In order to design a spatial index, the most important operations are: insertion, deletion and search. We focus on the deletion operation over the xBR-tree, a spatial data secondary memory structure that belongs to the Quad tree family. The algorithm of handling deletions is presented, taking into account that the deletion of a leaf item may cause entries deletions from internal nodes. The well-known merging technique is applied, to retain the efficiency of the xBR-tree.
