Abstract--Decomposing a query window into maximal quadtree blocks is a fundamental problem in quadtree-based spatial database. Recently, Proietti presented the first optimal algorithm for solving this problem. Given a query window of size n_1 \times n_2, Proietti's algorithm takes O(n_l) time, where n_l = max(n_1, n_2). Based on a strip-splitting approach, this paper presents a newoptimal algorithm for solving the same problem. Experimental results reveal that our proposed algorithm is quite competitive with Proietti's algorithm.
