Land Navigation Handbook: The Sierra Club Guide to Map, Compass and GPS

by W.S. Kals, Clyde Soles

This bestselling manual—now thoroughly revised and updated—is designed for anyone who wants to chart a course in the hiker, backpacker, snowshoer, skier, fisherman, or hunter. Step by step, it teaches the skills that enable you to answer the vital Where am I now? Which way do I head to reach my destination? How far is it? And how long will it take me to get there?
Included here are the basics of interpreting maps and orienting by compass, as well as more advanced techniques for measuring distances and estimating travel times; determining and adjusting for local declination around the globe; using an altimeter to add the dimension of height to one’s position; and navigation by means of sun and stars. In updating the late W. S. Kals’s text, Clyde Soles focuses on the latest developments in technology and equipment, such as digital mapping software and handheld GPS units, and provides an overview of marine navigation for sea kayakers. Visuals include a full-color foldout topographic map for reference and practice, plus dozens of helpful drawings and photographs.
