A very fast JavaScript library for geospatial point clustering for browsers and Node. supercluster supports property aggregation with the following two options. Map, a function that returns cluster properties corresponding to a single point. Reduce, a reduce function that merges properties of two clusters into one.

Features

  • Load an array of GeoJSON Feature objects
  • For a given zoom and x/y coordinates, returns a geojson-vt-compatible JSON tile object with cluster/point features
  • Returns the children of a cluster (on the next zoom level) given its id (cluster_id value from feature properties)
  • Returns all the points of a cluster (given its cluster_id), with pagination support
  • Returns the zoom on which the cluster expands into several children
  • Generate ids for input features in vector tiles
