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

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

Tesselates a polygon or multipolygon into a collection of triangle polygons using earcut.

turf multipolygon module

Convert Input to a GeoJSON-Like MultiPolygon Geometry

Return random position inside geoJson Polygon or MultiPolygon

Transform a GeoJSON Polygon or MultiPolygon to a list of geohashes that form it.

Determine if a point is inside a GeoJSON feature (polygon or Multipolygon).

Multipolygon data type to js array conversion.

Revert coordinates order for LineString, Polygon, MultiLineString and MultiPolygon features

enforce winding order for geojson

Converts polylines, wkts, wkbs, polygons, circles, rectangles, as well as standard geoJSON into geoJSON MultiPolygon Feature Objects. Converts wkb_list and FeatureCollection to arrays.

This project provides the basic functions for geometries. It allows to convert between `wkt`, `wkb`, `json` and our `well formatted geometry classes` to construct `Point`, `LineString`, `Polygon`, `MultiPoint`, `MultiLineString`, `MultiPolygon` and `Geome

Calculates the distance from a point to the edges of a polygon or multi-polygon.

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

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

pluggable polygon clipping with multipolygon and hole support: intersect, exclude, union, difference, divide

A tool to do boolean operation of Polygon and MultiPolygon.

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

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