Creates rectangular grid for emission allocation

Source: R/make_grid.R

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

make_grid(spobj, width, height = width, crs = 3857)

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.

crs

coordinate reference system in numeric format from http://spatialreference.org/ to transform/project spatial data using sf::st_transform. The default value is 3857, Pseudo Mercator

Value

A grid of polygons class 'sf'

Examples

if (FALSE) { # \dontrun{
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

} # }
