摘　　要：在地质行业里,由于野外地质工作人员对坐标系统不够了解,导致野外所采集的坐标经转换后投影到地形图上与实际情况不符,也使提交的成果数据误差较大。从理论上解释了各坐标系统之间的关系,并从野外所采集的数据投影到地形图,最终转换到成果数据的方法做了进一步的探索。In the geological industry,because the geological fieldworkers do not know enough about the coordinate system,the coordinates transformed from the field collection ones and projected onto the topographic map are inconsistent with the actual situation,and errors of submitted results data are larger.This paper explains the relationship among various coordinate systems,and makes further exploration on the method for projecting the data collected from the field onto a topographical map and finally transforming them into the results data.
