GPS WAYPOINTS: WASHINGTON is a very handy reference tool designed for anyone who uses the Global Positioning System for personal navigation. Inside you will find over 15,000 waypoints compiled from USGS 7.5-minute topographic maps. Just some of the feature categories included in this book are lakes, reservoirs, dams, springs, passes, saddles, summits, camps, campgrounds, parks, beaches, cities, towns, airports, landing strips & mines. With this book, you no longer have to go through the cumbersome & sometimes confusing process of extracting coordinates from a topo map. Just go to the category for the type of feature you want, look up the name, & the coordinates can be in your receiver in less than a minute. With thousands of coordinates right at your fingertips, you will find many fun & time saving ways to use this book. You can plan your next outing or find the elevation of a nearby summit, airstrip, or town. You can also use the latitude & longitude listed in this book to find the location of a feature on your map. Indeed, this book will provide great value even if you don't own (or use) a GPS receiver.
