摘要
从城市公交查询系统建立的必要性出发,研究了基于组件式G IS的公交查询系统的设计,探讨了以换乘次数最少为目标的公交查询系统的实现方案。本系统选用G IS组件M apOb jects作为地理信息系统二次开发组件,通用语言V isual Basic 6.0作为开发工具,M icrosoftAccess 2000作为后台数据库,开发城市公交查询系统,实现了地图的放大、缩小、漫游等G IS软件的基本功能,以及公交换乘方案和地名的查询等空间查询功能。
Based on the necessity of urban public traffic inquiry system, this article studies the design of the system based on component GIS, discusses the realization project of the public traffic inquiry system aiming at the least times of bus transfer. The system chooses MapObjects to be component of GIS secondary component, current program language Visual Basic 6.0 as develop tool, Microsoft Access 2000 as background database, developed urban road and traffic inquiry system. It realized basic skills of GIS software such as zoom in, zoom out and ramble, and special search skills, namely, way of bus transfer and search of place names.
