Tianditu catches up with Google maps in terms of speed and accuracy and whether it will expand beyond Chinese boundaries.
