## 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)

## 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 successful execution).
