Server-side Map Clustering


Marker Clustering is used to display large number of markers on the map. It is a visualization technique for the analyst to make sense out of the large data on a map.

Google Map offers marker clustering which is performed on the client-side. The spatial information needs to be sent to the client to perform the clustering, which is also how implement this. This could pose issues if data is sensitive or large to be transferred over via mobile broadband.
