摘要
应用GIS建立城市防震减灾信息系统是一条减轻城市地震灾害的有效途径 ,而现有的城市防震减灾信息系统中防震减灾专业模型与GIS功能结合不够紧密 ,因此加强对地震灾害智能计算的研究十分重要。文章分析了城市防震减灾信息系统常用的二次开发方法 ,阐述了组件对象模型 (COM )技术及其在系统开发中的应用方法 。
Using GIS to develop urban seismic disaster mitigation information system is an effective way to reduce urban earthquake disaster. However, the professional earthquake hazard models do not integrate tightly with GIS functions in the existed systems, so it is very important to enhance the research on the intelligent calculation of earthquake hazard. In this paper, the redeveloping methods usually used in the urban seismic disaster mitigation system are analyzed; the component object model (COM) technology and its applied methods in the developing of the system is also expounded; the interfaces and functions of the system using the COM technology are formulated in detail.
