The only difference is that the partitioning step in SpatialHadoop uses a spatial partitioning rather than the default non-spatial partitioning as depicted in Fig. 5, where adjacent polygons are assigned to the same machine.

WebUses a sweep line algorithm to construct the union, intersection, or difference of sets of polygons. In computational geometry, polygon triangulation is the partition of a polygonal area (simple polygon) P into a set of triangles, i.e., finding a set of triangles with pairwise non-intersecting interiors whose union is P. Triangulations may be viewed as special cases of planar straight-line graphs. When there are no holes or added points, triangulations form maximal outerpla…
