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.
