Define and differentiate between Plane, Geodetic, Topographical, and Cadastral surveys.

Step 1: Answer Question 1a.

• i) Plane survey: Assumes the Earth's surface is a flat plane, ignoring its curvature. It is suitable for small areas where the effects of curvature are negligible.
• ii) Geodetic survey: Accounts for the Earth's curvature and shape. It is used for large areas and high-precision work, often involving national control networks.
• iii) Topographical survey: Measures natural and artificial features of an area to determine their relative positions and elevations, creating maps that show relief and contours.
• iv) Cadastral survey: Establishes, re-establishes, and defines land boundaries, property lines, and ownership for legal purposes, often for land registration
