Rasterize an sf MULTIPOLYGON object — rasterise

This function rasterizes an sf MULTIPOLYGON object to a SpatRaster object. The function also retains an attribute table from the sf object, by assigning categorical ID values to the raster values. The rasterized SpatRaster object will also contain a legend derived from the attribute table of the sf object.

Usage

rasterise_multipolygon(sf_object, raster_res = c(100, 100), field = "ID")

Arguments

sf_object: An sf MULTIPOLYGON object. It must contain an attribute table, with at least one categorical ID (numeric).
raster_res: A numeric vector specifying the resolution of the raster. Default is c(100,100).
field: A character string specifying the field name to be used for rasterization from the sf object. Default is "ID".

Value

A SpatRaster object that is a rasterized version of the input sf object, with a legend derived from the attribute table of the sf object.
