Through the use of any GPS-Tracking App (here: “Easy Trails” for iOS) and the following code in Gh, I mapped my weekend, which is considered as a normal day of study. Three basic points:   – Home – IAAC – Bakery Analyzing, than, the different speeds during the tracking I underline particular event during the path, such as “StratingPoints”, “MusicOn”, “Metro-PathInCompany”, “TrafficLight”, that give us different visualization concerning the “Speed Range”.
