Spatial joins are join operations that involve spatial data types and operators. Spatial access methods are often used to speed up the computation of spatial joins. This paper addresses the issue of benchmarking spatial join operations. For this purpose, we first present a WWW-based tool to...

Most data collected in statistics and science is still stored in simple flat files, usually data matrices with rows identified by a case identifier (case_id), columns corresponding to attributes (variables), and numerical data types for the elements of each matrix due to coding of all attributes...
