It's Chinese, which is a three-dimensional map of GuangZhou city, the labels are the names of places.
and as rywang mentioned above, there is a 3d map http://sh.o.cn/ for ShangHai too
Actually, I was making two jokes, the second being how the map was out of date the instance it was published, because of how quickly a city's buildings and streets can change in China.
Still, it is very nicely done!
