initializeAreaRaster: Initialize an area raster for a 2.5D MKDE.

In mkde: 2D and 3D Movement-Based Kernel Density Estimates (MKDEs)

Initialize an area raster for a 2.5D MKDE.

Description

Initialize the surface area for a 2.5D MKDE.

Usage

initializeAreaRaster(mkde.obj)	

Arguments

mkde.obj

An MKDE object created using initialize2DMKDE

Details

After creating the MKDE object and setting the lower bounds in the z-dimension using setMinimumZfromRaster, this function computes the surface area of each raster cell and sets the dimension of the MKDE object to 2.5.

Value

Returns a 2.5 MKDE object with an initialized area raster.

Examples

library(terra)
fpath <- system.file("extdata", "pandadem.RDS", package="mkde")
pandadem <- terra::readRDS(fpath)
cell.sz <- mean(res(pandadem))
ext <- ext(pandadem)
nx <- ncol(pandadem)
ny <- nrow(pandadem)
mkde.obj <- initializeMKDE2D(ext$xmin, cell.sz, nx, ext$ymin, cell.sz, ny)

mkde.obj <- setMinimumZfromRaster(mkde.obj, pandadem)
mkde.obj <- initializeAreaRaster(mkde.obj)
