Question

discuss advantages of indirect method of contouring.​

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

Indirect method- In this method, spot level is taken at the regular interval along predetermine line on the ground the work is then plotted on plan and then the required contour line is drawn by the process of interpolation. The indirect method is less tedious and speedy as compared to the direct method.
