m.extractlineseg - linear units extraction after segmentation
KEYWORDS
vector, segmentation, linear units, extraction
SYNOPSIS
m.extractlineseg m.extractlineseg help m.extractlineseginput=namepolygon=nameoutput=name [ID=string] [--overwrite] [--verbose] [--quiet]
Flags:
--overwrite
Allow output files to overwrite existing files
--verbose
Verbose module output
--quiet
Quiet module output
Parameters:
input=name
Input line vector name
polygon=name
Input segmented vector name
output=name
Output segmented line vector name
ID=string
Name of column for unique ID for the output layer (numerotation from 1); default is 'SELF_ID'
DESCRIPTION
m.extractlineseg script allows the user to extract linear units from segmented polygon input. The input polygon layer must be created by m.seg script. Input linear layer must be provided too.
NOTES
m.extractlineseg script creates a segmented linear layer from intersection between boundary nodes of the input segmented polygon layer and input linear layer. Even, if this script is able to work with complex geometry features, user should check the validity of the output linear layer produced ! Eventually, launch m.network script to verify vector geometry.
EXAMPLES
Creation of the seg_reach layer (with ident column name) from seg1 polygon layer and reachs linear layer
