Transform a spatial object to class sf

Source: R/gc_sf.R

Transform a spatial object to class sf

gc_sf(input, ...)

# S4 method for geom
gc_sf(input = NULL)

Arguments

input

the object to transform to class sf.
...

other arguments.

Value

If input is a geom and has attributes other than fid and gid, a "Simple feature collection", otherwise a "Geometry set". Several features of the geom are returned as MULTI* feature, when they have gid and optionally other attributes in common, otherwise they are returned as a single simple feature.
