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

Converts a polygon to a line string.

Finds points that fall within polygon(s).

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

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

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

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

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.

Mutex locks for async functions

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

Checks if a point is inside an area, like a city boundary.

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

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

output coverage reports using Node.js' built in coverage

Takes a grid of values (GeoJSON format) and a set of threshold ranges. It outputs polygons that group areas within those ranges, effectively creating filled contour isobands.

Smooths a Polygon or MultiPolygon, based on Chaikin's algorithm.

Awaitable semaphore/mutex

Finds the nearest point on a line to a given point

Creates line segments from a GeoJSON feature.
