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.
- 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
vertexes and gfid_con is edge (gfid_con can be -1, so the system edge will
be inserted).
- -c
cost -ic inv_cost
-dir dir:
- Manually assign the following values: the cost (weight), inverse cost and
direction of the edge (optional).
- 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.
