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 calculations are made considering the blocking state
of features.
--help Show this help message and exit
--help-general Gives a brief usage message for the generic GDAL commandline
options and exit.
dijkstra <start_gfid> <end_gfid> Calculates the best path between two points using Dijkstra
algorithm from start_gfid point to end_gfid point.
kpaths <start_gfid> <end_gfid> Calculates K shortest paths between two points using Yen's
algorithm (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
resulting 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)
