摘要
概述了济南市似大地水准面精化项目的基本情况,详细讨论了似大地水准面精化成果外部检核方法,并按平原和山区两种不同地形评定了外部检核精度,得到一些较为实用的结论。
This paper summarized the basic content of quasi-geoid determining in JiNan, then detailedly introduced the methods for result check of quasi-geoid determining, evaluated the precision according to two different terrain, and the corresponding conclusion are analysed.
