NAME

       v.split  - Split lines to shorter segments.

KEYWORDS

       vector, geometry

SYNOPSIS

       v.split
       v.split help
       v.split   input=name   output=name    [length=float]    [vertices=integer]    [--overwrite]   [--verbose]
       [--quiet]

   Flags:
       --overwrite
           Allow output files to overwrite existing files

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       input=name
           Name of input vector map

       output=name
           Name for output vector map

       length=float
           Maximum segment length

       vertices=integer
           Maximum number of vertices in segment

DESCRIPTION

       v.split split vector lines into shorter segments using a maximal distance between nodes.

EXAMPLE

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