Overview
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:
Area to line conversion
v.to.lines input=boundary_municp output=boundary_municp_linesPoint to line conversion
v.to.lines input=geodetic_pts output=geodetic_pts_linesSource code
