Understanding Location-Based Systems: 1
In recent years, technology has presented us with innovations we probably never thought were possible. Time and again, several systems that revolutionize operations in age-old industries are pioneered. One of the sectors that have witnessed massive advancements is the geospatial industry. More so, since several companies are becoming increasingly interested in location information and the potentials of geographical technology, we will continue to welcome more ideas in the geospatial industry.
It is normal to wonder if any relationship exists between Geographical information systems as a spatial technology and Location-based systems. For context, Location-based systems are the platforms that ensure location data and spatial information derived through GIS are extended to end-users via the internet or wireless networks.
Notably, since location information can now be modeled to better understand customer targeting, smart cities and tracking, security detailing, it has become the bedrock for any valid development. The integration of technology to obtain real-time location information formed the basis of location-based services.
What are Location-based systems (LBS)
Location-based systems describe any technology that combines geospatial technologies and real-time location tracking to provide information about an individual’s instantaneous location. In simple terms, LBS are geographically oriented information systems that communicate with users directly through telecommunication networks. The technology consistently provides targeted information in real-time based on the geographic location of the object of interest. Typically, location-based systems transmit information through wireless communication networks that include mobile devices, vehicle navigations systems, and PCs.
How does LBS work?
A true LBS application aims to provide personalized services to mobile users whose locations are in change. Location-based services (LBS) provide personalized services to the subscribers based on their current position using global navigation satellite system (GNSS), geographic information system, and wireless communication technologies. Regarding data, LBS receives data from various sources such as remote sensing, positioning systems like miniaturized sensors, topographic maps, and transportation data sources. The data from the various sources often need to be handled in LBS simultaneously and dynamically to give users specific information.
The basic questions that LBS users are concerned about include: where am I currently? What and where are the nearest locations of interest? How do I get to a location of interest? The questions may arise in different contexts, however, Location-based technology attempts to solve them with a comprehensive data system. Notably, a large base of individuals and group now involve LBS in their industry and day-to-day life to better achieve their goals. The increasing demand for commercial LBS has driven geo-information experts to focus on more accurate positioning solutions. The positioning solutions involve accurate, real-time positioning to connect users to points of interest and advises them of the current conditions such as traffic and weather conditions, or provides routing and tracking information using wireless devices.
It is important to integrate the mobile computing technology and GIS technology to meet the needs of LBS, which is considered one of the most promising applications of GIS. There are several features inside a typical internet-enabled device that can provide location information. The most common are GPS, RFID, Wi-Fi, and cellular, they are the LBS propagators.
