摘　　要：本论文面向"数字城市"的多源数据整合和分析,定义了空间数据立方体地理空间维、专题维和时间维分别包含的数据种类和内容,设计了它们的维和维层次数据结构;表述了维构成空间数据立方体的方法;确定了维的多维数组组织及存储策略;描述了空间度量的聚集概念,结合具体的图例讲述了点状、线状、面状空间度量的聚集过程。For multi-source data unity and analysis of 'digital city',the data category and content included by geospatial dimension,thematic dimension and time dimension of spatial data cube is defined in this paper firstly.Then their dimension structure and dimension hierarchy structure are designed.And the method that dimensions making up spatial data cube is expressed.Moreover,the organization and storage of multi-dimension array is determined.Finally,the aggregation concept of spatial measurement is defined,and the specific aggregation process on point,line,area spatial measurement combined with legend is expatiated.
