humanscape: Compute Energy Landscapes for Walking People

Description

This is the main function to compute energy landscapes from a digital elevation model, body mass of a person, and walking speed from Looney et al. (2019).

Usage

humanscape(dem, m, v = 1.39, unit = "joule", neigh = 8)

Value

EnergyScape raster.

Arguments

dem

raster file of the digital elevation model, either a raster or a full path location of the file.

m

species body mass (kg).

v

walking speed (m/s).

unit

if joules ('joule') or kilocalories ('kcal').

neigh

number of neighbor cells that are connected together.
