摘要
海区的离散化处理是进行航路规划的重要环节之一,本文论述了海区离散化和网格点信息获取方法.采用船位误差作为网格大小的依据,分析了船位误差的影响因素和计算方法;论述了水深点信息获取和曲面拟合网格点水深信息的方法.
The discretization of sea area is an important progress in route-planning.This paper discusses the way of discretization and obtaining each grid＇s information.Ship＇s location error is adopted to obtain the size of each grid.The calculation method of factors which will impact ship＇s location error is analysed.More over,this paper discusses the way to obtain information of water depth point and how to use curved surface to fit these datum.
