Cassandra Heatmaps ================== Cassandra can generate client-side heatmaps in GeoServer by defining a style and using the built in ``gs:Heatmap`` process within GeoServer. To start, add a new SLD style to GeoServer named "heatmap" and use this sld :download:`clientside-heatmap.sld ` Now you can change the style parameter to be styles=heatmap in the Layer Preview or PNG preview in GeoServer.
