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.

       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)
