Calculate the spatial distribution by a raster
rasterSource(r, grid, nlevels = "all", conservative = TRUE, verbose = TRUE)Source
Exemple data is a low resolution cutting from image of persistent lights of the Defense Meteorological Satellite Program (DMSP) https://pt.wikipedia.org/wiki/Defense_Meteorological_Satellite_Program
Data avaliable https://www.ospo.noaa.gov/Operations/DMSP/index.html
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: C:/Users/schuch/Documents/R/win-library/4.1/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")
