GNMANALYSE(1) GDAL GNMANALYSE(1) NAME gnmanalyse - Analyses networks SYNOPSIS Usage: 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 net- works 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 calculat- ing) 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) RETURN STATUS CODE The program returns status code 0 in case of success, and non-zero in case of error (non-blocking errors emitted as warnings are considered as a suc- cessful execution).
