.SH DESCRIPTION
.sp
The \fBgnmanalyse\fP 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.
.INDENT 0.0
.TP
.B dijkstra <start_gfid> <end_gfid>
Calculates the best path between two points using Dijkstra algorithm from start_gfid point to end_gfid point.
.UNINDENT
.INDENT 0.0
.TP
.B kpaths <start_gfid> <end_gfid>
Calculates K shortest paths between two points using Yen\(aqs algorithm (which internally uses Dijkstra algorithm for single path calculating) from start_gfid point to end_gfid point.
.UNINDENT
.INDENT 0.0
.TP
.B 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 \(aqEMITTERS\(aq.
.UNINDENT
.INDENT 0.0
.TP
.B \-d <ds_name>
The name and path of the dataset to save the layer with resulting paths. Not need to be existed dataset.
.UNINDENT
.INDENT 0.0
.TP
.B \-f <ds_format>
Define this to set the format of newly created dataset.
.UNINDENT
.INDENT 0.0
.TP
.B \-l <layer_name>
The name of the resulting layer. If the layer exist already \- it will be rewritten.
.UNINDENT
.INDENT 0.0
.TP
.B <gnm_name>
The network to work with (path and name).
.UNINDENT
