Abstract:Spatial OLAP systems aim to interactively analyze huge volumes of geo-referenced data. They allowdecision-makers to on-line explore and visualize warehoused spatial using pivot tables, graphical displaysand interactive maps. On the other hand, it has been recently shown that chorem maps represent an excellentgeovisualzation technique to summarize spatial phenomena. Therefore, in this paper we introduce aframework being capable to merge the interactive analysis capability of SOLAP systems and the potentialityof a chorem-based visual notation in terms of visual summary. We also propose a general architecture basedon standards to automatically extract and visualize chorems from SDWs according to our framework.
