Geocaching has steadily grown into a fun and enduring outdoor adventure and with the popularity of GPS units and the development of applications for nearly all of the most popular smartphone platforms, it has become an adventure that's available to pretty much anyone. In The Complete Idiot's Guide® to Geocaching, Third Edition, the editors and staff of Geocaching.com open the world of geocaching up to a much broader audience and take the reader through all of the core essentials for caching including how to play, tips and tricks for finding and placing caches, variations on traditional caching, and much more. In addition, the reader can learn about exciting new changes to the game and the new GPS-enabled games that will take cachers to an entirely new level of fun and adventure.

The ultimate global game revealed! The Complete Idiot's Guide(r) to Geocaching, Second Edition is a comprehensive, yet entertaining and easy-to-understand book for getting started and having fun with geocaching-the high-tech version of hide-and-seek for global positioning system (GPS) users. In this edition, two new tools of the game-Waymarking and Wherigo-are included. ? The Geocaching website, which began operating in 2000 and is owned by Groundspeak, Inc., is the first and currently the largest website devoted to Geocaching ? Today, well over 800,000 geocaches are registered on various websites devoted to the pastime ? Geocaches are currently placed in over 100 countries around the world and on all seven continents, including Antarctica

Describing the exciting and adventurous world surrounding geocaching--a worldwide hunt in which treasures are located using global positioning system (GPS) devices--this book offers an understanding and application of the principles and best practices of the game. What's different is that the authors wrap this knowledge in a tapestry of human stories that range from hilarious to touching. Paul and Dana Gillin interviewed 40 of the world's 50 most prolific geocachers as well as experts in container design, "extreme" geocaching and other dimensions of the game. They tell how this global activity inspires passion that has helped people heal frayed marriages, establish new friendships--and even save lives.

Global Navigation Satellite Systems (GNSS) and their associated technologies have advanced by leaps and bounds in the nine years since the first edition of this book was published. The concept of survey has changed, especially in the disciplines of geomatics and geoinformatics. This revised and updated second edition provides a thorough understanding of the basic principles and techniques of GNSS, analyzes all four active systems, and explains clearly how each of these systems works. Because of its straightforward treatment of the subject, readers will gain an insight into the techniques, trends, and applications of GNSS and develop knowledge on selecting an appropriate GNSS instrument. Written for students and practitioners in geoinformatics, geomatics engineering, surveying, and remote sensing and GIS, this introductory and practical book includes questions and exercises in each chapter. Key Features: • Furnishes detailed information on GPS, GLONASS, Galileo, BeiDou, and other regional and augmented systems • Provides practical guidance for surveying, mapping, and navigation with GNSS • Sheds light on the latest developments and modern trends of GNSS • Includes a detailed glossary of related terms • Contains many illustrations that complement the text • Exercises for each chapter • MCQ, solution manual for mathematical problems, and PPT as online resources

Explore the latest advances in this exciting and poplar GPS adventure.

Ten years after it all began, geocaching is still going strong. Both the number of geocaches and the number of geocachers are in the millions, in more than 100 countries, and continue to grow. This fascinating, high-tech yet family-friendly outdoor activity—which combines aspects of treasure hunting, cutting-edge navigation, and exploration—may be the fastest growing new sport on the planet. But there is much more to geocaching than what most people know. This revised and updated edition of The Geocaching Handbook covers everything the aspiring geocacher needs to get started, and it provides plenty of information to help practicing geocachers take their skills to the next level. Learn how the game began—in a foreword by its founding father, Dave Ulmer—and discover how to: • Select a cache listing and begin your hunt for the treasure • Buy a GPS receiver and use it to navigate to the cache • Create and hide your own cache for others to find • Practice backcountry safety and geocaching etiquette • Play other geo-games, such as “Are U Nuts?” and “Geodashing” • Connect with other geocachers through clubs and geo-events

"This book does the impossible: it makes math fun and easy!" - Sander Rossel, COAS Software Systems Grokking Algorithms is a fully illustrated, friendly guide that teaches you how to apply common algorithms to the practical problems you face every day as a programmer. You'll start with sorting and searching and, as you build up your skills in thinking algorithmically, you'll tackle more complex concerns such as data compression and artificial intelligence. Each carefully presented example includes helpful diagrams and fully annotated code samples in Python. Learning about algorithms doesn't have to be boring! Get a sneak peek at the fun, illustrated, and friendly examples you'll find in Grokking Algorithms on Manning Publications' YouTube channel. Continue your journey into the world of algorithms with Algorithms in Motion, a practical, hands-on video course available exclusively at Manning.com (www.manning.com/livevideo/algorithms-?in-motion). Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology An algorithm is nothing more than a step-by-step procedure for solving a problem. The algorithms you'll use most often as a programmer have already been discovered, tested, and proven. If you want to understand them but refuse to slog through dense multipage proofs, this is the book for you. This fully illustrated and engaging guide makes it easy to learn how to use the most important algorithms effectively in your own programs. About the Book Grokking Algorithms is a friendly take on this core computer science topic. In it, you'll learn how to apply common algorithms to the practical programming problems you face every day. You'll start with tasks like sorting and searching. As you build up your skills, you'll tackle more complex problems like data compression and artificial intelligence. Each carefully presented example includes helpful diagrams and fully annotated code samples in Python. By the end of this book, you will have mastered widely applicable algorithms as well as how and when to use them.
