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.
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'.
-ds ds_name:
The name&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.
The network to work with (path and name).
Dataset creation option (format specific)
Layer creation option (format specific)
Algorithm option (format specific)
