4.14.1.2. Semi-analytical aerial triangulation

Try these first

1. 1.

   Define Aerial Triangulation.

   Hint

   Think about how photographers capture the ground from above.

2. 2.

   What are Ground Control Points?

   Hint

   Consider their role in mapping.

3. 3.

   What is the primary purpose of aerial triangulation?

   • To capture images from the air
   • To determine spatial relationships of ground points
   • To measure surface temperature

   Hint

   Consider what is technically done with the photos.

4. 4.

   True or False: Minor Control Points are used only at the start of aerial triangulation.

   • True
   • False

   Hint

   Think about their placement in the process.

5. 5.

   Design a hypothetical aerial triangulation project for a coastal region with elevation changes. Identify GCPs and explain how you would ensure accuracy in your photographs.

   Hint

   Start with locations that are easily measurable.

6. 6.

   Evaluate the impact of incorrect LCP positioning on the final map. What steps would you recommend to mitigate these issues?

   Hint

   Consider the implications of visual representation.
