The invention discloses a parallel POI (Points of Interest) simplification oriented task splitting and
distribution method which particularly comprises the following steps that (1), POI data is read; (2), the POI number Nf of target data is computed; (3), the number N of computation nodes of parallel computation is set; (4), a parallel POI simplification oriented data
granularity model is established; (5) a Hi set (which represents a set of C (i, j) of a circle taking a point i as a circle center and C (i, j) as a
radius internally tangent to a circle taking a point j as a circle center and C (i, j) as a
radius) of each POI point is subjected to the parallel computation; (6), a relation between the number Nr of the residual points and the POI number Nf of the target data is judged, if Nr is greater than Nf, Step (7) is executed, and if Nr is less than Nf, the step is completed; (7), Hi of the POI point in each computation node is subjected to
parallel sorting; (8), a minimum value Gc of the global Hi is subjected to parallel solving; and (9), the POI point corresponding to the minimum value Gc is selected, Step (6) is executed, and Step (6) to Step (9) are repeated till completion. The method has the characteristics of simplification,
automation and intelligentization, can improve the efficiency of parallel POI simplification, and can guarantee the accuracy of the parallel POI simplification.
