Fast point-in-polygon intersection for large numbers of polygons.

Finds the shared area between two polygons.

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

Exactly test if a point is inside, outside or on the boundary of a polygon

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

Beautiful, smooth animations for theme switching in React applications. Features Circle, Blur Circle, QR Scan, Polygon, Polygon Gradient, and Custom GIF animations with TypeScript support.

Takes any number of features and returns a rectangular Polygon that encompasses all vertices.

Finds the difference between multiple polygons by clipping the subsequent polygon from the first.

Finds the “balance point” of irregular shapes, like a country outline.

Takes a triangular plane as a polygon and a point within that triangle, and returns the z-value at that point.

Merges a specified property from a FeatureCollection of points into a FeatureCollection of polygons.
