This book is a great help for future surveying engineers who are at their first step in their job. This book tries to explain as good as possible many cases met in their daily job and I hope it will be useful for them in solving the problems they met each day. The exercises from this book and the project were solved together with my students and I saw that they were very interested in solving this type of exercises. So, I tried to make a selection of the exercises made with my students, choosing the most important exercises. I hope this book will be useful for many types of engineers.
