[mapserver-users] Stop CLUSTERING beyond scale

Thu Oct 12 05:55:12 PDT 2017

Hi,

I would say that the answer to your question is "No" but you do not need to be sad because you can do it in a different way bay making a scale dependent layer group. 

LAYER
GROUP "MY_FEATURES"     
NAME "WITH_CLUSTERS"
MINSCALEDENOM 20000
...
END

LAYER
GROUP "MY_FEATURES"     
NAME "WITHOUT_CLUSTERS_FOR_FORCING_THE_LABELS"
MAXSCALEDENOM 20000
...
LABEL
FORCE TRUE
...
END #LABEL
...
END #LAYER

Aihe: [mapserver-users] Stop CLUSTERING beyond scale

Hi list,

I would like to know if it is possible beyond a scale denom to  stop clustering. I have this issue because I cluster some overlapping point and it is impossible to symbolize the individually when they are clusterized...

I'm looking for this kind of feature:

CLUSTER
     MAXDISTANCE 20  # in pixels
     REGION "ellipse"  # can be rectangle or ellipse
     MINSCALEDENOM 2000  # At 1:2000, Mapserver stops clustering?
END

At this time, as an alternative, I use scaletoken managing various query to postgis. But this query is in mapunits, not in pixels...

Thanks!
