摘要
组件式地理信息系统是目前GIS软件技术发展的主流。分析了MapInfo公司推出的MapX组件和美国环境系统研究所推出的MapObjects组件的特点和功能,介绍了在Visual C++环境下开发二者的差异,探讨了在控件初始化、图层操作、动态目标实时跟踪、通用地图工具等具体功能实现上的差别,并给出了实例说明。最后,总结了MapX与MapObjects各自的开发优势和缺陷。
In recent years the trend of components GIS has become more and more popular in developing GIS software. Analyses main features and functions of MapX produced by MapInfo Corporation and MapObjects produced by environmental systems research institute, and compares the differences of developing GIS applications based on them in Visual C＋＋. Code samples are also given to illustrate how to implement the functions of component initialization, layers control, real-time tracking, common map tools and so on. After comparing their advantages and shortcoming, the general principles is put forward to help readers to determine which GIS component should be chosen in different conditions.
