[mapserver-users] How to avoid point from overlaying one another

Hi all,

I have a point layer that is displaying points of interest (POI). Each 
POI has a classification that I use with a class expression to display a 
different icon image for the POI. I some cities there are so many POIs 
in a small spatial area that they all pile on top of one another and 
make a mess.

Is there anyway to do collision avoidance with the points?

I can change the layer TYPE to ANNOTATION which will thin them based on 
the ability to label them but it does not control whether they will be 
overlapped anyway, just assures that the symbol will only get drawn IF 
the label will fit.

Thoughts?
