Web27 jan. 2016 · As you’ll see shortly, k-means clustering is an iterative process. The demo program has a variable maxCount, which is used to limit the number of times the main clustering loop will execute. Here that value is arbitrarily set to 30.

WebK-means should be right in this case. Since k-means tries to group based solely on euclidean distance between objects you will get back clusters of locations that are close to each other. To find the optimal number of clusters you can try making an 'elbow' plot of the within group sum of square distance.
