Hi j-wills,

many people do mapping from satellite images. We are e.g. allowed to use the Bing Areal images for this. If you want to help us feel free to do it (but please do not copy data from copyright protected sources). There is many work to do in Thailand and especially in Bangkok. Please do not expect that someone will fix “this way” just for you soon.

The mapnik renderer seems to combine the name Bangkok. It seems to use the thai-word “Krung Thep Mahanakhon” and in brackets the word “Bangkok”. I think this is OK for most people.
