The Instructor’s Manual has been prepared as a convenience for instructors who adopt, for use in
their classes, the textbook ELEMENTARY SURVEYING (AN INTRODUCTION TO GEOMATICS), 13th
Edition, by Charles D. Ghilani and Paul R. Wolf. As a benefit to the instructor, each problem
consists of the book question and a derived solution. For most questions a reference to the
equations, section, and/or paragraph containing the answer has been included together with a
copy of the relevant material from the text. This is provided so that useful feedback and
references to the appropriate parts of the book can be easily provided to the students. Every
attempt has been made to provide correct responses to the questions, but most assuredly, a few
mistakes may have occurred. Please accept our apologies for them and correct them in your
printouts. Since there will be no reprints of the Instructors Manual, corrections will not be made
to these files. However, any erratum that is found is the book will be graciously accepted by the
author to update subsequent printings of this and future editions.
