Flow type declarations for [GeoJSON](https://tools.ietf.org/html/rfc7946).

Splits GeoJSON Objects that cross the Antimeridian. See [RFC 7946 Section 3.1.9](https://tools.ietf.org/html/rfc7946#section-3.1.9)

Converts rfc7946 geojson polygons to d3 compatible ones: d3 requires clockwise winding whereas rfc7946 specifies the opposite. See https://github.com/d3/d3-geo/pull/79

Provides helper functions to create GeoJSON features, like points, lines, or areas on a map.

Combines a FeatureCollection of Point, LineString, or Polygon features into MultiPoint, MultiLineString, or MultiPolygon features.

Takes a GeoJSON feature and returns points at all self-intersections.

Returns the shortest path from start to end without colliding with any Feature in obstacles.

Checks if two geometries have an area of overlap without one being completely contained inside the other.

Polygonizes a set of lines that represents edges in a planar graph.

Converts a polygon to a line string.

Takes a Feature and a bbox and clips the feature to the bbox using lineclip.

Takes a kinked polygon and returns a feature collection of polygons that have no kinks.

Takes a line and returns a line at offset by the specified distance.

Lightweight utility for input validation and data extraction in Turf.js. Ensures GeoJSON inputs are in the correct format and extracts specific components like coordinates or geometries.

Returns the closest point, of a collection of points, to a line.

Takes polygons or multipolygons and an optional mask, and returns an exterior ring polygon with holes.

Takes any LineString or Polygon and returns the overlapping lines between both features.

Finds points that fall within polygon(s).

Finds the nearest point on a line to a given point

Creates line segments from a GeoJSON feature.
