摘要
以电厂厂区和管线工程GPS水准高程为依据,从局部拟合法和大地水准面模型法分析了GPS拟合的精度,总结了GPS在厂区和带状地形图水准高程拟合精度的注意事项及直接应用WGS-84大地高差进行高程控制的方法。
With the engineering, this text introduces the detailed process about the surveying and settling the boundary of the land and Important factor. Putting forward how to help the developments unit complete the work of the surveying and settling boundary reasonably and availably with suggest.
