Create raster of equally spaced cells. The distance between centre of cells
in both x and y dimension is equal to cell_size.
create_raster(geometry, cell_size, side_offset = 0)sf data.frame containing geometry which should be cover by
the raster.
numeric specifying the distance for equally spaced cells.
numeric specifying the side offset, distance added to the convex hull
of input geometry to generate raster for KDE. Good estimate is usually the same value as band width of KDE.
