Change of Map Datums – The Switch to WGS 1984

It was inevitable. At some point I was going to have to change to the WGS 1984 map datum from the Indian 1954 (Thailand-Vietnam) datum that has been used by the Thailand Caves Database. This procress has now been started, but it will be a long job and for the next couple of years there will be a mix of datums used on this site.
