Abstract The MMP (Minimum Maximum Points) filter algorithm is a highly-efficient filter algorithm for the spatial data in the object-relational spatial database. The description and the application result analysis of the MMP algorithm demonstrate the advantages of the MMP algorithm in the retrieval of mass volume of spatial data, i.e., the speed of the MMP algorithm is at least scores of times higher than that of the function operation.
