Hello,

I am currently trying to calculate distance between conflicts and population clusters. I would like to show intensity by identifying if an event i.e. - 1 or more, 5 or more and 10 or more events has has occurred within a given radius (5, 10 or 15kms). First is the conflict data and next the data on clusters (only a sample of one is provided)
