Description
Unnest nested geometries
Usage
1
geos_unnest(geom, keep_empty = FALSE, keep_multi = TRUE, max_depth = 1)
Arguments
geom
A GEOS geometry vector
keep_empty
If TRUE, a GEOMETRYCOLLECTION EMPTY is left as-is
rather than collapsing to length 0.
keep_multi
If TRUE, MULTI* geometries are not expanded to sub-features.
max_depth
The maximum recursive GEOMETRYCOLLECTION depth to unnest.
Value
A GEOS geometry vector with a length
greater than or equal to geom with an attribute "lengths"
that can be used to map elements of the result to the
original item.
Examples
1
geos_unnest("GEOMETRYCOLLECTION (POINT (1 2), POINT (3 4))")
