geo_cluster_dbscan() uint32_t * geo_cluster_dbscan ( const GSERIALIZED **  geoms, uint32_t  ngeoms, double  tolerance, int  minpoints, int *  count  ) Return an array of integers specifying the cluster number assigned to the input geometries using the DBSCAN algorithm contains a geometry. Parameters [in] geoms Geometries [in] ngeoms Number of elements in the input array [in] tolerance Tolerance [in] minpoints Minimum number of points [out] count Number of elements in the output array Note PostGIS function: ST_ClusterDBSCAN(PG_FUNCTION_ARGS)
