摘要
电子地图是矢量化、数字化的地图,是一个在计算机硬件、软件支持下,对有关地理分布数据进行信息处理的管理系统.分析研究GIS控件开发电子地图的方法和特点,给出了MapX开发电子地图的方法:首先使用Mapinfo来绘制地图,将要制作的城市电子地图分为不同图层导入到VB中,通过引入MapX控件,在VB中开发了长沙市电子地图,该地图具有查询、放大、缩小、漫游、测距等功能.
Electronic map is the vector, digital map, and exists in the digital form. It is a management system supported by the hardware and software of the computer, which copes with the geography distribution data. The method and advanced characteristics of developing electronic map with GIS component are studied. Based on MapX, the electronic map of Changsha city is developed by VB.
