Abstract

The star or snowflake type multi-dimension spatial data warehouse is based on the spatial facts as core and geological attributes as dimensions. A method for constructing spatial factual table based on the spatial relations of data is proposed. The construction of spatial facts and the relations analysis of spatial facts is based on the geological attribute dimension and vexel. In order to express the spatial multi-dimension data, an octree subsection vexel model is given. The expression of multi-dimension data and spatial integration of the multilevel vexel geological bodies and geological fields devision based on Morton decimal coding are implemented.
