基于MapX的电子海图显示系统开发

提出一种新的面向S-57国际标准电子海图的显示方案。在分析S-57等标准的基础上,对电子海图进行解封装,建立一种Access数据库与空间二进制文件相结合的数据结构,结合MapX控件,在Delphi平台上实现电子海图的绘制、显示与操作。该方案成功地应用于某船舶监测系统,具有良好的显示和操作效果,达到了预期的性能指标。

Electronic Chart Display System Development Based on MapX

A new display scenario of electronic chart orienting S-57 International standards was brought forward.Based on the analysis of corresponding standards,the electronic chart's de-capsulation was achieved and a data structure combined Access database with binary file was built.Utilizing MapX,the electronic chart's protraction,display and manipulation was realized on Delphi platform.The scenario had been applied to a ship monitoring system successfully and showed a better display and manipulation,it not only achieves the perspective capability index,but also makes a profound effect on application of electronic chart navigation systems.
