Excerpt from Geodesy: Including Astronomical Observations, Gravity Measurements, and Method of Least Squares
In this volume the author has attempted to produce a textbook on Geodesy adapted to a course of moderate length. The material has not been limited to what could be actually covered in the class, but much has been included for the purpose of giving the student a broader outlook and encouraging him to pursue the subject farther. Numerous references are given to the standard works.
Throughout the book the aim has been to make the underlying principles clear, and to emphasize the theory as well as the details of field work. The methods of observing and computing have been brought up to date so as to be consistent with the present practice of the Coast and Geodetic Survey.
The chapters on astronomy and least squares are included for the sake of completeness but do not pretend to be more than introductions to the standard works. The student cannot expect to master either of these subjects in a short course on geodesy, but must make a special study of each.
The author desires to acknowledge his indebtedness to those who have assisted in the preparation of this book, and especially to Professor J.W. Howard of the Massachusetts Institute of Technology for suggestions and criticism of the manuscript; to the Superintendent of the Coast and Geodetic Survey for valuable data and for the use of many photographs for illustrations; and to Messrs. C.L. Berger Sons for the use of photographs of the pendulum apparatus and several electrotype plates. Tables XII to XVII are from electrotype plates from Breed and Hosmer's Principles and Practice of Surveying, Vol. II.
