Besides finding the shortest path for walking, you can also plot the shortest path for driving: # find shortest route based on the mode of travel. distance. While the accuracy is comparable with other libraries for geodesic distance calculation, such as GeographicLib/geopy, the geodesic distance computation implemented here is optimized for speed and more suitable for computing large arrays such as needed for Gaussian Process regression with scikit-learn. Geodesic Distance Formula: The geodesic distance is the shortest distance on the surface of an ellipsoidal model of the earth. Let’s examine the query in more detail: First, the PARTITION BY clause divided the employees by departments.
