摘要
地图投影和投影变换在地理信息系统中有十分重要的作用 ,投影变换的基本原理是通过数学的手段近似模拟地球曲面 .系统采用VisualC ++作为开发平台 ,开发了可以在十几种投影系统间进行多投影变换的变换模块 ,并且提供了四十余种投影参数作为选择 .
Map Projection and Projection Convert are important in GIS,.Map Projection is to simulate the spherical surface of the earth in the mathematics and map projection is to covert one method into another method.The system that takes Visual C++ as the tool can convert one projection type into another projection type in over ten projection type and provides over forty projection parameters.
