What is horizontal distance called?
The horizontal distance traveled by a projectile is called its range . A projectile launched on level ground with an initial speed v0 at an angle θ above the horizontal…
Why do surveyors measure horizontal distances?
Surveying and highway construction practice use horizontal distances rather than slope distances. This is necessary because the horizontal distance between two points does not change even if the ground is disturbed.
What are various methods of horizontal distance measurement?
Choosing the most suitable method
| Section1 | Method | Remarks |
|---|---|---|
| 22* | Pacing with a passometer or podometer | For quick, rough estimates |
| 21* | Ruler | Especially useful for sloping ground |
| 23** | Chaining using a rope | Cheap |
| 24** | Chaining using a band or tape | Best results with steel lines |
Which instrument is used for measuring horizontal distance?
Standard Equipment
The standard instrument used for measuring horizontal distances is the Steel Tape. A Constant Tension Handle is usually applied as well. Since both ends of the tape need to be firmly and accurately held, taping is usually a two man operation.
