Book Description

Excerpt from Triangulation in West Virginia, Ohio, Kentucky, Indiana, Illinois, and Missouri This publication brings together in convenient form for the use of engineers information in regard to the triangulation by the United States Coast and Geodetic Survey in six of the central States, namely, West Virginia, Ohio, Kentucky, Indiana, Illinois, and Missouri. The principal portion of these results is that part of the Transcontinental Triangulation, extending from the Atlantic to the Pacific, Which lies within the limits of these six States. The field work was commenced in 1871 and finished in 1893, having been in progress during the whole interval, except during the years 1875, 1876, 1877, and 1888. A full account of the Transcontinental Triangulation has been published in so far as the features of special interest to the scientists are concerned.1 Only the positions for the primary stations were there published, and but a few descriptions of stations. The positions of all stations, primary, secondary, and tertiary, are published herein on the North American (formerly called the United States Standard) Datum, together with all available descriptions.
