暫譯: 為無線網路創建位置服務

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.
