47 v.to.lines converts vector polygons (boundaries) to lines as well as
48 vector points to lines via triangulations.
49
51 v.to.lines is able to convert point data (via triangulation) and areas
52 to lines (via boundary to line conversion). This script is a wrapper
53 script to v.category, v.delaunay, and v.edit.
54
55 In order to convert an ordered list of coordinates (ASCII table with
56 x,y[,z] coordinates) into vector lines, use v.in.lines.

61 Area to line conversion
62 v.to.lines input=boundary_municp output=boundary_municp_lines
63
64 Point to line conversion
65 v.to.lines input=geodetic_pts output=geodetic_pts_lines
