This recipe uses the Sample Data network.

The purpose of this recipe is to compare a not nodded network with a nodded network.

    SELECT pgr_createTopology('edge_table', 0.001);
    SELECT pgr_analyzegraph('edge_table', 0.001);
    SELECT pgr_nodeNetwork('edge_table', 0.001);
    SELECT pgr_createTopology('edge_table_noded', 0.001);
    SELECT pgr_analyzegraph('edge_table_noded', 0.001);
