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)
