Extract simple geometries

Description

Extract simple geometries

Usage

wk_flatten(handleable, ..., max_depth = 1)

wk_flatten_filter(handler, max_depth = 1L, add_details = FALSE)

Arguments

`handleable`	A geometry vector (e.g., `wkb()`, `wkt()`, `xy()`, `rct()`, or `sf::st_sfc()`) for which `wk_handle()` is defined.
`...`	Passed to the `wk_handle()` method.
`max_depth`	The maximum (outer) depth to remove.
`handler`	A wk_handler object.
`add_details`	Use `TRUE` to add a "wk_details" attribute, which contains columns `feature_id`, `part_id`, and `ring_id`.

Value

handleable transformed such that collections have been expanded and only simple geometries (point, linestring, polygon) remain.

Examples

wk_flatten(wkt("MULTIPOINT (1 1, 2 2, 3 3)"))
wk_flatten(
  wkt("GEOMETRYCOLLECTION (GEOMETRYCOLLECTION (GEOMETRYCOLLECTION (POINT (0 1))))"),
  max_depth = 2
)
