Location-Based Data Analysis and Geolocation Artifacts
摘要
Advancement in mobile technology has provided various opportunities for the end user to use GPS devices. Nowadays, all smartphones, smart watches, cars, tablets, navigation devices, drones, palmtops, etc., have inbuilt GPS device and they store users’ movement and travel history on their local database and on cloud application. Cars also comes with inbuilt android systems for navigation. These smart devices could be configured with email ID like Gmail as iPhone required Apple ID(Email) and password after reset the device which could be same ID used first time during first configuration. Global positioning system (GPS) is a satellite-based navigation system which determines locations of GPS device anywhere on Earth. GPS device consists of arrangements of satellite orbiting the planet and their on-earth control tower(station) and GPS receivers. GPS devices receive signals from a group of satellites orbiting Earth, each transmitting its location and time. GPS devices determine location using a technique called trilateration, where they measure distances from multiple satellites to pinpoint an object's position on Earth.
