FeatureLayer Cluster More Than 500 Points?

[RyanCoodey]

So I realize the ArcGIS Server has a limit of 500 features it can return (1,000 in v10)... We have multiple field locations and one field might have 20,000 points.  I was hopeing clustering would still show this large count in one bubble when zoomed further out... but it only shows bubbles till they add up to 500.  Is there no way to use clustering to show them all?

Thanks a lot!

Hi Miri,

I understand you've changed the maximum features returned from 500 to 50000.

Is it really 50,000 (and not 5,000) ?

Yes, it was 50,000...

How do you access this service? Lan or Wan?

LAN.  Took about 10 seconds to grab all the features though.

Did you do cluster or regular queries? If you did clusters, wasn't it too heavy for the featureLayer to handle so many features?

We clustered, the application would actually crash if we didn't cluster (plus would be too chaotic).  The clusters rendered great though after waiting for the initial load.  Sounds like the new ArcGIS Runtime for WPF has improved rendering/display for lots of features so with it you may not need the cluster if its not wanted.

We actually are not using this anymore today...  The users did not like the initial load time (but did really like the functionality).  I'm hoping maybe one day there is server side clustering.  Hope that helps some...

*EDIT* Just realized what forum this was in... We did this with the WPF API not Silverlight, so using the new runtime might not be an option for you.

Hi Ryan,

Thank you for your answer.
I guess if it took you 10 secs. in WPF, it will take me ages with SilverLight.
I wish too, that Esri will develop server-side clusters for Handling more than 1000 features (or other number of maximum records returned).
It is very nice in demos and samples but it's not applicable in real world  implementations.

Thanks a lot,
Miri
