摘要
通过对GPS高程拟合与几何水准高程的比较与分析,在绘制矿区地形图中,完全可以用GPS高程替代传统的几何水准高程,在矿区高程控制中有着广泛的应用前景,具有一定的社会效益和实用价值。
Through to the GPS elevation fitting and the geometry standard elevation comparison and the analysis, in drawing up in the mining area topographic diagram, definitely may substitute the GPS elevation for the traditional geometry standard elevation, which has a widespread application prospect in the mining area elevation control, and has acertain social efficiency and practical value.
