Description

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).

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.
