[OpenLayers-Users] Cluster Layers - Correct placemark format?

[Allan Henderson]

Hi there,

I'm trying to implement a Cluster layer from a KML feed.  The feed on  
it's own is working fine but all falls apart when I try a cluster  
strategy.  So I'm thinking this method doesn't work - will clustering  
work on a geojson feed instead?  If not - what's the best format to  
ensure it all works?  I'm running a GeoDjango system so can switch  
format fairly easily.

Thanks,

Allan
