You've done a really great job. It's wonderful to discover all the places which you have made available.
However it seems to be that some - especially the ones in Thailand, the country where I happen to live at the moment - of the placemarks are far out of place. For example the ancient city of Sukothai, Ayutthaya or in Laos the city "Luang Prabang" which actully lies next to the banks of the Mekong river but appears in GE in the middle of mountains.
If you need any assistance in correcting the coordinates, just let me know.
