Tacheometry Application Multiple Choice Question
(A) Where chaining is impossible
(B) For populous area
(C) In broken ground
(D) For extremely accurate survey
Explanation
Tacheometry is a rapid surveying method that uses a theodolite and a stadia rod to measure horizontal and vertical distances indirectly. It is particularly effective in broken ground, where uneven terrain or obstacles make direct measurement by chaining difficult or impractical. Tacheometry is also used in preliminary surveys where speed is prioritized over high precision.
Key Notes
- Tacheometry is ideal for broken ground or undulating terrain, where chaining is challenging due to slopes, obstacles, or uneven surfaces.
- It is not suitable for populous areas, as buildings and crowds can obstruct the line of sight for the theodolite.
- Tacheometry is not designed for extremely accurate surveys, as methods like total station or precise leveling offer greater precision.
- This technique is widely used in civil engineering for reconnaissance and preliminary surveys in challenging terrains.
Note: Tacheometry is an efficient surveying method for broken ground, enabling rapid measurements in areas where traditional chaining is impractical, supporting effective planning in civil engineering projects.
