我国于2008年7月1日正式启用了CGCS2000坐标系，而地矿部门一直以来仍沿用1954年北京坐标系。为实现不同坐标系图件成果的有效共享，必须对地质物化探图件进行不同坐标系的相互转换。为此，笔者介绍利用MapGIS实现不同坐标系图件成果相互转换的方法，并通过真实数据对转换精度进行分析。试验结果表明，这种方法用于不同坐标系图件的转换是完全可行的。

Since July 1,2008,the CGCS2000 Coordinate System has been employed in China;nevertheless,Beijing Coordinate System of 1954 remains its utilization in geological and mineral departments.For the purpose of realizing the effective sharing of graphic docu-ment achievements of different coordinate systems,the transformation of geological,geophysical and geochemical exploration graphic documents must be carried out in different coordinate systems.This paper describes the inter-conversion method of graphic document a-chievements in different coordinate systems by using MapGIS.The transformation precision was analyzed with the real data.The test re-sult indicates that the method used in the graphic document transformation of different coordinate systems is completely feasible.
