【摘要】 城市基础地质数据是"数字城市"的基础性数据。为了建立科学合理的地质空间数据库,描述GeoDatabase空间数据模型和ArcSDE技术,在分析城市地质管理内容的基础上,以沈阳市的工程勘察数据为例,探讨GeoData-base的城市地质空间数据库的建立过程,并实现空间数据和属性数据的一体存储和管理;进而通过实例应用证明此数据库在应用系统开发中的实用性。更多还原

【Abstract】 The urban geology data is the base of Digital Cities.It is necessary to create effective geology GeoDatabase,and the aim of this paper is to create it.First GeoDatabase and ArcSDE were described in this paper.Then based on the analysis of the content of urban geology,this paper introduces the method of combining GeoDatabase and ArcSDE to design urban geology GeoDatabase using the data of Shenyang.And this GeoDatabase realizes the integrated memory of the attribute data and the spatial data.At last,this paper proves the GeoDatabase practicability by an example.更多还原
