leastcostpath (version 1.2.1)

create_lcp_density: create_lcp_density

Description

Creates a cumulative least cost path raster

Usage

create_lcp_density(lcps, raster, rescale = FALSE)

Arguments

lcps

SpatialLines or SpatialLinesDataFrame. Least Cost Paths

raster

RasterLayer (raster package). This is used to derive the resolution, extent, and spatial reference system to be used when calculating the cumulative least cost path raster

rescale

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

Value

RasterLayer (raster package). The resultant object is the cumulatively combined Least Cost Paths. This identifies routes of preferential movement within the landscape.

Details

Cumulatively combines Least Cost Paths in order to identify routes of preferential movement within the landscape.

Examples

# NOT RUN {
r <- raster::raster(nrow=50, ncol=50,  xmn=0, xmx=50, ymn=0, ymx=50, crs='+proj=utm')

r[] <- stats::runif(1:length(r))

slope_cs <- create_slope_cs(r, cost_function = 'tobler')

x1 <- c(seq(1,10), seq(11,25), seq(26,30))
y1 <- c(seq(1,10), seq(11,25), seq(26,30))
line1 <- sp::SpatialLines(list(sp::Lines(sp::Line(cbind(x1,y1)), ID='a')))

x2 <- c(seq(1,10), seq(11,25), seq(26, 30))
y2 <- c(seq(1,10), seq(11,25), rep(25, 5))
line2 <- sp::SpatialLines(list(sp::Lines(sp::Line(cbind(x2,y2)), ID='b')))

lcp_network <- rbind(line1, line2)

cumulative_lcps <- create_lcp_density(lcps = lcp_network, raster = r, rescale = FALSE)
