Split a route into vertex-to-vertex segments

Source: R/slopes.R
route_to_segments.Rd

Splits a linestring with XYZ coordinates into individual 2-point segments, one per consecutive vertex pair. Useful for computing per-segment slopes with slope_xyz().

Usage

route_to_segments(route_xyz)

Arguments

route_xyz

An sf object with a single LINESTRING geometry with Z coordinates, as returned by elevation_add().

Value

An sf object with one LINESTRING feature per vertex-to-vertex segment.

Examples

route_xyz = elevation_add(lisbon_route, dem = dem_lisbon())
segs = route_to_segments(route_xyz)
segs$slope = slope_xyz(segs)
