REVISITING THE OLAP INTERACTION TO COPE WITH SPATIAL DATA AND SPATIAL DATA ANALYSIS

摘要

In this paper we propose a new interface for spatial OLAP systems. Spatial data deals with data related to space and have a complex and specific nature bringing challenges to OLAP environments. Humans only understand spatial data through maps. We propose a new spatial OLAP environment compounded with the following elements: a map, a support table and a detail table. Those areas have synchronized granularity. We also extend OLAP operation to performed spatial analysis, for instance, spatial drill-down, spatial drill-up and spatial slice. We take special care in the spatial slice where we identify two main groups of operations: spatial-semantic slice and spatial-geometric slice.
