Creates rectangular grid for emission allocation

make_grid creates a sf grid of polygons. The spatial reference is taken from the spatial object.

make_grid(spobj, width, height = width, polygon, crs = 4326, ...)

Arguments

spobj: A spatial object of class sp or sf.
width: Width of grid cell. It is recommended to use projected values.
height: Height of grid cell.
polygon: Deprecated! make_grid returns only sf grid of polygons.
crs: coordinate reference system in numeric format from http://spatialreference.org/ to transform/project spatial data using sf::st_transform. The default value is 4326
...: ignored

Value

A grid of polygons class 'sf'

Examples

if (FALSE) {
data(net)
grid <- make_grid(net, width = 0.5/102.47) #500 mts
plot(grid, axes = TRUE) #class sf
# make grid now returns warnings for crs with form +init...
#grid <- make_grid(net, width = 0.5/102.47) #500 mts
