line_segmentize: Segments a LineString into n equal length LineStrings

Description

Given a LineString, segment it into n equal length LineStrings. The n LineStrings are provided as a MultiLineString which can be expanded using expand_geoms() and consequently flattened using flatten_geoms() if desired.

Usage

line_segmentize(x, n)
line_segmentize_haversine(x, n)

Value

A vector of class rs_MULTILINESTRING

Arguments

x

and object of class rs_LINESTRING

n

an integer vector determining the number of equal length LineStrings to create

Details

line_segmentize() will segment a LineString using a Euclidean length calculation. line_segmentize_haversine() will use a Haversine length calculation instead. If you have geometries in a geographic cooridnate system such as EPSG:4326 use the Haversine variant. Otherwise, prefer the euclidean variant.

Examples

x <- geom_linestring(1:10, runif(10, -1, 1))

segs <- line_segmentize(x, 3)

flatten_geoms(
  expand_geoms(segs)
)
