mkde (version 0.2)

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

Description

Initialize the surface area for a 2.5D MKDE.

Usage

initializeAreaRaster(mkde.obj)

Value

Returns a 2.5 MKDE object with an initialized area raster.

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.

Examples

library(raster)
data(pandadem)
cell.sz <- mean(res(pandadem))
ext <- extent(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)
