Hydrographical Surveying
Excerpt from Hydrographical Surveying: A Description of the Means and Methods Employed in Constructing Marine ChartsI have endeavoured in the following pages to collect together information which has for the most part existed, but in a traditionary form, for many years.Circumstances have led to a partial break in this tradition, and it is no disparagement to the more modern treatises on nautical surveying to say that the young surveyor has no book to which he can refer for information on all details, as they, confessedly, do not enter into them.Belcher's, the former standard work, is out of print, and in many ways out of date, as though the main principles of chart-making must remain the same, the lapse of time and introduction of steam, &c., have placed many additional means at the disposal of the marine surveyor of to-day.Knowing that there are many older and more experienced hydrographical surveyors than myself, it has been with considerable diffidence that I have applied myself during a period of leisure to stop the gap, and I hope my brother surveyors will remember that I write not for them, but for those young officers who wish to become acquainted with the practical portion of our branch of the naval profession.The Appendix, largely composed of reprints of tables either falling out of print, or scattered about in different works, will, it is hoped, be found to save labour and time, and be useful to the Surveying Service at large.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
