基于XML标准的天津市核定用地成图与检查系统设计及实现

Design and Implementation of Tianjin Verify Land Mapping and Checking System Based on XML Standard File

天津市对核定用地项目的测绘成果数据有详细的要求,根据分析测绘成果的DWG和SHP数据要求,研发了基于Auto CAD 2010的天津市核定用地成图与检查系统,实现了核定用地DWG数据和SHP数据的生产和检查。系统设计了XML文件记录成果文件标准、CAD实体标准和SHP字段标准,并且抽象出各类标准相关的数据结构,保证了生产和检查的统一,方便系统成果的规范化管理。

There are detailed requirements for Tianjin Verify Land surveying and mapping results. According to the analysis data requirements including DWG and SHP format developed mapping and checking system on the hase of Auto- CAD2010,implemented production and inspection for DWG data and SHP data. For this,a XMI, documentation record- ing file standard,CAD entity standard and SHP field standard is designed. Meanwhile, kinds of standards-related data structure are abstracted. This way ensnres the unity of the production and inspection, additional brings standardized man- agement results.
