pathdistGen: Generate a stack of path distance raster objects

In ipdw: Spatial Interpolation by Inverse Path Distance Weighting

Generate a stack of path distance raster objects

Description

Generate a stack of path accumulated distance raster objects

Usage

pathdistGen(sf_ob, costras, range, yearmon = "default", progressbar = TRUE)

Arguments

sf_ob	sf object with point geometries
costras	RasterLayer cost raster
range	numeric. Range of interpolation neighborhood
yearmon	character. String specifying the name of the sf_ob
progressbar	logical show progressbar during processing?

Value

RasterStack object of path distances

Examples

library(sf)
sf_ob <- data.frame(rnorm(2))
xy   <- data.frame(x = c(4, 2), y = c(8, 4))
sf_ob <- st_as_sf(cbind(sf_ob, xy), coords = c("x", "y"))

m <- matrix(NA, 10, 10)
costras <- raster(m, xmn = 0, xmx = ncol(m), ymn = 0, ymx = nrow(m))
costras[] <- runif(ncell(costras), min = 1, max = 10)
# introduce spatial gradient
for (i in 1:nrow(costras)) {
  costras[i, ] <- costras[i, ] + i
  costras[, i] <- costras[, i] + i
}

rstack <- pathdistGen(sf_ob, costras, 100, progressbar = FALSE)
