摘要
针对复杂的道路交通事故信息,利用MapInfo公司的组件式控件MapX5.0,在PowerBuilder8.0开发环境下,使用SQLServer2005作为系统后台属性数据库,研究路段采用高分辨率的遥感数据为地图背景,设计开发了城市道路交通事故信息系统。该系统具有城市道路交通信息与道路交通事故信息的查询、分析和统计功能,使道路交通事故信息查询更迅速、直观。实际开发表明,PowerBuilder与地图控件MapX结合开发GIS应用系统,不仅开发过程简单、开发速度快,而且能充分发挥PowerBuilder快速高效管理、访问MapX空间数据库的优势。
Under PowerBuilder8.0 environment, with powerful GIS component MapX5. 0 and background attribute database SQL Server 2005, and taking high resolution RS data as Map background, a city traffic accident information system is developed. The System has many functions, such as query, analyse and statistic for traffic and accident information. It is easy and intuitive to query useful information. Experimental result shows that, based on PowerBuilder and MapX, it is not only easy and fast to develo PGIS application, but also exerts sufficiently the advantage of managing and accessing the MapX space database of PowerBuilder.
