Question

Which type of survey accounts for Earth's curvature, enabling more precise measurements over large regions?

• A. Plane table
• B. Cadastral
• C. Topographic
• D. Geodetic

Hint:

Difference between surveying methods: \[ \boxed{ \begin{aligned} \text{Plane Surveying} &\rightarrow \text{Small areas, Earth's curvature ignored} \text{Geodetic Surveying} &\rightarrow \text{Large areas, Earth's curvature considered} \end{aligned} } \]

Answer 1

The Correct Option is D

Concept: Geodetic surveying is used for large areas where the Earth's curvature cannot be neglected. It provides highly accurate measurements by considering the Earth as a curved surface.

Step 1: Differentiate between plane and geodetic surveying.
• Plane surveying assumes the Earth is flat and is suitable for small areas.
• Geodetic surveying considers the Earth's curvature and is suitable for large regions.

Step 2: Identify the appropriate survey. Since the question refers to surveys over large regions accounting for Earth's curvature, \[ \boxed{\text{Geodetic Surveying}} \] is the correct answer. Therefore, the correct option is \[ \boxed{(D)\;\text{Geodetic}.} \]
