S-57海图数据在数字地图中的转换研究

Study on conversion of S-57 chart data in digital map

针对S-57海图读取转换复杂的问题,文中在分析S-57海图数据特点的基础上,重点研究了S-57海图数据内容解译,以及与基础地理信息数据的对应关系,设计了基于FME的数据转换流程,有效降低了S-57海图数据直接转换为基础地理信息数据的难度,为S-57海图数据在数字地图中的高效应用提供了技术支撑。

For the complicated problem of S-57 chart reading and conversion,in this paper,on the basis of analyzing the characteristics of S-57 chart data,focus on the interpretation of S-57 chart data content and the corresponding relationship with the basic geographic information data,the data conversion process based on FME was designed,which reduced effectively the difficulty of directly converting S-57 chart data into the basic geographic information data,which provided the technical support for the efficient application of S-57 chart data in the digital maps.
