Q. Which the following is not a use of contour maps?

View solution

Q. From a given contour plan, the section along any given direction can be drawn to know the ______

View solution

Q. The indirect method serves as a basis for the interpolation of contours.

View solution

Q. The indirect method, guide points need not necessarily be on the contours.

View solution

Q. In indirect method, each contour is located by determining the positions of a series of points through which the contour passes.

View solution

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

View solution

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

View solution

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

View solution

Q. If the inclination of contour gradient is given, its direction from a point may be easily located either on the map or on the ground.

View solution

Q. If a level is used to locate the contour gradient, it is not necessary to set the level on the contour gradient.

View solution

Q. Which of the following cannot be used to locate the contour gradient in the field?

View solution

Q. _______ is a line lying throughout on the surface of the ground and preserving a constant inclination to the horizontal.

View solution

Q. In cross sections method, If there are irregularities in the surface between two cross lines, additional guide points may be located on intermediate cross lines.

View solution

Q. In the case of hilly terrain, the tacheometric method may be used with advantages.

View solution

Q. In cross sections method, cross sections are run traverse to the centre line of a road, railway or canal etc.
