Options: delaunay
Default: delaunay converts vector polygons (boundaries) to lines as well as vector points to lines via triangulations. 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

The examples are for the North Carolina sample dataset location: input=boundary_municp output=boundary_municp_lines input=geodetic_pts output=geodetic_pts_lines
