z_value: Calculate summary values for 'Z' elevation attributes

In ITSLeeds/slopes: Calculate Slopes of Roads, Rivers and Trajectories

Calculate summary values for 'Z' elevation attributes

Description

The ⁠slope_z*()⁠ functions calculate summary values for the Z axis in sfc objects with XYZ geometries.

Usage

z_value(x)

z_start(x)

z_end(x)

z_mean(x)

z_max(x)

z_min(x)

z_elevation_change_start_end(x)

z_direction(x)

z_cumulative_difference(x)

Arguments

x	An sfc object with 'XYZ' coordinates

Value

A vector of values representing elevations associated with simple feature geometries that have elevations (XYZ coordinates).

Examples

x = slopes::lisbon_route_3d
x
z_value(x)[1:5]
xy = slopes::lisbon_route
try(z_value(xy)) # error message
z_start(x)
z_end(x)
z_direction(x)
z_elevation_change_start_end(x)
z_direction(x)
z_cumulative_difference(x)
