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

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
