We usually think of GPS (Global Positioning System) as a good thing, especially if we're using it to find our way from place to place. GPS satellites, radio signals, and receivers work together to pinpoint our location and get us to our destination. Hikers, bicyclists, and even golfers are finding ways to use GPS to improve their athletic experiences. The military installs GPS in many kinds of equipment, vehicles, and weaponry. GPS has surprising applications as well, such as tracking animals for conservation efforts. But many people are suspicious of this technology, especially when it's used to locate them without their consent. Many aspects of the GPS debate are explained, giving readers the ability decide for themselves where, when, and how satellite positioning should be used.

When taking a road trip today, some sort of GPS device is essential. It may be built into the car’s dashboard, or perhaps it’s just an app on a smartphone. But GPS is used for more than just finding your way! Readers will be fascinated by its beginnings as a military system and its many modern uses, such as catching criminals, predicting earthquakes, and creating maps. Colorful photographs illustrate real-life examples of GPS technology, military and civilian, and informative text clearly explains the science and math concepts behind the satellites and receivers used all over the world.

Somewhere in D.C., a vast computer complex churns through quintillions of data bytes about every American, living or dead. And one of them is you! Satellites circle in space, prying into your intimate family secrets, while underground groups plot how to clone your DNA. Your phone may be tapped, your office burglarized, your identity stolen. They're bugging your clothing and hacking your e-mail. There's no place to hide. Or is there? In this book, you'll learn about real, little-known secret programs run by both the public and private sectors. And once you're armed with that knowledge, you'll learn practical steps you can—and must—take to keep your private life private and lose Big Brother for good!

Since the publication of the bestselling second edition of The Global Positioning System and GIS, the use of GPS as an input for GIS has evolved from a supporting analysis tool to become an essential part of real-time management tools in wide-ranging fields. Continued technological advances and decreased costs have altered the GPS vendor landscape significantly and opened the door to an array of receiver and software options. Retaining the in-depth description that made the previous edition so popular, The Global Positioning System and ArcGIS, Third Edition has expanded its coverage to review the capabilities and features common to most receivers. While it emphasizes Trimble and Magellan hardware and Trimble TerraSync and ESRI ArcPad software to capture data, the text’s broadened coverage makes it useful with virtually any hardware/software packages, so readers will be able to collect GPS data and install it in ArcGIS—regardless of the data capture mechanism. Covering the latest developments in this emerging field, the third edition has been updated to include: New information on automated data collection Updates to the conversion of GPS data into GIS form with ArcGIS Desktop (v. 9.3) as well as ESRI software An examination of differential correction and improvements in accuracy of collected data Additional emphasis on ArcMap and Pathfinder Office Illustrations using ArcMap to combine GPS data with other data sets including raster DRGs, DOQs, DEMs, and various vector data sets Using a top-down approach, each chapter begins with a theoretical overview followed by self-study exercises and projects that provide step-by-step guidance on applying the concepts using GPS hardware or a PC. The text includes downloadable resources with GPS data sets for exercises in Trimble SSF and ESRI shapefile formats, plus other valuable learning resources.

The Global Positioning System and Geographical Information Systems, working in tandem, provide a powerful tool. Recent developments such as the removal of Selective Availability have not merely made these technologies more accurate but have also opened up a new seam of applications, particularly in location based services. The Global Positioning System and GIS is a clear text and guide to the use and integration of these powerful technologies, with each topic combining an overview with a step-by-step approach. This significantly revised and extended second edition now comes with a set of resources on a CD-ROM, including an instructor's guide, demonstration data and exercises. It is a straightforward introductory text for students and teachers on GIS/GPS courses as well as a practical and introductory field manual for mapping science professionals, giving basic practical guidance, particularly to the integrated use of ESRI's GIS software with Trimble's GPS hardware.
