Excellent job done!!! The map is very helpful and precise. Just small remarks - maybe they will be helpful to improve some locations.
Three Parallel Rivers of Yunnan Protected Areas - it is for sure not one point. Official description from http://whc.unesco.org/en/list/1083/
decribes the site as natural serial property consisting of 15 protected areas, grouped into eight clusters. I remember while visiting Potatso (Pudacao) National Park that maps were not precise but maybe it is better to utilise the map from official dossier (page 12) http://whc.unesco.org/uploads/nominations/1083.pdf
Los Glaciares National Park covers relatively big area starting from Fitz Roy Mountain (without the summit) further south to Lago Viedma, Lago Argentino and up to Chilean border (Lago Frias) - maybe for big national parks it will be better to show park boundaries ? Around the area of Fitz Roy there is also unknown border line (to the right of Fitz Roy summit). Real country border should be to the left.
Shilin Stone Forest (the most visited part of South China Karst) is located relatively close to Kunming https://www.google.com/maps/place/Shilin,+Kunming,+Yunnan,+Chinyemail@example.com,103.4171 734,10z/data=!3m1!4b1!4m2!3m1!1s0x36d01a523b68c991:0x6cd343b9b65de726
Ischigualasto National Park is located to the south of Talampaya NP. (should be 2 locations).
Also Atlantic Forest South-East Reserves is not one location as there are number of national parks and reserves. Maybe there will be possible to take exact coordinates from unesco website ? http://whc.unesco.org/en/list/893/multiple=1&unique_number=1045
As far as I know Bolivian site Jesuit Missions of the Chiquitos consist of 6 locationshttp://whc.unesco.org/en/list/529/multiple=1&unique_number=619
Anyway I am more than impressed for the effort done. This map is much, much better than official one on UNESCO website. And more helpful for planning further trips ...
