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:
- --overwrite
- Allow output files to overwrite existing files
- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
Parameters:
- input=name [required]
- Name of input vector map
- Or data source for direct OGR access
- output=name [required]
- Name for output vector map
- method=string
- Method used for point interpolation
- Options: delaunay
- Default: delaunay
v.to.lines converts vector polygons (boundaries) to lines as well
as vector points to lines via triangulations.
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.
The examples are for the North Carolina sample dataset location:
v.to.lines input=boundary_municp output=boundary_municp_lines
v.to.lines input=geodetic_pts output=geodetic_pts_lines
v.category,
v.delaunay,
v.edit,
v.in.lines,
v.to.points,
v.type
