[mapserver-users] howto draw amount of points features of one layer depending on scale

[David Percy]

If you treated them as labels when zoomed out (maxscale 50000 for 
example), then you could take advantage of the label colission features 
of mapserver to avoid overlaps.

when zoomed in further you could have another layer (minscale 50000 for 
example) that shows all the detail...

so you would have two layer definitions in this case...
Cheers,
Percy
