Extract coordinates as a tibble
geo_coordinates(x, ...)
| x | A geometry-like object, or one that can be
coerced to a geometry-like object using |
|---|---|
| ... | Unused |
A tibble with one row per coordinate and columns
feature and xy. Vectors that include mutli geometries
will have a part column, and vectors that include polygons
will have a ring column.
