As shown on Television, I compare the Bangkok Map from the police with the Map Data available in OSM.

Please see for yourself

The police version:

![Police]https://drive.google.com/file/d/0By-zY9AlHqXIOHd5MTZubnBxRzg/edit?usp=sharing

Now the Police Version with OpenStreetmap Data overlay!

![osm]https://drive.google.com/file/d/0By-zY9AlHqXIaFN1R2NtS0s0WEk/edit?usp=sharing

What a difference!

PS: (I guess that the Bangkok police might have a better map somewhere else available :-)
