基于Geodatabase和ArcSDE的城市地质空间数据库设计

Design of City Geology Space Database Based on Geodatabase and ArcSDE

城市基础地质数据是"数字城市"的基础性数据。随着地质资料数据的急剧增多,迫切需要建立有效的地质空间数据库。为建立科学合理的地质空间数据库,描述了Geodatabase空间数据模型和ArcSDE技术,以沈阳市的工程勘察数据为例,在分析城市地质管理内容的基础上,探讨了城市地质Geodatabase空间数据库的建立过程,实现了空间数据和属性数据的集成化一体存储和管理,为实现城市基础地质数据的科学管理和应用提供了保障。

The building of digital cities should be based on urban geology data. It is necessary to create an effective geology Geodatabase, which is the aim of the present paper. First, a decription of Geodatabase and ArcSDE is made, then based on the analysis of urban geology, a method of combining Geodatabase and ArcSDE is proposed to build the urban geology Geodatabase using the data of Shenyang. This Geodatabase inplements the integrated storage of the attribute data and the spatial data, and ensures the easy management and use of the urban geology data.
