DESCRIPTION

v.split splits vector lines into shorter segments using a maximal distance between nodes. The resulting length of all segments is expected to be equal and not higher than the given length parameter.

EXAMPLES

The examples are based on the North Carolina sample data location.

Example 1: Inserting nodes to railroad map

# extract data for this example
v.extract railroads out=myrr cats=1

# show line, category, direction (to find the beginning)
d.vect myrr disp=shape,cat,dir

# insert nodes at a distance not longer than 1000m
v.split myrr out=mrr_split length=1000
d.vect myrr_split disp=shape,topo
Note: In case the data is not a polyline, build polylines in second step, eg.: 
# join segments into polyline
v.build.polylines myrr out=myrr_poly
v.category myrr_pol out=myrailroads option=add

Example 2: Inserting vertices to railroad map

Note: first run the two steps from example 1. 
# insert vertices at a distance not longer than 1000m
v.split -n myrr out=myrr_split length=1000
d.vect myrr_split disp=shape,topo
