摘　　要：本文介绍了能够读取S-57格式的ISO 8211Lib库和开源库OGR,详细研究了利用开源库OGR读取S-57文件的方法及利用标准模板库的map-vector结构实现S-57向Shapefile转存的方法,重点探讨了空间参考系、属性要素及图形要素的转换方法,构建了S-57和Shapefile符号库间转换XML配置文件。实践表明,转换结果符合精度要求。This paper introduces ISO 8211 Lib which can read S-57 datasets and OGR library,and probes the methods to read the S-57 documents by the open source library OGR and the methods to transform S-57 to shapefile by map-vector structure of standard template library.Then it focuses on the transforming method of spatial reference,attribute elements and graphic elements,and constructed XML configuration files between S-57 and Shapefile symbol libraries.Practice shows that the conversion results meet the accuracy requirements.
