The map Layer has around 1500 points. I am able to display all the points in the map without any problem but adding the cluster strategy to the layer does not work. The Cluster strategy functions when I limit the number of points to 100.

Is there a way to cluster large amount of points in Openlayers?

  • Can you explain what exactly was the solution in the end? I'm at a similar issue and your solution could be of help for more people. – mephistho Dec 18 '13 at 9:29

i think there is a problem with your code. in normal case Openlayers clustering doesnt make problem with 1500 points . to understand clustering strategy, you can check out openflights.org clustering tutorial here.

beside this did you examine openlayers clustering example.

  • Cluster Strategy Example, here
  • Extended clustering, here

if you share your code, we may check out it..

i hope it helps you...

    In addition, here's a pretty cool animated cluster strategy plugin. It extends OpenLayers.strategy.Cluster(). css.dzone.com/articles/animated-marker-cluster – geomajor56 Sep 13 '12 at 12:58
  • Thanks a lot for your answer..I figured out the problem and it was not the number of points in the cluster. – user9685 Sep 14 '12 at 9:39
