GIS地图投影变换在地质工作中的应用

摘要

According to the problems encountered in practice, expounds the relationship between datum, spheroid, coordinate system and map projection, which involved projection transformation. the application of projection transformation in geological studies are discussed, and states the GIS projection combining with the example.%结合实际工作中所遇到的问题，对投影变换中所涉及到的基准面、椭球体、坐标系统及地图投影之间关系进行阐述，进一步对投影变换在地质科学研究中的应用进行了讨论，并结合实例对GIS投影进行论述。
