Uses of Conventional Surveying
Chain Surveying:
- Used for taking linear measurements in the field.
- One-dimensional measurements.
Compass:
- Used for measuring directions of survey lines.
Theodolite:
- Used for measuring angles of survey lines – both horizontal and vertical angles.
- 2-Dimensional measurements.
Dumpy level:
- Used to (i) determine elevations of given points with respect to a given or assumed datum; (ii) establish points at a given elevation with respect to a given or assumed datum.
- One-Dimensional measurement.
Plane tabling:
- Graphical method of survey in which the field observations and plotting done simultaneously.
Characteristics of Conventional Surveying
- Suitable for small to moderate areas of extent.
- Intervisibility between survey stations required. Therefore, range of work gets limited.
- Can only be used during day time.
- Cannot be used in all weather conditions.
- Requires more man power to accomplish the task.
- Takes more time to cover larger areas, i.e., time consuming process and therefore, owing to time limitation, the no. of points to be surveyed gets limited.
- Pressure of finances.
