8.8.1. Purpose

Try these first

1. 1.

   What is aerial triangulation used for?

   Hint

   Think about mapping techniques.

2. 2.

   Name one component necessary for aerial triangulation.

   Hint

   Consider what assists in accuracy.

3. 3.

   What does aerial triangulation aim to do?

   • Provide 3D models
   • Determine spatial coordinates
   • Enhance image quality

   Hint

   Think about its primary function.

4. 4.

   True or False: GCPs are only useful for small area mapping.

   • True
   • False

   Hint

   Consider their role in various contexts.

5. 5.

   Given a scenario where two overlapping images from different flights have been incorrectly aligned due to poor GCP placement, outline how you would adjust the images using block adjustment techniques.

   Hint

   Focus on the roles GCPs play in re-adjusting and correcting.

6. 6.

   Describe a case where aerial triangulation failed to provide accurate results. What were the main causes and how could they have been mitigated?

   Hint

   Consider the importance of proper planning and execution in data collection.
