เนื้อหาย่อ : This book is designed for use in an introductory course in surveying such as those in junior colleges, technical institutes, and on-the-job training programs, as well as for self-instruction. It is designed to prepare the reader to perform successfully the duties of any member of a surveying feld party, ineluding the positions of instrumentman and chief-of-party, both in the field and in the office. It serves as a firm foundation for future studies in surveying and provides a means of obtaining a position which is recognized as one of the best starting points in many types of industrial nd engineering organizations. The book is written especially clearly and simply, and nearly every principle is illustrated by a figure. The problems are given in pairs. The two problems in a pair are similar except in detail, and although no answers are supplied for the odd-numbered problems, answers are given at the end of the book for the even-numbered problems. Suggestions for feld exercises are outlined. Chapter 14, covering plane trigonometry and logarithms, can be used for primary instruction or for review. The book assumes a very elementary knowledge of algebra and the ability to use the A, B, C, and D scales of a slide rule. Since most surveying computations are now made on desk calculating machines, machines of this type should be available to students and instruction should be given in their use. It is also recommended that copies of "Eight-place Table of Trigonometric Functions for Every Sexagesimal Second of the Quadrant" by J. Peters, published by Edwards Brothers, Inc., Ann Arbor, Michigan, be available for computation. This table gives the values of the natural sines, cosines, tangents, and eotangents to eight places for each second of arc. The student would then be able to fit into office routine with very little difficulty. Many surveying offices today are equipped with electronie computers. The different types vary too widely for inclusion in this text. If it is desired to study celestial observations, an ephemeris for the year is required.
