The ninth edition of Paul Wolf and Russell Brinker's best-selling text, Elementary Surveying, has been substantially revised so that students are informed of the latest technological developments in both field and office work. A highly readable introduction to the field of surveying (and past winner of the National Award for Excellence), this textbook emphasizes the theory of errors and correlation of theory and practical field methods. To remind students that surveyors must constantly strive to reduce the sizes of errors and eliminate mistakes, lists of typical errors and mistakes are given at the end of most chapters.
