%description
Provides the facility to calculate non-isotropic accumulated cost
surfaces, least-cost paths, least-cost corridors, least-cost networks,
ranked alternative paths, cost allocation and cost boundaries, using a
number of human-movement-related cost functions that can be selected by
the user. The terrain factor can be set as a single value or vary across
the landscape via a raster of terrain factors or terrain classes. The
package is built around a compute-once design: a single cost surface
object is created first and then reused by every analysis function,
avoiding redundant computation. Visualisation is fully decoupled from
computation and is provided through 'ggplot2' methods that can be invoked,
customised, and re-invoked at any time without re-running any analysis. It
just requires a Digital Terrain Model, a start location and (optionally)
destination locations. See Alberti (2019)
<doi:10.1016/j.softx.2019.100331>.
