4.26.2. Common scale in triangulation

Try these first

1. 1.

   What does GCP stand for in photogrammetry?

   Hint

   Remember, they are crucial for accurate mapping.

2. 2.

   What is the purpose of MCPs?

   Hint

   Think of them as support points in mapping.

3. 3.

   What do GCPs serve in photogrammetry?

   • Control scaling
   • Reference points for accuracy
   • Identifying terrain features
   • None of the above

   Hint

   Think of the purpose behind using GCPs.

4. 4.

   True or False: MCPs are more critical than GCPs in triangulation.

   • True
   • False

   Hint

   Which points are considered foundational?

5. 5.

   In a scenario with three overlapping photographs where the GCPs differ in elevation by more than 5 meters, how would you approach scaling these images to ensure uniformity?

   Hint

   Think about the importance of true elevation representation in your adjustments.

6. 6.

   Given a set of aerial photographs with varying scales, determine how you could effectively use block triangulation to ensure a precise final map.

   Hint

   Consider how systematic connections will enhance the overall accuracy.
