Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Railway Right-of-Way Surveying This little book outlines a modern system of right-of-way survey ing, leveling, and mapping. Though the system as a whole applies particularly to railroads, the adjustment diagram feature will be found useful in the special adjustment of streets, canals, highways, and old boundary lines. It is hoped the suggestions here given will save time in the organization and prosecution of the work and above all will lead to accurate and permanent results. The method of survey herein described must not be confused with the common one of using the outside head of rail as a base line for locating the various structural features. Vast sums of money have been spent for such surveys, leaving no permanent field reference to lines run and recording sets of maps without any measurements whatever. Many of them have been ordered under the directing influence of rushing some kind of survey through as quickly as possible for pur poses of reconstruction hence no criticism is here offered. But there is no excuse whatever for property surveys not referable to fixed base lines, whether they result in the scale maps above referred to or in the so-called very complete maps, showing instrument lines run, angles and measurements, direct from the field book. The former class of maps is of little practical value, while the latter contains a mass of data not directly available.
