Q1:

From any point on the surface with a given inclination

A only one contour gradient is possible

B two contour gradients are possible

C indefinite contour gradients are possible

D all the above.

ANS:C - indefinite contour gradients are possible

To locate the contour gradient, the level is set at a commanding position and reading on the staff at the first point is taken.

From a single instrument station, several points at a given gradient can be located 7.

In a direct method, the contour to be plotted is actually traced on the ground.
