8.8. Aerial Triangulation

Try these first

1. 1.

   Define aerial triangulation.

   Hint

   Think about the relation between images and points.

2. 2.

   What are tie points?

   Hint

   Consider what connects two photographs.

3. 3.

   What is the primary purpose of aerial triangulation?

   • To enhance image quality
   • To determine point coordinates
   • To increase photo overlap

   Hint

   Think about what aerial triangulation achieves.

4. 4.

   True or False: Ground Control Points (GCPs) are irrelevant in aerial triangulation.

   • True
   • False

   Hint

   Recall the importance of GCPs in mapping.

5. 5.

   You are gathering aerial footage of an extensive suburban area. Describe what steps you would take regarding aerial triangulation to ensure effective mapping.

   Hint

   Consider what information would be essential to have before taking the photos.

6. 6.

   Aerial photographs taken have large areas of water and cloud cover. Discuss how this may impact your aerial triangulation efforts.

   Hint

   Think about how each area contributes to or detracts from the triangulation process.
