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)
