摘要
海图抽选对船舶驾驶员来说是一项十分重要而繁琐的工作.从减轻驾驶员工作量和科学管理抽选海图出发,研制了一种海图抽选系统.详细介绍了系统的设计和实现过程.系统将MapX控件嵌入到开发环境,方便浏览海图分区索引图界限图,并且建立海图分区索引图界限图和分区索引图之间的链接.经验证明,系统能够简单、快捷地抽选航经所需海图,并且直接将抽选的海图图号按航线顺序存入数据库,以备下次相同航线参考使用.
The selection of the nautical charts is a very important and complex job for the officer on board. The author developed a kind of selecting system for nautical charts to decrease the workload for the officer and manage the selected nautical charts scientifically. The author introduced in detail the design of the selecting system for nautical charts and the process of realizing it. Embedding MapX control into the develop- ing environment, it is convenient for the users to browse the limits of admiralty chart indexes, as well as to build the link between the limits of admiralty chart indexes and the index charts. This system is characteristic of simplizing the selecting of the nautical charts required for the navigation areas. And the numbers of these selected charts can be saved in sequence of route in database directly for the later reference use of the same route.
