We introduce an improved method to split overflowed nodes of R-tree spatial index called the Corner Based Splitting (CBS) algorithm. Good splits produce an efficient R-tree which has minimal height, overlap and coverage in each node. The CBS algorithm selects the splitting axis that produces the most even split according to the number of objects, using the distance from each object centre to the nearest node's MBR corner. Experiments performed using both synthetic and real data files showed obvious performance improvement. The improvement percentage over the Quad algorithm reached 23%, while the improvement percentage over the NR algorithm reached 37%.
