DESCRIPTION

34       v.split split vector lines into shorter segments using a  maximal  dis‐
35       tance between nodes.

EXAMPLE

38       Spearfish location:
39       # insert kilometric nodes to railroad map:
40       v.extract railroads out=myrr list=1
41       # join segments into polyline
42       v.build.polylines myrr out=myrr_pol
43       v.category myrr out=myrailroads option=add
44       # show line, category, direction (to find the beginning)
45       d.vect myrailroads disp=shape,cat,dir
46       # insert nodes at 1000m distance (max)
47       v.split railroads out=myrailroads_split length=1000
48       d.vect myrailroads_split disp=shape,topo
