摘要
设计主要用GIS组件MapX技术,运用VB可视化开发语言为工具,以ACCESS数据库为支持建立的基础地理信息系统。系统通过乌鲁木齐市公交线路查询系统应用实例,详细讨论数据库的设计、信息查询及数据访问等功能,实现了基础地理信息系统的基本功能,如图层的控制、空间数据和属性数据的双向查询及地图的放大、缩小、漫游等。系统实现结果表明,MapX作为一个具有强大地图功能的ActiveX控件,可以灵活、高效地实现地理信息系统的应用。
Abstract A basic geographic iniormation system was established by using GI5 components, MapX technique, VB visual programming language as too]. With Urumqi bus lines enquiries system as example, database design, information enquiries and data access were discussed in detail. The basic functions were realized, such as layer control, amplification, narrow, roaming of map, bidirectional query of spatial data and attribute data. The results showed that ActiveX control can flexibly, efficiently implement the application of geographic information system.
