广义延拓法在似大地水准面模型精化中的应用
Application of generalized extended method on refining quasi-Geoid model
摘要
Abstract
To determine the accuracy of generalized extended method in quasi-Geoid model refinement, this study investigated the relationship between the data of geodetic height by GPS and the data of normal height by leveling based on theoretical analysis and experiment.In addition, the study derived a mathematical model of generalized extended method.The fitting results were validated by the experimental data from Tiefa mining area.The results show that the accuracy and computing time of generalized extended method exceed those of finite element method [1].Without using other data, the accuracy of generalized extended method can achieve the requirement of fourth leveling in hilly area.The results are useful and are of significance to quasi-Geoid model refinement.关键词
