If only I had discovered you earlier in the semester. Now I feel cheated out of my tuition. You're my instructor, for free, giving me the actual skills and I'm forced to give the university thousands of dollars because they are the mafia who control handing out the tickets (diplomas) needed for getting a job.
i thought it mattered alot on whether you add or subtract 180 and the angle(im proabably doing it wrong). but i did it kinda randomly to keep the number within 360 and got it not returning to its origonal azimuth. sorry, random CE undergrad
Mr Todd you said when dealing with counterclockwise we have to -180 but from the way you calculated bc you added back bearing of AB to interior angle of B ?
I thought that surveyors just used compass directions from 0* to 90*? So why are the inside angles measured from 0* to 360, and why is the best way to measure the angles?
Hi Todd, I have a question. When we are doing traverse corrections we also correct latitudes and departures. That will in turn change the bearing angles of the sides slightly. How do we balance the angles and coordinates at the same time?
You are correct. The traverse course bearings (or azimuths) after adjustment will differ by a few seconds from their original computed values. To determine the post-adjustment bearings, perform an inverse computation for each traverse leg using the adjusted points coordinates. The compass rule (Bowditch rule) adjustment in the video balances the measured angles first before adjusting latitudes and departures and thus the point coordinates. It is a two step process. To get true simultaneous adjustment, we can use the least squares adjustment process - not a manual process, but best done with a software application like Microsurvey Star*Net or Carlson SurvNet.
