Distribution of emissions by a georeferenced image

Description

Calculate the spatial distribution by a raster

Usage

rasterSource(r, grid, nlevels = "all", conservative = TRUE, verbose = TRUE)

Arguments

r	input raster object
grid	grid object with the grid information
nlevels	number of vertical levels off the emission array
conservative	TRUE (default) to conserve total mass, FALSE to conserve flux
verbose	display additional information

Value

Returns a matrix
