get_grid(res = 0.5, crs = leaflet:::epsg4326, val = NA)

Arguments

res

resolution, in decimal degrees (default 0.5)

crs

coordinate resolutions system, ie projection (default geographic coordinate system 4326, ie WGS84)

Value

global raster with extent -180 to 180 longitude, -90 to 90 latitude and specified resolution
