This is a book explaining the mathematics used by land surveyors during the course of boundary surveys. It provides a hands-on approach to commonly used equations and concepts covering angles, bearings, trigonometry, coordinate geometry and traverse closure. Many examples are given to help the reader understand the concepts. The presentation in this book is intended to be as simplified as possible and the author has attempted to provide clearly worded explanations of each subject. Although a background in algebra, geometry, trigonometry and statistics would be helpful, none of these is strictly necessary in order for the reader to work through these materials. This book is intended to be a companion book to "Land Surveying Simplified", written by this author, which is available on Lulu as and eBook or soft cover.
