OLE Automation在MapInfo地理信息系统地图集成中的应用

Application of OLE automation in mapInfo integrated mapping

配电信息管理是电力行业应用GIS的主要领域 ,需要充分利用配电网络的地理信息 ,以实现电力的合理调配。Microsoft公司推出的OLEAutomation技术允许应用程序访问在另一个应用程序中实现的一些可编程对象 ,为在配电信息管理中实现地图集成提供了有效的方法。MapInfo是美国MapInfo公司推出的基于桌面的地理信息系统 ,允许Delphi,VB ,C ++等开发工具将其提供的对象进行编程。结合实例详细论述了在Delphi环境下 ,利用OLEAutomation技术进行基于MapInfo地图集成的方法。该方法在实践中取得了很好的效果。

Power Distribution Information Management is the main application field of GIS in Power Indusrty,and it must take full advantage of geographic information of Power Distribution Network to realize the reasonable Power Distribution.OLE Automation technology offered by Microsoft Corp.allows one application to access the programable objects provided by the other application,and gives a solution to integrated mapping in Power Distribution Information Management.MapInfo is the GIS desk top product provided by MapInfo Corp.in USA,and allows Delphi,VB,C++ to use its programable objects.With an example the paper discusses the method using OLE Automation to realize integrated mapping based on MapInfo in Delphi environment.The method is effective in practice.
