Technological Frame of Spatial Data Cube
空间数据立方体的技术框架*

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.
