摘要
分析了MapObjects组件的特点和功能,介绍了在VisualC++环境下基于MapObjects组件开发地理信息系统的方法,并结合一个车辆定位监控系统探讨了图层处理、实时跟踪、地理要素拾取、图层标注、交互式提示等功能的具体实现,给出了该系统的设计原理、组成、功能、主要技术特点及其应用。实践表明,系统编程体现了地图组件处理地理信息的优势和面向对象编程的灵活性。
This paper Analyses main features and functions of MapObjeets control,and introduces principles and methods of developing GIS based on MapObjects control in Visual C++.A case study is given to illustrate how to implement the functions of layers control,real-time tracking,identifying features,labeling map layers,interactive map tips and so on.The structure,functions.main technical features and their implementation principles of a vehicle positioning and monitoring system are discussed.Experiences show that the system indicates the advantage of Map Controls in developing geographic information system and the feasibility of object-oriented programming.
