摘　　要：本文针对湖南省矢量空间数据来源复杂、格式不一等问题,建立了一套多源矢量空间数据集成框架。该框架以基础地理信息数据分类分层体系为依据,从数据空间、属性、格式等方面制定数据集成规则,实现多源异构矢量空间数据集成。建立的多源矢量空间数据集成框架为湖南省地理空间数据交换共享数据库构建提供了重要支撑。Heterogeneous geospatial vector data obtained from multi-sources occur to large discrepancies on precisions,scales,spatial relationships and semantic representations,which leads to the contradiction of duplications in data collection and difficulties in information sharing.On that account,this study aims to develop a framework for integrating multi-source heterogeneous geospatial vector data in Hunan province.In this framework,the feature classification and codes of fundamental geographic information is first used as the standard classification system of geospatial vector data.Then,the integration rules are defined for data format,spatial and attribute information.The prosed geospatial vector data integration framework has been applied to construct geospatial vector data exchange and sharing database in Hunan province.
