GPS船用导航仪中嵌入式电子海图数据的制作与显示

Manufacture and display of Embedded electron nautical chart in Marine GPS navigation instrument

在嵌入式GPS电子海图显示系统中,通过对ArcMap地图软件进行定制等功能的二次开发,不仅可一次性录入点线面输入时所有的参数,而且在完成修改后可使用定制工具直接输出特殊的点数据文本文件、面数据文本文件和线数据文本文件。可大大减小海图文件数据的容量。

In the embedded GPS Electronic Chart Display System,Through re-development for map software of ArcMap such as custom-made etc,not only recording all of parameters when inputing dot,line and surface,but also can use costom-made tools to out-put special dot data text file,surface data text file and line data text file after finishing modify.can greatly reduce the chart file data capacity.
