摘要
通过介绍地质勘查测量工作中常见的几种坐标系的定义和相互联系,阐述独立坐标系、54北京坐标系、80西安坐标系、WGS84以及2000国家大地坐标系之间的转换方法和实际运用,并且展望了我国大地坐标系的发展趋势,以三维地心坐标系替代二维参心坐标系,多级网络图取代比例尺地图。
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.
