Dr. Ziad, you have very good patience in explaining how to derive the position of the station x as explained used for resection in theodolite surveying. I am looking for a reliable formula in the form of Microsoft excel formula such that position of x can be found by computing the data in excel cell format during site survey so as to compute the work required on the field there and then.

What angle should you aim for, for best accuracy when backsighting on 2 know points when carrying out a resection?
Thanks
Great

My doubt is the slope of line AB is rise /run = tan θ. i.e θ=tan -1(N/E). But, In ur case quadrant bearing calculations showing θ=tan -1(E/N). So , which one Is correct sir ?

Hi. We are not calculating the slope here. We are calculating the angle between the meridian and line AB.
Sir, Calculation on Stationing Method using Total Station is waiting.
How would you calculate WCB of BX on point B if E and N are both negatives, assuming north is straight up. I know angle B and WCB BA but then require WCB BX. Do you take angle B away from WCB BA to find Theta then take 360 away from theta to give WCB BX?

For context my angle B= 76’33/59.46// and my WCB of BA= 46’4//36.72

It depends on the position of X relative to line BA. You need to draw line BA and point X, then calculate WCB (BX) from the the drawing.

If point X is to the left of line BA, then WCB (BX) = 360 - (B - WCB(BA))

Wh 20:47 when inputting the calculation you have shown I end up with a different answer. How do you input this into your calculator when finding the missing angles. Thanks

How did get rid of the negative sign on the Quadrant bearing of AB

Because we used the absolute values of the change in easting and northing when calculating the QB.

Hello brother, can you tell me how to press the casket in the 5th point,Because my brother's answer is 15 seconds, and you see 35 seconds, generally speaking, my brother's answer is 78 ° 09'15 "My answer is 78 ° 09'35"

The Coordinate of the instrument point is (x,y,z), you calculated only (x,y), there are more steps to find (z). Thanks for your effort.
