Nice maps Winston.
Here is a similar site desgined by a guy I know off a Phuket board, also has maps for various areas.

It dawned on me a while ago that I have seen that siammap site before Winnie, just checked the phuket board and he is another member, goes by the handle of Sunem, 49 year old guy from Sweden.
