Elements of surveying and navigation : with a description of the instruments and the necessary tables
A textbook of surveying and navigation by American mathematician Charles Davies, published by A.S. Barnes & Co. in New York in 1847 for students and practicing surveyors. The plates are line diagrams: lettered quadrilateral plots with compass points, dashed construction lines, numbered angles and triangulated sightlines, useful as spare geometric marks, angle notation and survey-plan motifs.
