"The material in the text is accurate and current. It is refreshing to have access to a textbook that is current with technological advances. The topice covered were covered well and organized effectively." - MARLEE A. WALTON, IOWA STATE UNIVERSITY
"It is a good beginning/intermediate text on surveying. I like the GPS-related chapters. Good job." - DOUGLAS E. SMITH, MONTANA STATE UNIVERSITY
" Elementary Surveying is a great textbook for teaching, but it is also a great reference book for surveyors, engineers, and contractors." - CRAIG S. MOORE, VIRGINIA POLYTECHNIC INSTITUTE AND STATE UNIVERSITY

This Elementary Surveying: An Introduction to Geomatics, Tenth Edition has been updated to reflect the changing nature of modern surveying practicecurrently often referred to as "geomatics." Since this new term is now generally accepted in English-speaking countries worldwide, and is consistent with modern practice as currently evolving in the United States, it is an appropriate addition to the book's title. It is hoped this new edition will not only serve the needs of its traditional surveying and engineering users, but that it will also be suitable for the expanding audience of spatial data users in various other disciplines.
Written primarily for freshman and sophomore students at the college level, the authors have endeavored to present a readable text that presents basic concepts and practical material in each of the areas fundamental to modern surveying (geomatics) practice. Although the book is elementary, its depth and breadth also make it ideal for self study. This tenth edition includes more than 400 figures and illustrations to help clarify discussions, and numerous example problems are worked to illustrate computational procedures.
The order of chapters in the book has been reorganized to better accommodate schedules followed in most surveying laboratories, particularly those in northern climates. Thus, the material on leveling has been presented ahead of distance measurement by taping and electronic methods. Discussions of total station instruments and angle measurements follow these topics. Recognizing the increasing importance of the global positioning system (GPS), this subject has been ;.moved forward in the chapter sequence to follow total station instruments and o; angle measurements. Also the GPS coverage has been expanded into two chaptersChapter 13 introduces the principles of GPS operation, and Chapter 14 discusses field and office procedures in using the equipment. The subjects of leasts-quares adjustments and coordinate geometry have been upgraded and moved from the appendix into separate chapters in the main text. This is consistent with the increasing importance of these two topics, which have become so vital in connection with both GPS and geographic information systems (GIS).
In keeping with the goal of providing an up-to-date presentation of surveying equipment and procedures, total stations are stressed as the instruments for making angle and distance measurements. Transits and theodolites, which are now only rarely used in practice, are just briefly introduced in the main body of the text. Similarly, automatic levels are now the dominant instruments for elevation determination, and accordingly their use is stressed. Dumpy levels, which nowadays are seldom used, are only briefly mentioned in the main text. However, for those who still use these instruments, they are covered in more detail in Appendix A.
In addition to the major changes noted above, other additions, revisions, and modifications have been made throughout the book. These include the following: A new section on surveying safety has been added, and the use of metric units has been expanded in discussion, in example problems, and in after-chapter homework problems. The latest versions of surveying equipment are presented, and include such devices as digital levels, reflectorless EDM instruments, laser alignment equipment, digital cameras and scanners. Discussion of metric stationing has been expanded within the topics of profile leveling, horizontal and vertical curves, and construction surveying. The material on state plane coordinates has been updated, and the chapter on control surveying has been substantially revised and expanded to present some introductory concepts of geodesy, and also provide greater depth of coverage on datums and reference coordinate systems. The coverage of condominium surveys has been expanded in the chapter on boundary surveys. In the chapter on photogrammetry, modern procedures and equipment have been presented, including the latest developments in softcopy photogrammetry and digital orthophoto production. Discussions on interfacing an aerial camera and GPS equipment in the aircraft to supplement ground control, and new airborne laser mapping systems are also presented. The chapter on GIS has been revised and updated. Website addresses that enable students to obtain additional information on many different topics are given throughout the book. Also, the bibliographies that follow each chapter have been updated.
A compact disc containing many useful computer programs accompanies the book. The CD has its own documentation in the form of help- and sample-data files. The disk contains programs for traverse computations for polygon, link, and radial traverses; area calculations; astronomical azimuth reduction; two-dimensional coordinate transformations; horizontal and vertical curve computations; and least-squares adjustments. It also contains trial versions of field-to-finish software.
As with past editions, this text continues to emphasize the theory of errors in surveying work. At the ends of most chapters common errors and mistakes related to the topics covered are listed so that students will be reminded to exercise caution in all of their work. Practical suggestions resulting from the authors' many years of experience are interjected throughout the text. More than 1000 after-chapter problems are presented to give instructors a wide choice in making assignments. A solution's manual is available to instructors who adopt the book.
