gnmanalyse - Analyses networks
SYNOPSIS
gnmanalyse [--help] [--help-general] [-q] [-quiet] [--long-usage] [dijkstra <start_gfid> <end_gfid [-alo <NAME>=<VALUE>]...] [kpaths <start_gfid> <end_gfid> <k> [-alo <NAME>=<VALUE>]...] [resource [-alo <NAME>=<VALUE>]...] [-ds <ds_name>][-f <ds_format>][-l <layer_name>] [-dsco <NAME>=<VALUE>]... [-lco <NAME>=<VALUE>]... <gnm_name>
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)
