摘要
通过对ARC/INFO的ODE(OpenDevelopmentEnvironment开放开发环境)中ActiveX控件对应的Carcedit类中成员的重新封装,添加了3个成员函数,更易于VC++和ARC/INFO的ODE集成开发。结合某市1∶50000的电子地图,开发了该市基本信息查询的地理信息系统,实现了大部分单位和学校、公交路线和街道的查询。管理员可以在原有基础上对地图的点和线以及内部属性数据进行编辑,同时还提供了基于街道中心线的最短路径分析。
From Re-encapsulating the ActiveX control of AR C/INFO and adding three member functions, it made integrating development of ARC/INFO and VC++ easier a nd more efficient. ARC/INFO integrating second time development environment is also introduced. Using 1∶50 000 scale electronic ma p of ChangChun, an ap plied GIS was developed. Using this system user can inquire about property of sc hools, some main buss stations and streets. Licensed users can edit school's pos ition in the map and its inside property data. Also the system provided shortest path analysis based on roads' centerline.
