DESCRIPTION
The gnmanalyse program provides analysing capabilities of geographical
networks in GDAL. The results of calculations are return in an OGRLayer
format or as a console text output if such layer is undefined. All cal-
culations are made considering the blocking state of features.
dijkstra <start_gfid> <end_gfid>
Calculates the best path between two points using Dijkstra algo-
rithm from start_gfid point to end_gfid point.
kpaths <start_gfid> <end_gfid>
Calculates K shortest paths between two points using Yen's algo-
rithm (which internally uses Dijkstra algorithm for single path
calculating) from start_gfid point to end_gfid point.
resource
Calculates the "resource distribution". The connected components
search is performed using breadth-first search and starting from
that features which are marked by rules as 'EMITTERS'.
-d <ds_name>
The name and path of the dataset to save the layer with result-
ing paths. Not need to be existed dataset.
-f <ds_format>
Define this to set the format of newly created dataset.
-l <layer_name>
The name of the resulting layer. If the layer exist already - it
will be rewritten.
<gnm_name>
The network to work with (path and name).
-dsco NAME=VALUE
Dataset creation option (format specific)
-lco NAME=VALUE
Layer creation option (format specific)
-alo NAME=VALUE
Algorithm option (format specific)
