摘要
在重力勘探工作中,重力成果的精度受重力观测点高程的影响尤为明显。在分析了EGM2008模型的精度基础上,提出一种基于该模型的重力观测点GPS高程转换方法,并利用某地区GPS水准资料,对转换方法的可行性进行验证分析,结果表明,这种方法完全适用于中小比例尺重力勘探工作。
The results of the gravity exploration work are evidently affected by the elevations of the gravitational observation points.In this paper,the GPS height transformation method is proposed on the basis of the accuracy of the EGM2008 model.The feasibility of the transformation method by using leveling data of an area is verified,and it is thus thought that this method is fully applicable to gravity exploration of medium and small scales.
