create_cost_corridor: creates a cost corridor

In josephlewis/leastcostpath: Modelling Pathways and Movement Potential Within a Landscape

creates a cost corridor

Description

Combines and averages the accumulated cost surfaces from origin-to-destination and destination-to-origin to identify areas of preferential movement that takes into account both directions of movement

Usage

create_cost_corridor(x, origin, destination, rescale = FALSE)

Arguments

x	SpatRaster
origin	sf 'POINT' or 'MULTIPOINT', SpatVector, data.frame or matrix containing the origin coordinates. Only the first row of the supplied object is used as the origin.
destination	sf 'POINT' or 'MULTIPOINT', SpatVector, data.frame or matrix containing the destination coordinates. Only the first row of the supplied object is used as the destination.
rescale	logical. if TRUE, values scaled to between 0 and 1. FALSE (default)

Value

SpatRaster

Examples

r <- terra::rast(system.file("extdata/SICILY_1000m.tif", package="leastcostpath"))

slope_cs <- create_slope_cs(x = r, cost_function = "tobler", neighbours = 4)

locs <- sf::st_sf(geometry = sf::st_sfc(
sf::st_point(c(839769, 4199443)),
sf::st_point(c(1038608, 4100024)),
crs = terra::crs(r)))

cc <- create_cost_corridor(x = slope_cs, origin = locs[1,], destination = locs[2,], rescale = TRUE)
