精化山西区域内大地水准面的思考

本文概述了确定大地水准面的一般方法，并指出精化山西区域的大地水准面 现阶段应该采用ＧＰＳ水准方法，然后从埋论上分析了大地水准面精度．地表地形，ＧＰＳ水 准点间距三者之间的关系最后还论述了大地水准而的成果形成以及如何进行质量控制． 本文所述的ＣＰＳ水准方法，用于确定高程异常时。

In this paper general methods of determination of Geoid were represented .The authors suggested that GPS/leveltechnique should be applyed in improving the Geoid of shanxi province recently,and derived the relations from the precise of the Geold.the terrain and the distance between GPS/level points.At last the expressing form and the quality of the improved Geoid were studied.
