Efficient evaluation of spatial join is an important issue in spatial databases. The traditional evaluation strategy is to perform a join of “minimum bounding rectangles” (mbr) of the spatial objects (mbr-filter) and evaluate the actual join of the objects using the results of the join on approximations. Improvements to add additional filtering using more accurate approximations were also considered. In the present paper, we develop efficient algorithms for evaluating joins of “trapezoids… CONTINUE READING
