accumulated events for aggregated locations

Discussion created by suhadfsl on May 6, 2014
please I need your help,  I have 190 towers distributed on a map , each one has events density , now I need to aggregate (cluster) each group of these towers in identified region with the sum of their (towers) events density i.e. the accumulated events density of the resulted region for the aggregated towers.

can you show me the way to do that ?
