摘要
介绍利用似大地水准面模型在海口市主城区内地面进行GPS高程转换的具体方法。实践证明,只要工作方法得当,利用似大地水准面模型在人、车拥挤和建筑物、电力、通讯等设施密集的城市主城区内进行地面GPS高程转换,其结果可以达到有关规范的等级高程控制要求,从而达到节约人力、物力、财力,提高测量工作效率的目的。
The detail method was introduced for application of quasi-geoid model to GPS height converting in the earth＇s surface of main urban region of Haikou. It＇s proved when we take suitable surveying method to apply quasigeoid model to GPS height converting in the earth＇s surface of main urban region crowded with man, vehcle and building, electric power, communication facility, so that the results can be satisfied with the demand of gradeheight control for related standard, the manual labor, material and financial resources decreased and the surveying work efficiency raised.
