So we’re gonna go ahead and add up all of our angles, 67 degrees, 17 minutes 47 seconds plus 217 degrees, 40 minutes, and 20 seconds plus 70 degrees, 4 minutes, 46 seconds, plus 48 degrees, 9 minutes, 53 seconds plus 136 degrees, 47 minutes and 39 seconds. Become best friends with it. So that you can use it on your exam.ģ.2.1 Adjusting latitudes and departures how to calculate a survey traverse ( Adding up all our angles )Īll right. This is approved by NCEES for all licensing exams. The best way to add up your angles is – by using this calculator. I just don’t you to be using a graphing calculator that you are not allowed to use on your NCEES licensing exam. So just disregard this angle right here when we’re adding up our angles. That’s why we measured this last one right here, which is actually from here to here. Because remember, that angle is this angle right here and that’s not necessarily, you know, going from one line to the other.

Not all these measurements are internal angles. Everything except for the first one is. Now the first step is going to be to add up all of our internal angles so that we can calculate what our misclosure is. We then take the average of these two so we can increase the level of accuracy with our distances – which is what we see right here.

And the backward distance is all the distances that we took when we were reading a backsight.

The forward distance is all of the distances that we took when we were taking foresight.

You’re also gonna notice that there’s a forward distance and a backward distance. Referring to the internal angles of our traverse.

Backsighted orange and foresighted green. We then backsighted the reference point and foresighted green. If you recall, we initially set up on pink. What goes into the data collection, all the different setups that we had, then come back to this blog and we will calculate all those coordinates using one reference point. Right here we have a sketch of our work and here are all the numbers that we measured in the field.

I hope you guys like it. In this blog we’ll be calculating the coordinates of our survey traverse, using the latitudes and departures between points taken from our angles and distances that we measured in the field.
