Shapefile地图与S-57海图集成与显示方法研究

Discussion on the Integration and Display of Shapefile Map and S-57 Chart

基于通用的GIS地图数据格式Shapefile,实现陆地图与海图的集成。通过分析对比Shapefile文件和S-57标准文件的结构,提出了二者的数据集成与显示方法,设计了它们的空间数据共享模型,结合该模型开发了能同时解译Shapefile和S-57数据并集成显示的GIS组件。研究表明:基于该组件,能实现陆地图和海图的无缝融合,可应用于水陆一体化的GIS信息管理,弥补了以往单一GIS的不足,能很好的满足现代物流信息管理的需求。

Based on the common GIS data format Shapefile, this paper integrated the land map and Chart. On the basis of analysis of Shapefile and S-57 Chart file structure, for the Shapefile and S-57 Chart data, a method to integrate and display was proposed, and a Spatial Data Shared Model was designed. Combined with the model, paper implemented a GIS compo- nent which can explain and integrate Shapefile and S-57 Chart. This study shows that based on the GIS component, the land map and Chart can merged together seamlessly. Applied to integrated management of land and sea GIS information, the GIS component can make up for the lack of single data GIS and meet well of the needs of modern Logistics Management.
