摘要
在车辆导航系统中，运用GIS技术能够直观形象地显示车辆实时运行状态等信息。本文探讨了如何在Visualc＋＋环境下，结合SuperMapObjects地理信息系统开发控件，构建车辆导航电子地图。阐述了使用SuperMapObjects控件进行GIS二次开发的一般方法和步骤，并给出了实例程序，实现了将空间数据进行地图显示以及放大、缩小、漫游、实时标注等GIS功能。
In the vehicle navigation system, the uses of GIS technology can directly and visually display the vehicles＇ real-time running states and other information. The paper discusses how to build the vehicle navigation electronic map with the help of the de- velopment controls of SuperMap Objects geographic information system in Visual C＋＋ environment. The authors elaborate the general methods and procedures of implementing GIS secondary development by using SuperMap Objects controls. The given example pro- grams realize the GIS functions of map displaying, amplifying, narrowing, roaming and real-time captioning with the spatial data.
