Paperback. Etat : New. Print on Demand. This book offers precise leveling results of a line from Brigham, Utah, to San Francisco, California, established in 1912 by the United States Coast and Geodetic Survey. The author describes the methods and instruments used, noting the lengths of rods, index corrections, and mean lengths. The text discusses the Brigham, Utah to Beowawe, Nevada; Beowawe to Marmol, Nevada; and San Francisco, California to Marmol, Nevada sections, as well as the agreement of elevations at Brigham and circuit closures. The discussion of errors includes probable accidental and systematic errors, and the study of systematic errors considers the following conditions: clear or cloudy sky, forward and backward running of a line, and time of day. The author concludes by noting that every new line added to the precise level net will have some influence on the elevation of nearly every bench mark in the net.
