摘要
介绍了利用MAPGIS投影变换子系统对地质勘查成果图件进行投影转换的方法步骤,同时用实例说明了不同坐标系之间投影转换过程中的参数选择,对计算机制图具有一定的借鉴作用。
The method and steps of MAPGIS projection transformation subsystem to the geologic exploration result map is introduced in this paper,meanwhile,explained parameters choice taking some concrete examples in different coordinate projection transformation,which has a given use for reference for computer-aided graphic system.
