Range Aggregate Processing in Spatial Databases

Traditional research in spatial databases often aims at the range query, which retrieves the data objects lying inside (or intersecting) a multidimensional hyper-rectangle.In many scenarios (e.g., statistical analysis, data warehouses, etc.), however, users are interested only in summarized information about such objects, instead of their individual properties.
