中文摘要：

系统地论述了研究空间数据立方体的目的和意义，介绍了空间数据立方体的非空间维、空间维、数字度量、空间度量的基本概念和结构，描述了空间数据立方体的完整意思，设计出了空间数据立方体的概念模型即空间数据立方体的星型／雪片模型。最后，基于数学工具——代数系统，给出了空间数据立方体严格的数学定义。

英文摘要：

This paper states the purpose and significance to research spatial data cube, explains the relation between with spatial data cube and spatial data warehouse, introduces the concept and structure of nonspatial dimension, spatial dimension, digital measure and spatial measure, and designs conceptual model for spatial data cube, that is star/sonwflake model, At last, based on a mathematical tool： algebraic system, this paper gives definition of spatial data cube.
