Remove holes from polygon geometries

Source: R/remove_geom_holes.R

Removes polygon holes from an sf, sfc, or sfg object. With a positive max_area, only holes smaller than the threshold are removed.

remove_geom_holes(x, max_area = 0)

Arguments

x

An sf, sfc, or sfg object of type POLYGON or MULTIPOLYGON.

max_area

Maximum area of holes to remove, in the units of x (or square metres for geographic coordinates). Default 0 removes all holes.

Value

An object of the same class as x, with selected holes removed.

Note

For a faster alternative when max_area is unnecessary, see sfheaders::sf_remove_holes(): https://github.com/dcooley/sfheaders.
