hf_velocity: General hiking function for velocity

In kbvernon/rHike: Functions for Computing Hiking Efficiency and Velocity

Description

A convenience wrapper for generating a velocity (distance per unit time) raster based on various hiking functions.

Usage

hf_velocity(x, hf = "tobler", ...)

Arguments

x	A RasterLayer with slope values, assumed to be in degrees.
hf	Character The hiking function with which to compute velocity, either "tobler" (default) or "campbell."
...	Arguments to be passed to individual hiking functions.

Value

A RasterLayer of velocity values in km/hr.

Examples

## Not run: 

library(raster)

dem <- raster(system.file("extdata/slc.tif", package = "rHike"))

slope <- hf_slope(dem)

tobler <- hf_velocity(slope, hf = "tobler", on.path = TRUE)
campbell <- hf_velocity(slope, hf = "campbell", decile = 30)

plot(stack(tobler, campbell))


## End(Not run)
