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
21       calculations 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
25           algorithm 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
29           algorithm (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       -ds ds_name:
38           The name&path of the dataset to save the layer with resulting
39           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)
