I have a series of coordinates for locations in Sichuan Province China that I need to convert so that I can use them in Google Earth. The coordinates are "1954 Beijing coordinates system" and show up as 3470081.60 36512300.88 with NO additional information other than elevation figures.
I ma pretty sure that the coordinate above corresponds with LAT 31.353305 LONG 108.131089 in WGS84 (Eastern Sichuan Province).
I'm struggling to understand what format the coordinates themselves are in - is it some type of modified MGRS? I'm assuming there are two steps I need to follow here, firstly to convert the coordinate system itself and then secondly to covert from the Chinese Datum to WGS84....right?
