In skgrange/gissr: Tools To Make Working With R and Spatial Data Easier

Function to split spatial lines into segments with fixed lengths.

Description

sp_segment_lines has been pulled from another package which can be found here,

Usage

sp_segment_lines(sp, length, features = FALSE)

Arguments

sp	Spatial line object.
length	Length for the split segments. This is in the units of sp's projection system.
features	Should the function be applied to all features in sp separately?

Value

SpatialLinesDataFrame with one id variable.
