create_cost_corridor: create_cost_corridor

Description

Creates a Cost Corridor raster object

Usage

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

Arguments

cost_surface

TransitionLayer object (gdistance package). Cost surface to be used in Cost Corridor calculation

origin

SpatialPoints. orgin location from which the Accumulated Cost is calculated. Only the first cell is taken into account.

destination

SpatialPoints. destination location from which the Accumulated Cost is calculated. Only the first cell is taken into account

rescale

if TRUE raster values scaled to between 0 and 1. Default is FALSE

Value

RasterLayer object

RasterLayer (raster package). The resultant object is the accumulated cost surface from origin-to-destination and destination-to-origin and can be used to identify areas of preferential movement in the landscape.

Details

Combines 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.

Examples

# NOT RUN {
r <- raster::raster(system.file('external/maungawhau.grd', package = 'gdistance'))
slope_cs <- create_slope_cs(r, cost_function = 'tobler', neighbours = 16)

loc1 = cbind(2667670, 6479000)
loc1 = sp::SpatialPoints(loc1)

loc2 = cbind(2667800, 6479400)
loc2 = sp::SpatialPoints(loc2)

cost_corridor <- create_cost_corridor(slope_cs, loc1, loc2, rescale = FALSE)
# }
