There be dragons! Mapping is all fun and games until somehow someone ends up trying to learn javascript or looses an eye! 
Anyway, figured I’d have a little poke at the list, I’m not 100% about some of the the Asian ones. @Cara, might be able to verify them what with actually having visited the countries in question which rather beats my poor-man’s Google pilgrimage. In the order they appear on the AfB site:
###Sri Lanka
Ayya Khema International Meditation Centre : 6.76728, 80.03449 (it’s on the AfB list, but I guess strictly speaking it might not belong within the bounds of this map as it’s not a Bhikkhuni Monastery - if it does, however, then Milntuim Hermitage absolutely does: 56.34691, -4.00535)
Sakyadhita Training Center: 6.76192, 79.90189
Bhikkhuni Training Centre: 6.93674,80.09511 (Kahatapitiya, 12418 Horana, Sri Lanka)
Mahamevnawa Nuns’ Monastery (Sri Lanka): 7.341587,80.251996
##thailand
Thippayasathandhamma Bhikkhuni Arama: 7.15529, 100.53503
Suan Siridhamma Center: 13.62638, 100.18731 (very unsure about this one)
International Women’s Meditation Center Foundation: 12.64558, 101.37536
###USA
Awakening Truth: 38.43115, -122.66691
