摘要:: SuperMap Objects是全组件式GIS开发工具，它的开放性使用户能够比较容易地扩展它的功能。目前，基于组件式G1S已经成为地理信息系统软件发展的新潮流。Delphi是一个面向对象、功能丰富的可视化开发工具，在目前流行的众多开发工具中，其功能较为强大。文中结合SuperMap Objects和G1S的特点，给出了采用Delphi开发工具和SuperMap Objects控件技术来构建组件GIS的集成开发方法，探讨了在Delphi环境中地理信息系统组件的嵌入、地理信息系统基本功能如图形的放大、漫游以及信息查询等问题，进而为开发基于Delphi环境的组件式地理信息系统提供一点参考

Abstract:: SuperMap Objects is a development tool of GIS based on COM technology,and its opening makes users be able to extent its functions. At present,GIS based on components is a mainstream in GIS technology.Delphi is a programming language with sufficient functions, object oriented and visual. It is the more powerful one of popular programming languages at present. This article combined the peculiarity of SuperMap Objects and GIS, and put forward the integrate methods of COM GIS which using Delphi development tool and SuperMap component technology. The fundmental functions of GIS,such as build- in of GIS components,zoom,pan and informational search and so on have been discussed. The research in the paper gives a little referenesd bases for development of COM GIS based on Delphi
