Stereographic Projection Techniques for Geologists and Civil Engineers
Stereographic Projection Techniques for Geologists and Civil Engineers
$58.99
USDThe stereographic projection is an essential tool in the fields of structural geology and geotechnics, which allows three-dimensional orientation data to be represented and manipulated. This book has been designed to make the subject as accessible as possible. It gives a straightforward and simple introduction to the subject and, by means of examples, illustrations and exercises, encourages the student to visualise the problems in three dimensions. Students of all levels will be able to work through the book and come away with a clear understanding of how to apply these vital techniques. This revised edition contains additional material on geotechnical applications, improved illustrations and links to useful web resources and software programs. It will provide students of geology, rock mechanics, geotechnical and civil engineering with an indispensable guide to the analysis and interpretation of field orientation data.
- Contains many carefully drafted diagrams designed to aid the visualisation of three-dimensional problems
- Divided into short sections making it easy to locate and study a particular technique
- Contains links to useful Web resources and software

"Lisle and Leshon have written a fine and comprehensive introduction to a difficult topic. The visualization of three-dimensional structures and orientations of planes and lines within those structures is well described and the book is well worth its modest price." Richard E. Jackson, INTERA Inc.
"This is an excellent introduction to an important subject." Computers and Geosciences
