(BQ) Part 2 book "Geopositioning and mobility" has contents: Location-based Services: Platforms and applications, geofencing, pedestrian navigation for the benefit of mobility, the application of satellite positioning systems in travel analysis. | Chapter 5 Location-based Services: Platforms and Applications 5.1. Introduction The emergence and development of mobile technologies has allowed global navigation satellite system (GNSS), location information and location-based services (LBSs) to be widely distributed and accessible. It has been strongly observed that these systems allow the improvement of users’ activities. Factors contributing to this evolution include the development of the Internet and related technologies, the understanding and exploitation of the potential of business-related processes and the impressive growth of mobile networks. Geopositioning is a technique used to locate a person, vehicle or any other mobile object. Because of the high rate of use of wireless networks and mobile devices, geopositioning applications occupy an important place in our daily activities and in various fields (e.g. health, business and domestic affairs). They give rise to numerous requests for services that are categorized as LBSs. An LBS is a web service integrating geographical information into business applications. It Chapter written by Wafaa AIT-CHEIK-BIHI, Ahmed Mohamed BAKHOUYA, Jaafar GABER and Maxime WACK. NAIT-SIDI-MOH, 104 Geopositioning and Mobility provides information that can be accessed from mobile devices via the mobile network, based on the geographical position of the device. LBSs are mainly used to identify the location of an object or a person relative to a given geographical position. Naturally, these go well beyond a simple pinpoint on a geographical map. Indeed, their purpose is to send a wealth of useful information in real-time. These informations are sent to users via services that use their locations or addresses to process their requests and post the results on a map. We may cite, for example, the calculation of an optimized itinerary (e.g. the shorter and faster) between two locations by avoiding congested areas and a search for nearby restaurants. Many base principles and .
