基于DEM与重力场模型的GPS水准高程处理方法研究

GPS Level Height Manage Method Based on DEM and Gravity Model

  • 摘要: 提出了联合使用DEM模型与重力场模型的高程处理方法,用该方法处理了某市8800 km2范围内的15个水准高程数据,并与传统方法进行了比较分析,同时进行了重力场模型的地区匹配试验。试验发现,该方法适用于比高较大、测区范围广,且水准点数目少、分布情况不好的山区。

     

    Abstract: The height manage technique using DEM model and gravity model together is put forward,and this technique is used to manage one city fifteen level height data in 8 000 km2.The result is compared with that of tradition technique,and the gravity model matching test is done at the same time.The experimental resultshows that the technique to be the same with the mountainous area where is very wide and there is not enough level height data.
