DESCRIPTION

18       The  gnmanalyse program provides analysing capabilities of geographical
19       networks in GDAL. The results of calculations are return in an OGRLayer
20       format or as a console text output if such layer is undefined. All cal‐
21       culations are made considering the blocking state of features.
22
23       dijkstra <start_gfid> <end_gfid>
24              Calculates the best path between two points using Dijkstra algo‐
25              rithm from start_gfid point to end_gfid point.
26
27       kpaths <start_gfid> <end_gfid>
28              Calculates K shortest paths between two points using Yen's algo‐
29              rithm (which internally uses Dijkstra algorithm for single  path
30              calculating) from start_gfid point to end_gfid point.
31
32       resource
33              Calculates the "resource distribution". The connected components
34              search is performed using breadth-first search and starting from
35              that features which are marked by rules as 'EMITTERS'.
36
37       -d <ds_name>
38              The  name and path of the dataset to save the layer with result‐
39              ing paths. Not need to be existed dataset.
40
41       -f <ds_format>
42              Define this to set the format of newly created dataset.
43
44       -l <layer_name>
45              The name of the resulting layer. If the layer exist already - it
46              will be rewritten.
47
48       <gnm_name>
49              The network to work with (path and name).
50
51       -dsco NAME=VALUE
52              Dataset creation option (format specific)
53
54       -lco NAME=VALUE
55              Layer creation option (format specific)
56
57       -alo NAME=VALUE
58              Algorithm option (format specific)
