How many methods of contouring are present? Explanation: There are 2 methods of contouring: direct and indirect. In direct method, the points of elevation are located physically and then plotted on the map. Indirect method uses contouring with the help of grids.

How do you create a contour survey?
- Contour lines run close together near the top of the hill, indicating very steep ground.
- A uniform slope is indicated when contour lines are uniformly placed.
- A plane surface is straight and equally placed.
- A ridgeline is shown when higher values are inside the bend in the contour.

How many types of a compass are used in surveying?
There are two main kinds of magnetic compass used in surveying, both of which are included in the collection – the Surveyor’s compass and the Prismatic compass. The surveyor’s compass is usually the larger and more accurate instrument, and is generally used on a stand or tripod.
Which of the following scale is used to plot control map?
The horizontal scale is used to plot a contour map.
Contours are the most accurate method of representing relief features.
How do you survey contour lines?
In this method, the contours to be located are directly traced out in the ground by locating and making a number of points on each contour. These points are then surveyed and plotted on plan and the contours drawn through them.

What is chain survey?
Chain surveying is the branch of surveying in which only linear measurements are made in the field. This is suitable for the survey of small areas with simple details and an area that is fairly flat. It derives its name from the fact that the principle equipment commonly used is the chain.

How do you calibrate a frame?
- Stand the A Frame and mark the positions of both legs on uneven ground.
- Wait for the string and weight to pendulum and finally rest.
- Mark the position onto which the string is on the rail = A.
- Exchange the leg positions.
- Allow the string and weight to rest after swinging.
- Mark position on rail B.

How do you use an agricultural frame?
Place one leg of the A-Frame on the benchmark and shift the other leg until the plumbline settles at the centre of the A or the midpoint of the crossbar. Drive the second stake at the new site where the leg of the A- Frame rests. Move the A-Frame so that one leg touches the last stake.
How do you make a contour plan?
To produce a contour plan a surveyor takes a series of levels over the site at regular grid spacing. These readings are recorded in a surveyor’s log book and converted to RLs (reduced levels), which are plotted onto a grid overlaid on the site plan. A draftsperson can then draw lines of best fit between equal RLs.
