Azimuth Angles. One way to describe directions in surveying is by using azimuth. The azimuth of a line is the horizontal directions measured clockwise from a zero direction which points north from the station occupied. Every ...
WebReverse: 272°14'50", 272°14'48", 272°14'52" 2. Direct and reverse directions observed with a total station instrument from point A to points B, C, and D are listed. Determine the values of the three angles, and horizontal misclosure. WebApr 4, 2024 · The average of the three angles in the second example should be 0. Ah! So if you have angles 359°, 0°, and 1° and draw them together, they are all 1 degree apart, just as 179°, 180°, and 181° are; but in the latter case averaging yields the angle you expect (the one in the middle), but in the former it doesn’t. I started to see the point:
WebRather than pointing to the center, you may take direct and reverse pointings on opposite edges (fig. 15-13). Pointings are made with the single portion of the vertical cross hair without regard to the location of the horizontal cross hair. ...
