De clustering points in flex map

abukhan — Wed, 08 Jun 2011 20:15:15 GMT

Hi:

I load about 93000 points with clustering in the map...

It takes less than a minute (fluorinefx, flex and .net)..

However i also need to decluster these points (to show the exact location of these points)..

simply setting graphicslayer.clusterer = null takes long time and some time (script out )..

NOw my questions are

1) it there way to de cluster only within a certain map extent
(what I mean is when user zooms in , i will decluster only points within the view extent ,, remaining points outside the view extent will still be clustered)

2) Is there any effiecient way to decluster? (may be for the entire area or within the extent)

3) any other idea?

Thanks.

Are you using your own clustering, or the built-in API cluster classes?
