| Abstract: | In view of the facts that the near-region terrain correction is very important for gravity survey and there exists no other better terrain correction method, this paper analyzed the labor, equipment, accuracy, and integrated efficiency of four methods, i. e. , visual estimation, laser range finder, forest compass and RTK, and then summarized the advantages and disadvantages of these four methods. The results of this experimental study provide a better application and demonstration effect for the near-region terrain correction. |
