摘    要:目前普遍使用的基于图层的空间数据库模型存在许多问题。基于特征的空间数据库模型是一种新的空间数据存储模式,它在很大程度上代表了GIS的发展方向。采用超图数据模型分析、设计和描述土地利用特征在概念和逻辑层次的提取与定义,建立土地特征分类体系,进行基于特征的土地利用空间数据库建模。

关 键 词:GIS  空间数据库模型  基于特征  超图数据模型

Abstract:Layer based spatial database model is widely used now,which consequently causes some difficult problems.The feature based spatial database model is new spatial data storage mode,reflecting the development direction of GIS to great extent in future.In this paper,Hypergraph Based Data Model(HBDM) and object-oriented technology are applied in the process of building feature based spatial database model.In the process of modeling,the geographic features in land use management are abstracted,generalized and described.Through analyzing relations and sub-relations among different geographic features,the classification scheme of land use feature is established.And the conceptual and logical hierarchy definition of land use feature is presented.At last,feature based land use spatial database is designed and implemented.The result shows that the feature based spatial database model can express the land use information full and exactly,which supplies better support in managing and storing land use information.
Keywords:GIS  spatial database model  feature-based  Hypergraph Based Data Model(HBDM)
