I found a discussion on My Life Blog which offers a formula for finding the coordinates of a PD Theodolite,which I though might be helpful to a surveyor using this type of instrument.

 


Calculation of measurement with measurement theodolite.melakukan with Theodolite would be more time consuming calculations Dlm coordinates and elevation data let alone done manually using a calculator without the help of software ms excel at this pc.berikut calculation formulas with manual measurement involves counting theodolite.Perhitungan flat distance (D) skewed distance (S) and height difference (△ H). and after that we calculated would begin to calculate the coordinates X, Y, Z.
The formula: 
D = ((ba-bb) -100) * (sin V) ^ 2

S = ((ba-bb) -100) * sin V
△ H = tan (90-V) * D + IH-TH
Coordinate

Kor.X = SIN AZ * D + X ST

Kor.Y = COS AZ * D + Y ST 

EL .= △ H + EL ST where the vertical angle V = AZ = Azimuth ST = Station tool tool TH IH = high high = target / beacon meters


 

Has anyone ever used this formula or this instrument?  Have anything to add or change in this formula?

interesting....perhaps you might like to start a new discussion in this group and show us some of the formulas you were taught in the Philippines...you may know some that others on the network have not been exposed to..
