摘要
GPS高程拟合结果受研究区地形起伏、重力异常、数据质量、点位分布等复杂因素影响,很难有统通用的广泛适用性拟合模型。该文通过工程实例讨论了几种常用GPS高程拟合模型及其特点,得出有益结论。
GPS elevation fitting results are easy to be affected by many factors such as topographic relief, gravity anomaly, data quality, measuring point distribution, and so on. As a result, it is difficult to find a model which can be used in any place for GPS height fitting. This paper has a discussion on three GPS elevation fitting models and their characteristics.
