4.14.1.1. Analog aerial triangulation

Try these first

1. 1.

   What is the primary purpose of analog aerial triangulation?

   Hint

   Think about the connection between photography and mapping.

2. 2.

   Name one type of control point used in analog aerial triangulation.

   Hint

   Consider the reference points marked on the ground.

3. 3.

   What is the main benefit of using ground control points in aerial triangulation?

   • They help create visual effects.
   • They ensure accuracy in mapping.
   • They make photo processing faster.

   Hint

   Think about the role of accuracy in surveys.

4. 4.

   True or False: Minor Control Points are selected at varying distances from the principal point.

   • True
   • False

   Hint

   Recap the specific conditions for MCP selection.

5. 5.

   Given three GCPs at different elevations, describe how you would ensure uniformity in aerial photographs. What processes would you employ?

   Hint

   Consider how these processes relate to elevation differences.

6. 6.

   Design a theoretical experiment where you take aerial photos, and analyze one section where elevation varied drastically. How would you correct the resultant errors in your mapping?

   Hint

   Think about the recalibration process required in such scenarios.
