Question

Suggest the method to overcome any obstacles in chaining where vision & chaining both obstructed.

Answer 1

$\huge\underline{\underline{\mathfrak \red{Answer}}}$

❏Chaining and Vision Both Obstructed. It sometimes happens that a survey line passes through some object such as a pond, a building, a river, a hedge etc. which prevents the direct measurement of that part of the line which the object intersects.

❏The interfering object in such a case is called on obstacle.
