Location data infrastructures underpin the development of services giving rise to IoT, through which an increasing number of things will not be only connected; but also, geographically located, leading to what Andy Hudson-Smith calls the ‘Geography of Everything’. Being so, location data have implications for the future of our cities, where smart devices equipped with sensors will feed real-time information to the systems of emergency, security, transport and surveillance. Anyone carrying a smartphone is potentially part of the network of sensors, leading to an increase in the amount of location data being generated, used and analysed. This research analyses such systems of mobility which evolve with real-time connectivity and locational tracking, and discusses their potential societal benefits and threats.
