The author focuses on a particular approach developed by Chauvenet which utilizes spherical trigonometry and the principles of geometry and plane trigonometry to solve a series of equations that enable a surveyor to determine the direction of the line by the angle of altitude and azimuth, and the sum and difference of the plane angles. The insights in this book provide depth and breadth in understanding how to find the direction of a line using stars.
