1.17.2. Methods of plane tabling

Try these first

1. 1.

   What tool is used for levelling the plane table?

   Hint

   Think of how we ensure surfaces are flat.

2. 2.

   What is centring used for?

   Hint

   It's related to alignment.

3. 3.

   What is the first step in using a plane table?

   • Centring
   • Levelling
   • Orienting

   Hint

   Think about the importance of a flat surface.

4. 4.

   True or False: The intersection method requires three stations to locate an object.

   • True
   • False

   Hint

   Recall how triangulation works.

5. 5.

   You are tasked with using the intersection method to locate a distant tower. You position two survey stations and measure angles to the tower. How would you plot the tower's position on your map?

   Hint

   Think about triangulation – one point, two angles.

6. 6.

   Given a scenario where you need to survey a dense forest area, which method would you use and why? Explain your reasoning.

   Hint

   Consider what type of environment you're working in.
