Excerpt from Coordinates of Elementary Surveying

I. For the purpose of study the subject of Elementary Survey ing may be divided into the following parts: (1) Coordinates of surveying, which are the magnitudes which serve to fix the position of a point, - ih space, on a surface, or on a line. (2) Surveying instruments, by means of which the magnitudes are measured. (3) Errors of measurement. (4) Methods of surveying, which deal with the practical application of systems of coordinates, either singly or in combination, through the use of various surveying instruments. (5) Computing and mapping, by which the measurements are combined and the results presented for convenient use.

Reseña del editor

Of PREFACE In my first eight years of teaching surveying in the customary way, stress was laid on those fundamental principles of the subject which are independent of the circumstances of surveying, namely personnel, equipment, nature of the survey and of the ground. Nevertheless it was to be observed that on subsequently taking up the study of railroad surveying too many of the students were deficient in grasp of fundamentals. Six years ago the experiment was tried of devoting a part of the lectures of the course in surveying to the fundamentals exclusively, and the following year the students were supplied with a mimeograph text covering this ground and were required to work many problems in connection therewith. The result of the experiment was gratifying. During the following three and a half years I had occasion to observe critically the work of several surveying parties employed on heavy railroad construction and was struck by the fact that nearly all of the cases of defective surveying were due to lack of grasp of the coordinates of surveying rather than to want of skill in the use of implements. The lack of familiarity with fundamentals was most often exhibited in failure to devise a scheme of check measurements which should be independent of the original measurements. It has been observed not infrequently that the young surveyor looks upon the different branches of surveying, e. g., land, city, mine and hydrographic surveying, as involving different fundamental principles of surveying, and this is because in his training the varying circumstances of surveying have been permitted to overshadow the unvarying principles. The foregoing facts supply the reason for making much of and formally presenting the subject of this book.
