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
