Alidad (Noun)
Meaning 1
Surveying instrument consisting of the upper movable part of a theodolite including the telescope and its attachments.
Classification
Nouns denoting man-made objects.
Examples
- The surveyor carefully adjusted the alidad to ensure accurate measurements of the angles between landmarks.
- The alidad was a crucial component of the theodolite, allowing for precise calculations of distances and elevations.
- To take a reading, the surveyor rotated the alidad until the crosshairs in the telescope were aligned with the target.
- The alidad was mounted on a rotating axis, enabling the surveyor to measure angles in both the horizontal and vertical planes.
- After completing the survey, the team carefully disassembled the theodolite, storing the alidad and other components in a protective case.
Synonyms
Hypernyms
Meaning 2
Surveying instrument used with a plane table for drawing lines of sight on a distant object and for measuring angles.
Classification
Nouns denoting man-made objects.
Examples
- A surveyor carefully sets up the alidad to establish the plane of sight with a nearby reference point on the mountain range.
- In modern times the use of alidad with plane table surveying is no longer the dominant technique in measuring geographical terrains and contours.
- On-site team positioned their theodolite adjacent to a calibrated alidad installed to intersect collinear views during boundary markings in geography exploration project.
- Proper understanding and proper assembling skills on components for as alidad forms is often as indispensable asset, enhancing total geophysical effectiveness over others depending manual task use needs while mounting procedures generally will employ task tables techniques alongside mechanical gadgets availability through known on paper means based alidad that only demand fitting instructions usually
