Shiphandling simulator is a device that can partly imitate the true environment at sea ， and is specially designed to satisfy marine education and trains and maritime research etc . one of its key techniques is to create the virtual environment at sea ， and the terrain is its important component . according to the needs of the real time visual display of the shiphandling simulator ， this paper analyses the requirements of the geometry precision of the important islands and background hills which are within the ships ' visible scope ， and brings forward the modeling methods of the hill ' s pileup and the hill ' s silhouette edges based on contour lines . it also presents the definition of error that the hill ' s silhouette edges graph has been given and the effective scope of application ， and firstly established the error criterion of terrain model that is built in shiphandling simulator . with these two kinds of method ， the size of data storage can be minimized greatly ， and the requirements of high update rate and geometry precision for the real time visual display of the shiphandling simulator can be satisfied 船舶操纵模拟器是一种能够部分模仿海上真实情况,专门为满足航海教育与培训、航海技术研究等目的而设计研制的装置，其核心技术之一是海上视景模拟，而地形地貌是海上视景中的重要组成部分.根据船舶操纵模拟器实时视景显示的需要，在分析航行船舶对可视范围内重要岛屿与背景山脉的几何精度要求的基础上，提出了基于等高线的山形堆积建模和山形轮廓建模方法，并给出了山形轮廓图形的误差定义、有效适用范围，以及船舶操纵模拟器中地形建模的误差准则，该方法生成图形的数据量较小，其图形更新速率与几何精度能达到船舶操纵模拟器实时视景显示的要求
The construction of harbors and fairways belongs to a typical capital denseness industry , which takes a long time to build and to gain , a little carelessness may result in a huge loss , hereon the ship maneuvering simulator can exert it " s advantage , makes some contribution for our country " s harbors and fairways 港池和航道的建设，属典型的资金密集型产业，是建设、投资回报期都比较长的行业，稍有不慎，就会造成巨大浪费或亏损，而船舶操纵模拟器在此就可以发挥其优势，能为我国的港航建设作出应有的贡献。
There are many factors must be desided such as width ; depth ; ship ' s turning area ; ship ' s stop distance during the design of shanghai deep - water channel . very large container vessels . navigating at the channel with the affections certain wind , currents , seas and other influences , may cause more huge damage and expenditures for the accidents without safety operation . some date for channel design to very large container vessels has been gone beyond in " design code of general layout for sea port " and needs to replenish , modify . the purpose of this study is : to choice the ship form , mainly ship ' s overall size ; draft , according to design of shanghai deep - water port and development of container , then to get the date of width and depth of channel through simulator tests 对8000teu 、 5250teu超大型集装箱船舶的航道宽度设计已超出了该规范的规定范畴，急需补充甚至修改。本课题研究的目的是根据洋山深水港设计规划和集装箱船舶的发展趋势，通过研究、分析、比较，选择最合适的船型，尤其是船舶主尺度和船舶吃水。在此基础上，采用船舶操纵模拟器进行航行模拟研究，在大量模拟研究情况下，得出进港航道所需的航道宽度和深度。
