摘要
分析国内外城市地理信息系统技术建设数字城市存在的问题 ,依据数字城市建设要求 ,从数字化角度分析城市多源信息的特点 ,针对基于域和对象的空间信息模型 ,运用面向对象方法体系 ,构造一种能够集成域和对象模型的空间数据复合模型 ,使其能满足数字城市建设对城市多源动态信息的一体化管理。
The shortage existing in the inheritance of urban geographic information system technology in digital city construction at home and abroad is analyzed and summarized. The features of city multi-source information is analyzed from digital aspect according to the need of digital city construction. Aimed at field-based model and object-based model in spatial information, applying object-oriented method, a synthetic model is constructed which can integrate field-based model and object-based model. The synthetic model can meet the need of integrated management, composition and collection of city multi-source dynamic information in digital city construction.
