You can cluster spatial latitude-longitude data with scikit-learn's DBSCAN without precomputing a distance matrix. But simple Euclidean distance doesn’t cut it since we have to deal with a sphere,. Haversine Formula has its own law that is all equations are used based on the shape of a spherical earth by eliminating the factor that the earth is slightly elliptical (ellipsoidal factor). It is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior). It is incredibly intuitive to use, simple to implement and shows great results in many use-cases. For example, Euclidean distance between the vectors could be computed as follows: dm. Get lat/long given current point, distance and bearing.
