NAME

v.to.lines - Converts vector polygons or points to lines.

KEYWORDS

vector, geometry, area, line, point

SYNOPSIS

v.to.lines
v.to.lines --help
v.to.lines input=name output=name [method=string] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:


Allow output files to overwrite existing files

Print usage summary

Verbose module output

Quiet module output

Force launching GUI dialog

Parameters:


Name of input vector map
Or data source for direct OGR access

Name for output vector map

Method used for point interpolation
Options: delaunay
Default: delaunay

DESCRIPTION

v.to.lines converts vector polygons (boundaries) to lines as well as vector points to lines via triangulations.

NOTES

v.to.lines is able to convert point data (via triangulation) and areas to lines (via boundary to line conversion). This script is a wrapper script to v.category, v.delaunay, and v.edit.

In order to convert an ordered list of coordinates (ASCII table with x,y[,z] coordinates) into vector lines, use v.in.lines.

EXAMPLES

The examples are for the North Carolina sample dataset location:

Area to line conversion

v.to.lines input=boundary_municp output=boundary_municp_lines

Point to line conversion

v.to.lines input=geodetic_pts output=geodetic_pts_lines
