摘要
通过GIS应用中叠加分析功能的二次开发,介绍了ArcInfo结合VisualBasic进行二次开发的方法,阐述了ArcObjects包含的核心原理和技术,并结合COM技术剖析了ArcInfo、扩展功能(d11)和ArcObjects之间的通讯机制。在叠加分析功能的开发实践经验基础上,简单介绍了一些ArcObjects类的使用。实践经验证明,使用VB扩展ArcInfo功能,可以节省时间和精力,两者的结合充分发挥了各自的优势,在经费投入和进度控制上都能起到事半功倍的作用。
By the secondary development of overlap function in the application of GIS, this paper mainly introduces the development methods with the combination of ArcInfo and Visual Basic and the core principle and technolgoy contained in ArcObjects, and analyzes the communication mechanism among ArcInfo、 expanded function and ArcObjcets with COM technology. The paper describes some usages of ArcObjects Class on the basis of the secondary development of overlap function. The experience of practice prove that expansion in ArcInfo function with Visual Basic may retrench time and vigor of developer and combination of them can completely perform advantage of each, which also can promote success in devotion of outlay and control of schedule.
