| 摘 要： | 三角高程测量以其快速、简便且能保证一定精度而应用于跨河水准测量，GPS高程精度的提高也为GPS替代水准测量成为可能，GPS测量不受通视条件限制的优点更适用于跨河高程测量。本例中用光电测距三角高程法进行跨河水准施测，通过相关精度分析，能达到国家三等水准测量的要求，并用GPS高程测量对同一测段进行比较检核。

| Abstract: | Trigonometric leveling is a fast,easy and in comparative high accuracy,it was applied to river-crossing leveling.With the raising of its elevation measurement accuracy,GPS was appropriate used in river-crossing leveling.In this paper,Trigonometric is used in river-crossing leveling.Analysing precision of the trigonometric leveling,it can achieve Third-class national standard of leveling,and GPS elevation measurement was used to check.its accuracy. |
