DESCRIPTION

41       v.split split vector lines into shorter segments using a  maximal  dis‐
42       tance between nodes.
43

EXAMPLE

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