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)
