Distribution of emissions by a georeferenced image

Calculate the spatial distribution by a raster

Usage

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

Source

Example data is from Defense Meteorological Satellite Program (DMSP).

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

Examples

grid  <- gridInfo(paste(system.file("extdata", package = "EmissV"),"/wrfinput_d01",sep=""))
#> Grid information from: /home/runner/work/_temp/Library/EmissV/extdata/wrfinput_d01 
x     <- raster::raster(paste(system.file("extdata", package = "EmissV"),"/dmsp.tiff",sep=""))
test  <- rasterSource(x, grid)
#> Grid output: 99 columns 93 rows
image(test, axe = FALSE, main = "Spatial distribution by Persistent Nocturnal Lights from DMSP")
