When Location-Based Services Meet Databases

When location-based services meet databases

As location-based services (LBSs) grow to support a larger and larger user community and to provide more and more intelligent services, they must face a few fundamental challenges, including the ability to not only accept coordinates as location data but also manipulate high-level semantics of the physical environment. They must also handle a large amount of location updates and client requests...

Supporting Location-Based Services in Spatial Network Databases

Location-based services (LBSs) utilize consumer electronics, mobile communications, positioning technology, and traditional map information to provide mobile users with new kinds of online services. Examples include location-sensitive information services that identify points of interest that are in some sense nearest and of interest to their users and that offer travel directions to their user...

Location - Based Services

Over the past ten years location-based services (LBS) have been variously touted as the next generation of GIS; as the killer application that will bring the GIS industry to its next level of prosperity; and as a growing threat to human privacy. This chapter attempts to provide a basic introduction to LBS, and a discussion of some of the major issues surrounding them. It begins with basic defin...

Location-Based Services

Location-based services (LBS) evolved from mobile service. A mobile service is determined by the interaction of the user, the mobile device, and the mobile provider. Since the value for the users depends on the context (i.e. environmental factors surrounding them), mobile services can be assigned to different context-aware services which are characterized by integrating information about the us...
