Engineering Surveying Sixth Edition by W. Schofield and M. Breach


The subject of engineering surveying continues to develop at a rapid pace and this has been reflected in the many and substantial changes that have been made in updating and revising the previous edition. The authors have taken the opportunity to examine in detail all the previous material making both minor and major changes throughout. As always, decisions have to be made as to what should be retained that is still current and relevant and to identify the material that needs to be cut to make way for new text to describe the emerging technologies The subject of survey control is now treated in much greater depth. 

The chapter on traditional methods still in current practice is followed by a whole new chapter on rigorous methods of control, that is, the application of the technique of least squares in the determination of coordinates and their quality. This topic was dropped from the fifth edition of this book but now reappears in a completely rewritten chapter which reflects modern software applications of a technique that underlies much of satellite positioning and inertial navigation as well as rigorous survey control.

Satellite positioning brings up to date the many advances that have been made in the development of GPS and its applications, as well as looking to the changes now taking place with GLONASS and the European GALILEO systems. The chapter on underground surveying includes an enlarged section on gyrotheodolites which reflects new techniques that have been developed and the application of automation in modern instrumentation. The final chapter on mass data methods brings together substantial sections on simple applications of photogrammetry with the revolutionary new technology of laser scanning by aerial and terrestrial means.

Inertial technology, once seen as an emerging standalone surveying technology, now reappears in a completely new guise as part of aircraft positioning and orientation systems used to aid the control of aerial photogrammetry and laser scanners. In spite of all this new material the authors have been able to keep the same level of worked examples and examination questions that have been so popular in previous editions.
