As far as i know the Google Maps API doesnt expose that info. One thing's for sure is they have it.... how else do they draw the borders? All in all they dont expose that area of the maps ability to draw borders unless you want to reverse engineer the maps player and see what's happening. Anyway. the best way, well maybe not the best but the way to do it is to use the GPolygon Class from the API and somehow build your Country's Border Vertex Data. Once you have that data loaded up you can can then fill the polygon as needed. Quoting ambrose kimaiyo <mail2ambrose@gmail.com>:

Hi Skunks,

I am working with Google maps for a web application. I have an issue I have to sort, that is having an entire country highlighted with a given color (Afica). The data will be dynamic but if i can get a way on how to do this i will be set.

Regards,

Ambrose
