基于本体的地理空间信息集成框架与实现

Geo-Spatial Information Integration Framework and Realization on Ontology

论述了地理本体的基本概念、结构,介绍了地理本体的建模方法,提出了基于地理本体的空间数据集成框架,包括构建地理本体、数据预处理、概念映射、数据映射和数据抽取与转换5个步骤;设计了基于本体的空间数据集成方案,以数字地形图数据、海图数据向标准本体的集成为例对方案进行验证试验,并取得了初步成果。

Basic concepts, components and construction methods of geo-ontology were briefly introduced in this thesis. Integration framework based on geo-ontology was presented, including geo-ontology constructing, data preprocessing, conception mapping, data mapping, data taking out and conversion. Integration project based on geo-ontology was designed. At last, the design project was validated by integrating digital relief map and chart to standard geo-ontology.
