ENG 2130 Lecture Notes - Propagation Of Uncertainty, Azimuth
Document Summary
To process a closed traverse with the compass rule, not as the least-squares adjustment does. This laboratory can be a good starting point for the novice to practice azimuth and coordinate calculations, error propagation, understanding closure errors and how to distribute them and calculate them, and calculate the final coordinates for the traverse points. = tan-1 (ej - ei) / (nj - ni) = [0. 5 cm + 5/1,000,000 225. 850 m 100 cm/m] = 0. 612925 cm.
