[OpenLayers-Users] Cluster Strategy and Google Layer

[Eric Lemoine]

Hi. The EPSG:900913 projection should be set in the map options. In
this way your vector layer is also a 900913-projected layer. If your
vector points are expressed in 4326 you have to have them re-projected
before the're added to the layer. Eric
