The practice of modern surveying is undergoing rapid change due to the availability of electronically controlled instruments, the widespread adoption of the Global Positioning System (GPS), and the proliferation of various geographic Land Information Systems (GIS/LIS). Nevertheless, the principles underlying these new technologies remain constant. In the tenth edition of this benchmark text, Frank Moffitt and John Bossler strike the appropriate balance between teaching students the fundamental principles of surveying and bringing them up to date on the technological advances that are changing the field. The tenth edition of this classic work completely modernizes much of the notation, form, and substance of the original. By removing much of the dated information, the authors have been able to add entire new chapters on GPS and GIS. Throughout the text, emphasis is placed on NAD 83 over NAD 27 as the new datum is being utilized more frequently.
