摘要
提出基于MapObjects组件式GIS开发模式开发城市道路查询系统。系统选用目前被公认为最优秀的Shapefile文件格式的数据作为分析数据,对道路查询系统的功能和数据库进行了详细设计。本系统除实现道路基本查询、检索等基本功能外,针对目前网络分析问题研究较少的现状,还进行了一定的网络分析,进行了最优路径规划算法的实现。同时,系统具有一定的可扩展性。
The article proposed the urban road inquiry system based on the MapObjects module of ComGIS development.The system selects the most outstanding document format data-Shapefile to analysis data.And carried on the detailed design to the system function and database design.Besides some basic functions,such as inquire function and analyze function,the system can also do some net analyze,the best route algorithm is also achieved in the system.Meanwhile,the system has expandable characteristic.
