摘要
针对边境藏区基础测绘成果相对缺少,以及特殊的地理位置和自然环境造成水准测量、光电三角高程测量作业强度高、效率低的情况,本文提出了一种组合式GNSS高程测量方法,用于建立高程控制框架、高程控制点加密和碎部点测量。实践表明,该方法取代传统高程测量模式,可以高效率、低成本、较高精度地获取正常高,在藏区水电工程勘测项目中取得良好的工程应用效果,并得出一些有益结论。
A combined GNSS elevation measurement method is proposed to address the relative lack of basic surveying and mapping results in border Tibetan areas,as well as the high intensity and low efficiency of leveling and photoelectric triangulation operations caused by special geographical locations and natural environments.This method is used to establish an elevation control framework,encrypt elevation control points,and measure fragmented points.Practice has shown that this method replaces the traditional elevation measurement mode and can obtain normal heights with high efficiency,low cost,and high accuracy.It has achieved good engineering application results in hydropower engineering survey projects in Tibet and drawn some beneficial conclusions.
