Cluster Spiderfier for Openlayers 3

Initial Developers:

• Kai Jauslin
• Peter Philipp

Inspired by https://github.com/alrocar/OLSpiderfy

How it works

The interaction will listen to events on sources which are instances of ol.source.Cluster and show each feature of the e.g. clicked cluster around the clustered feature.

Usage

Simply add the plugin as interaction:

var map = new ol.Map({
  layers: [raster, clusters],
  renderer: 'canvas',
  interactions: ol.interaction.defaults().extend([new ol.interaction.ClusterSpiderfier()]),
  target: 'map',
  view: new ol.View({
    center: [0, 0],
    zoom: 2
  })
});

Options

• displayGeometry: The geometry type to use for drawing the opening display: circle or spiral. Default: circle
• radius: The radius to use when drawing the opening geometry. Default: 50

Properties

When accessing a spiderfied feature you can access the layer the spider originates from using the property originLayer. Example:

feature.get('originLayer')
