Abstract:

Trough introducing the definition and relation of several commonly coordinate system in measurement of geology exploration,we expound the conversion method among independent coordinate system,54 Beijing coordinate system,80 Xi’an coordinate system,WGS84 and 2000 National geodetic coordinate system,and their practical application. We analyze the development trend of the earth coordinate system,which shows that three -dimensional geocentric coordinate system will replace two-dimensional reference center coordinate system,multi-level network diagram will replace scale map.

Key words: 54 Beijing coordinate system, 80 Xi’an coordinate system, WGS84, 2000 National geodetic coordinate system, Measurement of geological exploration, Coordinate transformation
