a quick method
adopted for large surveys only
most accurate method
suitable for hilly terrains
Answer is Right!
Answer is Wrong!
The correct answer is: A. a quick method.
The direct method of contouring is a quick and easy way to create a contour map. It involves measuring the elevation of points on the ground and then connecting them with lines of equal elevation. This method is not as accurate as other methods, such as the trigonometric method, but it is a good option for small surveys or for creating a quick overview of a terrain.
The other options are incorrect for the following reasons:
- Option B: The direct method of contouring can be used for surveys of any size.
- Option C: The direct method of contouring is not the most accurate method of creating a contour map.
- Option D: The direct method of contouring is not necessarily suitable for hilly terrains. It can be used for any type of terrain, but it may be more difficult to use in hilly areas.
