- To determine the elevation of a point such as B in Fig. 24 in the text, the following procedure was used: With the transit set up over a point such as A whose elevation is 128.3 ft, the height of the transverse axis above A was 4.84 ft and the vertical angle b between the horizontal line CD through the transverse axis and the line of sight to the point B was +12º 42'. Then a point such as E was marked on the ground on the line between A and B and at a horizontal distance from A equal to 50.00 ft. Finally, with the transit set up over the point E, the difference in elevation between the point A and the transverse axis F of the transit at E was found to be 3.47 ft, and the vertical angle d between the horizontal line through F and the line of sight to the point B was +18º 07'.
