       The  gnmmanage  program  can  perform  various  managing  operations on geographical networks in GDAL. In
       addition to creating and deleting networks this includes capabilities  of  managing  network's  features,
       topology and rules.

       --help Show this help message and exit

       --help-general
              Gives a brief usage message for the generic GDAL commandline options and exit.

       -info  Different  information  about  network: system and class layers, network metadata, network spatial
              reference.

       create Create network.

              -f<format_name>
                     Output file format name.

              -t_srs<srs_name>
                     Spatial reference input.

              -dsco<NAME>=<VALUE>
                     Network creation option set as pair name=value.

       import<src_dataset_name>
              Import layer with dataset name to copy.

              -l<layer_name>
                     Layer name in dataset. If unset, 0 layer is copied.

       connect<gfid_src><gfid_tgt><gfid_con>
              Make a topological connection, where the gfid_src and gfid_tgt are vertices and gfid_con  is  edge
              (gfid_con can be -1, so the system edge will be inserted).

              Manually assign the following values:

              -c<cost>
                     Cost / weight

              -ic<invcost>
                     Inverse cost

              -dir<dir>
                     Direction of the edge.

       disconnect<gfid_src><gfid_tgt><gfid_con>
              Removes the connection from the graph.

       rule<rule_str>
              Creates a rule in the network by the given rule_str string.

       autoconnect<tolerance>
              Create  topology  automatically  with the given double tolerance and layer names. In no layer name
              provided all layers of network will be used.

       delete Delete network.

       change Change blocking state of network edges or vertices.

              -bl<gfid>
                     Block feature before the main operation. Blocking features are saved in the special layer.

              -unbl<gfid>
                     Unblock feature before the main operation.

              -unblall
                     Unblock all blocked features before the main operation.

       <gnm_name>
              The network to work with (path and name).

       <layer>
              The network layer name.
