Polygonizes (Multi)LineString(s) into Polygons.
Implementation of GEOSPolygonize function (geos::operation::polygonize::Polygonizer).
Polygonizes a set of lines that represents edges in a planar graph. Edges must be correctly noded, i.e., they must only meet at their endpoints.
The implementation correctly handles:
Parameters
geoJson (FeatureCollection | Geometry | Feature<(LineString | MultiLineString)>) Lines in order to polygonize
Throws Error if geoJson is invalid.
Returns FeatureCollection<Polygon> Polygons created
This module is part of the Turfjs project, an open source module collection dedicated to geographic algorithms. It is maintained in the Turfjs/turf repository, where you can create PRs and issues.
