Hi there, In Vietnam, before 2000, Vietnam used Hanoi1972 datum that is the same as the Indiana 1960 - Vietnam Conson datum. From 2000 they have built up new datum called VN2000. I have got the following link talking about the Vietnamese datum. Hope that It would help you. http://www.cigc.com.vn/thongtin.htm
