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
turf multipolygon module
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).
Revert coordinates order for LineString, Polygon, MultiLineString and MultiPolygon features
enforce winding order for geojson
a CLI utility to convert a multipolygon to a single polygon
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
Checks if two geometries have an area of overlap without one being completely contained inside the other.
Checks if a point is inside an area, like a city boundary.
Calculates the distance from a point to the edges of a polygon or multi-polygon.
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.
Converts polylines, wkts, wkbs, polygons, circles, rectangles, as well as standard geoJSON into geoJSON MultiPolygon Feature Objects. Converts wkb_list and FeatureCollection to arrays.
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.
`irregular-voronoi` makes it dead simple to create voronoi like diagrams constrained to irregular polygons. It ensures that no returned polygon is a MultiPolygon. That each point is in only Polygon. And that all polygons contain a point.
