Question

The curve which deflects to the right of the direction of the progress of survey is called as:

• A. Right hand curve
• B. Left hand curve
• C. Eastward curve
• D. Westward curve

Hint:

Right-hand curves deflect rightward from survey progress direction.

Answer 1

The Correct Option is A

The question pertains to the terminology used in surveying and geomatics, specifically in relation to the directionality of curves. When the curve in survey geometry deflects to the right of the direction of progress, it is identified as a "Right hand curve".

In surveying, knowing the type of curve is essential for accurate construction and navigation. Curves are classified based on their deflection direction as observed from a point on the ground moving in the designated direction.

Here are the definitions of the relevant terms:

• Right hand curve: A curve that deflects to the right from the observer's viewpoint. This type of curve turns in a clockwise direction relative to the observer's movements.
• Left hand curve: A curve that deflects to the left from the observer's viewpoint.
• Eastward curve: A hypothetical term not commonly used in standard terminology, focusing more on cardinal directions.
• Westward curve: Similar to the Eastward curve, this is not a standard directional term for curve classification.

In conclusion, the correct classification for a curve that deflects to the right of the progress direction in surveying is the Right hand curve.
