【摘要】 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。更多还原

【Abstract】 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 document 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 achievements in different coordinate systems by using MapGIS.The transformation precision was analyzed with the real data.The test result indicates that the method used in the graphic document transformation of different coordinate systems is completely feasible.更多还原
