Kurzbeschreibung:
This book contains invited chapters written by recognized experts in their respective topics, making it an authoritative and defining reference for this burgeoning field. Location-based services (LBS) are a new concept integrating geographic location (i.e., spatial coordinates) with the general notion of "services," such as auto emergency services and navigation systems, and mobile web services. With the development of mobile communication, these applications represent a novel challenge both conceptually and technically. This book describes in an accessible fashion the various concepts that serve as a support to mobile location-based services. The major issues to consider, together with their current solutions, are described formally and illustrated through a simple application. Contributors include: Shashi Shekhar, University of Minnesota; Clay Collier, Iro Systems; Mark Strassman, Autodesk ; Sarah Spiekermann; Humboldt University, Berlin; H. - Arno Jacobsen, University of Toronto; Christian S. Jensen, Aalborg University; Fredrik Bajers, Aalborg University; Lance McKee, OGC Consortium; Jörg Roth, University of Hagen; Holger Karl, Technical University, Berlin
Beschreibung:
Location-based services (LBS) are a new concept integrating a user's geographic location with the general notion of services, such as dialing an emergency number from a cell phone or using a navigation system in a car. Incorporating both mobile communication and spatial data, these applications represent a novel challenge both conceptually and technically.
The purpose of this book is to describe, in an accessible fashion, the various concepts underlying mobile location-based services. These range from general application-related ideas to technical aspects. Each chapter starts with a high level of abstraction and drills down to the technical details. Contributors examine each application from all necessary perspectives, namely, requirements, services, data, and scalability. An illustrative example begins early in the book and runs throughout, serving as a reference.
· This book defines the LBS field and identifies its capabilities, challenges, and technologies.
· The contributors are recognized experts from academia and industry.
· Coverage includes navigation systems, middleware, interoperability, standards, and mobile communications.
· A sample application, the "find-friend" application, is used throughout the book to integrate the concepts discussed in each chapter.
