I was wondering if anyone knows where to find the UNESCO world heritage list with boundaries? I can extract point data from the json feed for the map on the website http://whc.unesco.org/en/list via http://whc.unesco.org/?cid=31&l=en&mode=json but polygon or polyline data would be much more preferable.
Edit: I was particularly interested in Australia, but it would be good to know where to go to find this sort of info worldwide, so if you have other countries, feel free to post them up as well.
