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

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

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

Convert Input to a GeoJSON-Like MultiPolygon Geometry

Return random position inside geoJson Polygon or MultiPolygon

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

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

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

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

A tool to do boolean operation of Polygon and MultiPolygon.

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

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.

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

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.

An Suite to Combine <-> Decompose, Peel <-> Fill 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.
