This book has been written primarily for freshman and sophomore students at the college level. The authors have concentrated on preparing a readable text that presents basic concepts and practical material. Each of the fundamental areas of modern surveying (geomatics) are discussed. Although the book is elementary, its depth and breadth make it suitable for self study, and for use as a reference by those engaged in the practice of surveying and its related disciplines such as civil engineering, forestry, geography, geology, landscape architecture, and others. This 10th edition has been completely revised and updated, and includes the newest developments in both field and office procedures in surveying. Many additions and changes have made this the most up-to-date textbook available in surveying. As with past editions, this text continues to emphasize the presence of errors in surveying, and practical suggestions resulting form the authors' many years of experience are interjected throughout the book.
