Explain Selection of Suitable Method of surveying.

 It depends upon the types of area to be served. It also considers the effect of magnetic field due to electric current. For example, chain survey is used for the small area having fairly level ground and compass survey is used where there is no effect of electric field. Plane table survey is used for the area having open ground. Tacheometric survey is used for broken ground.

Plane surveying is suitable for a survey of small areas (up to 196 Sq. Km) where the earth's curvature does not affect the results and is conducted in small areas.

Chain survey is suitable in the following cases:

1. The area to be surveyed is comparatively small
2. The ground is fairly level
3. The area is open and
4. Details to be filled up are simple and less

Compass surveying is recommended when the area is large, undulating and crowded with many details. It is not recommended for areas where the local attraction is suspected due to the presenc....Show More

Compass surveying is recommended when the area is large, undulating and crowded with many details. It is not recommended for areas where the local attraction is suspected due to the presence of a magnetic substance.

Tacheometry surveying  is best suited when obstacles such as steep and broken ground, deep ravines, stretches of water or swamps are me.

The plane tabling is generally adapted for surveys in which high precision is not required. It is mainly employed for small-scale or medium size mapping.
