海洋重力资料整理技术与软件实现

MARINE GRAVITY DATA PROCESSING TECHNOLOGY AND SOFTWARE REALIZATION

摘要: 针对海洋重力测量成果规范化整理与重力异常计算软件开发问题,重点讨论了重力掉格校正与测线文件获取的可视化方法;引入贝塞尔方法计算船速和航向,并进行厄特渥斯校正。在此基础上,依据海洋重力调查规范,基于图形可视化技术开发了一套具有人机交互功能的海洋重力资料整理软件。

Abstract: Technical problems remain in marine gravity data processing and anomaly calculation. In this paper we proposed a visual method for correcting gravimeter calibration error and extracting surveying-line files. Bessel method is used to calculate survey ship's velocity and course,and then do the Eötvös correction. Based on these techniques and according to the requirement of the national standard (GB/T 12763.8-2007), the authors developed a marine gravity data processing software characterized by visualization and human-computer interaction.
