利用Android移动操作系统平台,设计并实现了一种移动电子海图显示系统.对系统的组织结构,以及S57数据的解析与转换、坐标投影与坐标转换、海图的检索与物标显示等关键技术进行重点论述.实现的系统显示海图准确美观,在智能手机和平板上运行快速稳定,在船舶导航、船舶监控等领域具有广阔的推广应用前景.
Abstract
One kind of mobile electronic nautical chart display system was designed and implemented based on the Android platform. The architecture and functional modules of the system, and the key technologies including parsing and conversion of S57 format electronic nautical chart data, projection transformation, index and search of charts, symbol displaying of objects were described detailedly. The system displays nautical charts precisely and elegantly, and can run stably and smoothly on intelligent mobile phones and tablets. It has a good prospect in the field of shipping information application such as nautical navigation, vessel tracking.
