摘要
组件式GIS（ComGIS）是适应软件组件化潮流的新一代地理信息系统，本文介绍了ComGIS技术，并以ArcEngine控件为工具，结合需求介绍了基于组件技术的水库测绘信息查询系统的开发过程和功能实现，并对开发中的若干关键技术进行了程序说明。通过实际生产应用，证明该系统在数据管理、统计与直观显示等方面具有较好的实用价值。
ComGIS is a new generation GIS developed under the component modularization. This paper introduces the technique of ComGIS. Besides, this paper, using the control ArcEngine and considering the actual needs, presents the development course and function implementation of the Reservoir Surveying and Mapping Information Query System based on the COM technique, and instructs some key techniques employed in development with help of programs. The system is practical in managing data, doing the statistics and displaying visually, etc.
