摘要
利用可扩展标记语言 XML实现了 CNSDTF的矢量数据交换格式 ,生成了符合 W3C标准的 XSD Schema文档以及 CNSDTF附录样本文档所对应的 XML文档 .给出了 Schema文档的完整结构以及部分代表性元素的实现代码 ,并作出了相应的说明 .利用该文档 ,以 Altova的XMLSpy为辅助工具 ,生成了 CNSDTF附录 B中矢量数据交换格式样本的 XML文档 ,生成的XML文档完全符合网络矢量数据传输的条件 .该 Schema文档可以作为对应所有 XML数据文件的校验依据 ,并进一步成为书写。
The vector data transfer format of CNSDTF, geo\|spatial data transfer format, was implemented with the extensible markup language. An XSD schema document based on the W3C's standard was created and some XML documents corresponding to the documents in CNSDTF's appendix were developed synchronously. Complete structure of the schema document and implementing codes of some representative elements were given with the corresponding description. This schema document, with the help of Altova's XMLSpy, has been used to create an XML document corresponding to the sample vector data transfer format file given in the Appendix B of CNSDTF. The created XML document fully accords with the condition of vector data transmission in the network. The schema document can act as a verifying basis for all the corresponding XML data files and serve for the foundation of the source codes written to read these data files.
