摘要
我国数字海图的数据结构是在标准《数字海图数据字典》中进行定义的,是根据我国的自有技术体系进行设计的,与S-57标准相差较大。目前关于我国数字海图向S-57格式数据的转换研究较多,而S-57国际标准海图向我国数字海图的转换研究较少。文中在对S-57标准海图及我国数字海图编码和数据结构深入研究的基础上,实现S-57标准海图向我国数字海图的转换,有利于国内相关软件对国外海图数据的使用。
The data structure of China＇s digital chart defined in the standard ＂China nautical chart data dictionary＂,is designed according to our own technology system,which is very different with S-57 standards.At present there are a lot of papers about China＇s digital chart converted to S-57 format data,but few about international standard S-57 chart are converted to our digital chart.Based on the S-57 standard chart and our digital chart coding,through depth study of data structure,it presents the conversion of S-57 standard chart into China＇s digital chart.This is conducive for the domestic related softwares using the foreign seas data.
