The first guide to developing user location applications
You are walking down a street and suddenly, your cell phone display flashes the news that you are 70 feet from a Starbuck′s and that you are entitled to a dollar off your next purchase. You have just witnessed an example of user location services, one of the exciting new generations of cell phone and handheld services. This book describes the architecture and operation of this technology. It also familiarizes readers with the new location services development standard, shows how to programming with GIS, provides GUI design guidelines, and uses real–world examples to teach valuable lessons on how to successfully develop and deploy user location applications for the wireless Web.
CD–ROM contains a host of tools for developing positioning and location services.

Creating Location Services for the Wireless Web
Professional Developer′s Guide
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.
