Google Maps API Countries and Regions as Polygons

Question

I have a question on how to highlight areas on a Google map. I know how to place polygons on a map. This is pretty simple and scary. The problem is that I do not have access to such data, and I do not know any sources. From my database, I get lat / lon for a specific place, and I need to have data about their borders. Do you know any free or paid database that contains data on landfills for all countries / regions of the world?

Thanks in advance.
