    How to cluster coordinates (latitude and longitude) on a map?

    Wissam Kahi

      How can I use the tableau new  Tableau 10 "Clustering" function on coordinates (latitude, longitude) to cluster together locations that are close to each other?

       

      Context: I have a geo-spatial coordinates about ~2000 locations (stores) in North America. Some are isolated and others are fairly clustered together. I would like to cluster them in groups so that the ones that are fairly close to each other are clustered together (I expect to have ~200 clusters ranging from 1 store alone to ~20 stores within a ~30 miles radius). I tried the clustering function from the analytics tab and I tried to feed it my coordinates, but it did not accept them. I find it weird as the k-means clustering is inspired from euclidian distances originally. Any advice?
