Great post polaroid. I am using it to generate approximate hazard zones around LNG (liquefied natural gas) faciities. If possible, a kml that generates a "buffer-zone" around a line/path would be extremely useful too. I don't have the know-how to do that and don't know how difficult it would be. But if it's not too much and you or someone else out there has the interest, that would be very useful and much appreciated too.

Google Earth is fantastic, and people like you are doing a great service in showing that it's a whole lot more than just flying around the world looking at cool stuff. Thanks
