DESCRIPTION
The gnmmanage program can perform various managing operations on geo-
graphical networks in GDAL. In addition to creating and deleting net-
works this includes capabilities of managing network's features, topol-
ogy 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 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 fea-
tures 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.
