摘要
组件式地理信息系统(ComGIS)是GIS技术发展的潮流之一。对ESRI公司的ArcObjects和AreGIS Engine软件进行了简要的阐述,并结合宁波市甬江水域信息特点,在Visual C环境下开发出"污染源空间数据库系统",并对系统结构、数据准备和功能实现等作了阐述。所开发的系统具有可视化、查询统计、数据管理、空间分析、专题制图等功能。结果表明,嵌入式AreGIS Engine进行GIS应用开发时彻底脱离了AreGIS平台,提高了开发效率和开发的方便程度,缩短了开发周期,从而为用户提供了一个低成本、灵活定制的、轻量级的GIS应用选择。为开发环境决策支持系统提供了更为有力的技术平台。
Component geographic information system （ComGIS）is one of the developing points of GIS technology. The function of ArcObjects and ArcGIS Engine from ESRI Corp. was stated in this paper, and the pollution sources database system for Yongjiang water area in Ningbo City was developed in Visual C. The system structure, data preparation, and function realization of this database system were demonstrated. It was indicated that embedded-ArcGIS Engine is divorced from ArcGIS Platform and scores high in development efficiency and convenience, affording users a low-cost, special, and small-sized alternative. The system introduced in this paper provides primary decision support information for water pollution control and management in Ningbo City through data visualization,query, accounting, spatial analysis and thematic mapping. Because of the inherent flexibility of ArcGIS Engine, further decision support can be realized in combination with other information system through the interface preserved in advance.
