Résumé

Location services are emerging as one of the most important and anticipated tools of the new wireless Web. For instance, these services enable you to instantly get a map of where you are using your handheld device. Or, by pressing one key, you can retrieve the yellow pages for your location. But there is an entire system behind the convenience that delivers a user's location to the Web server.

In this book, noted author Johan Hjelm covers the all-important standards that will enable location application development, and describes the architecture and operation of those services. Concentrating on the convergence between GPS (Global Positioning Systems) and positioning in the mobile network, the book also talks about the GIS (Geographical Information Services) standards and how to build a Web site that uses them.

Introducing wireless developers to these new standards and tools, this reader-friendly book delivers:

A content and software developer's guide
Case studies from research projects
User interface design guidelines
A look at how location standards can help locate people who dial 911
Appendices that discuss XML, WAP 2.0, and CC/PP
Examples from existing systems

The CD-ROM contains trial versions for several useful tools for developing location-dependent applications services, as well as specifications for the GIS standards from the Open GIS Consortium.

Professional Developer's Guides
The Professional Developer's Guide series provides the first in-depth look at recent or emerging programming technologies. Experienced programmers and developers will find comprehensive coverage of new programming standards as well as code, sample programs, developer's tools, and applications that will make programming for a new technology much easier.
