基于GIS的高速公路沿线设施管理信息查询系统的设计与实现

DESIGN AND IMPLEMENTATION OF INFORMATION QUERY SYSTEM FOR MANAGEMENT OF FACILITIES ALONG FREEWAY LINES BASED ON GIS

将GIS技术引入到高速公路沿线设施管理信息系统,实现沿线设备设施的可视化管理。并就如何在SuperMap平台下实现系统的查询功能进行了探讨。介绍了量子图形数据库,进行关键字段关联的方法实现图形与属性的互查,以及目标对象综合信息查询方法。利用SuperMap Objects的相关接口函数开发了高速公路沿线设施管理信息查询系统,使用户准确定位并查询感兴趣目标的空间信息、属性信息和综合信息,从而在宏观上把握高速公路上的设备设施,辅助相关人员进行管理和决策。

In this paper GIS technology is introduced to information system for the management of facilities along Freeway line for carrying out the visualization management on these facilities. A further discussion has been done on realizing the query function of the Super-Map- based system. Based on graphical database, the interactive queries between map and attribute by key field association and the query method of objects＇ synthetic information are also introduced in this paper. The information query system for themanagement of facilities along freeway line has been developed by using relative interface functions of SuperMap Objects, which makes customers sure to locate exactly and to en- quire the information of interested objects regarding space, attribute and integration. In general, this system can be of great use to assist pro- fessionals with decision-making and management by having a general idea of the facilities along Freeway line.
