摘要
空间数据库是GIS的核心与关键,而数据模型是空间数据库的前提与基础。因此,设计并创建空间数据库数据模型显得尤为重要。研究了基于空间数据库的概念模型,逻辑模型,定义了构成数字地质图各要素间的逻辑关系,重点将ArcGIS的CASE工具与Visio 2003相结合详细构建跨越国境巴尔喀什-准噶尔地区地质图的物理模型,合理地将空间数据和属性数据有效地融合在一起,完成了面向对象数字地质图数据模型的建立。
The spatial database is both the core and the key to GIS while the data model is the premise and the foundation for a spatial database. Therefore, it is especially important to design and establish the data model for spatial database. The paper studies the conceptual model, logistic model based on the spatial databases, defines the logical relationships between the elements composing the digital geological map, and describes the detailed construction of the physical model of the cross-border geological map of Balkhash-Junggar regions by a combined use of 2003 Visio and ArcGIS CASE tool, by which the spatial data and attribute data are effectively converged and the object-oriented digital geological map data model is established.
