The conceptual design on spatial data cube
Zou Yi-jiang · 2012
This paper states the purpose and significance to research spatial data cube, and explains relationship between with spatial data cube and spatial data warehouse, and introduces the concept and structure of nonspatial dimension, spatial dimension, digital measure and spatial measure, and designs conceptual model for spatial data cube, i.e. extended star/sonwflake model. At last, based on mathematical tool - algebraic system, this paper gives algebraic definition of spatial data cube.
