Excerpt from Photography: Applied to Surveying

It would seem from the scarcity of published information on the subject of this treatise, that its practical value has not been justly appreciated. In foreign countries, and particularly in France, photography has been for a considerable period applied to surveying; and the results show a saving of time and labor that cannot be attained by any other known means; and, as in ordinary surveying, an accuracy that is directly proportioned to the quality of the instruments employed and to the care exercised in the fieldwork. In the United States, photographs are sometimes used as addenda to an important map, because they are recognized as conveying information to be otherwise gained only by actual inspection of the tract or subject represented; and when it is considered that in themselves they present all the data necessary for the construction of a map, thus rendering field-work other than that required for their production unnecessary, then certainly this method needs but to be better known to be appreciated.

In his own practice its value is so strongly impressed, that the author feels it a duty to try and present the subject in a plain and concise manner, trusting that others may so improve and enlarge upon it, that this method of surveying will not fail to become more generally understood and practised.

Of the numerous foreign authors whose recent works have been referred to for information may be mentioned Laussedat, Girard, Gossin, Hannot, Bornecque, Javary, Tissandier, Dufaux, Pizzighelli, Keucker and Colson. Acknowledgment is also due for information obtained from the periodicals La Revue d'Artillerie La Nature and the Bulletin de la Société Franqaise de Photographie.
