Spatial DataWarehouse (SDW) and Spatial OLAP (SOLAP) systems integrate spatial anal- ysis and geovisualization tools offered by Geographic Information Systems to OLAP function- alities. Few works investigate geovisualization issues in SOLAP systems, and no works inves- tigate tools for readable SOLAP cartographic displays. Therefore, decision-makers manually make the configuration of the cartographic visualization in existing SOLAP tools. Therefore, we present in this paper a new geovisualization methodology for SOLAP queries that yields readable maps.
