一种高效的多波束全覆盖测量工作量估算方法

摘要

With the powerful ability of the volume calculation of the Surfer software,and the flexible programming of the Scripter module,combined with the general bathymetric chart of the oceans(GEBCO) DTM database, this paper achieved the effort estimation in the multibeam project planning automatically and more accurately. This can be very helpful for the hydrographer. Finally, this paper used the history survey data of several projects to verify the precision of this method,obtaining that the average error is about 4% ,and achieved satisfactory results.%利用Surfer软件强大的土方量计算功能,及其Scripter模块的编程功能,结合大洋水深图(GEBCO)的水深数据,实现了全自动估算多波束全覆盖测量野外工作量的方法,旨在为相关测量单位进行工作量估算时提供参考与帮助.最后通过对多个工区的历史测量数据进行验证,采用本方法获得的工作量与实际工作量的平均误差为4％左右,取得了满意的效果.
