Watch hello dears!
here in this short tut we will be learning the horizontal distance determination by leveling machine, theodolite,tachometer
or any other instrument with which we can use graduated staff rod.
this video will provide basic formula by which we can get our approach so easily.
and the formula we will use for this approach is given below.
H.D = ( upper hair reading - lower hair reading) constant
h.D = horizontal distance
upper hair reading , lower hair reading and the constant detail is in lecture..
lets watch the lecture to know better how can we apply the above formula
for horizontal distance determination.
thank you dears for watching...............
