Spatial Data Warehouses (SDWs) enable the simultaneous processing of multidimensional queries and spatial analysis. In the literature, little attention has been devoted to the development of benchmarks for analyzing the performance of query processing over SDWs. In this paper, we propose a novel benchmark, called Spatial SSB, designed specifically to perform controlled experimental performance evaluation of SDWs environments. The Spatial SSB proposes a non-redundant SDW schema and controls: the generation of data, the query selectivity and the data distribution in the extent. In addition, the Spatial SSB provides the increase of the data volume, varies the complexity of spatial objects geometries, and generates a certain number of objects that intersect an ad hoc spatial query window.
