Organization and Storage of Multi-Dimension Array on Spatial Data Cube

ZOU Yi-jiang (College of Architectural Civil Engineering and Environment,Ningbo University,Ningbo 315211,China)  
Data classification and data content,respectively contained by geospatial dimension,thematic dimension and time dimension of spatial data cube,are defined in this paper.The geospatial dimension,thematic dimension,time dimension structure and their dimension hiberarchy structure are described.The method that geospatial dimension,thematic dimension,time dimension together make up spatial data cube is expressed by conceptual and physical mode.Also,the data organization based on multi-dimension array and data storage based on data file and virtual memory on geospatial dimension data,thematic dimension data and time dimension data are explained.The associational operation between records in multi-dimension array and compressing method of multi-dimension array are stated.
