Book Description
Excerpt from Automatic Surveying Instruments and Their Practical Uses on Land and Water Nevertheless there are a great number of military, civil and scientific purposes for which the accuracy obtainable by the Pedograph and the Cyclograph is sufficient. For some such purposes, moreover, it must surely be of great value that the automatic record of the traversed road or line can be obtained in the dark Of night, in fog, or during a march through high grass, bush or woodland (impeding the View) with no more labour or difficulty than at other times or elsewhere, at least with regard to the line of traverse itself. I have no doubt that for military sketches or recon naissances the Pedograph and the Cyclograph will in future be found a means of greatly adding both to the speed and facility of such work, as well as to the choice of personnel employed in it. It was a good plan to supplement the pacing instrument, the Pedo graph, by a wheeling instrument, the Cyclograph, which is less affected by inclinations of the line of traverse. Wherever a vehicle with this instrument attached to it may be employed, or wherever a bicycle can be trundled by its dismounted rider, the Cyclo graph will give the distances and therefore the plan fairly correctly, while in the use of the Pedograph by a pedestrian with little experience in pacing over Sloping ground, a light Slope or little declivities on. The traversed line will soon prove to be a source of loss to the accuracy Of the record drawn. Besides, the speed of a survey by the aid of the former instrument is of course still greater than by using the latter.
