8.15.2. Factors Affecting Accuracy

Try these first

1. 1.

   What is camera resolution?

   Hint

   Think about how many pixels make up the image.

2. 2.

   Why are GCPs important?

   Hint

   Consider their role in relation to real-world locations.

3. 3.

   What is the primary benefit of camera resolution in photogrammetry?

   • Captures more detail
   • Reduces image size
   • Speeds up processing time

   Hint

   Consider how clearer images contribute to precision.

4. 4.

   True or False: Environmental conditions have no effect on image quality.

   • True
   • False

   Hint

   Think about how light and weather impact photos.

5. 5.

   You are tasked with a photogrammetry project in an area that frequently experiences misty conditions. What strategies can you employ to ensure high accuracy?

   Hint

   Consider both timing and techniques in your solution.

6. 6.

   You find that the accuracy of your photogrammetric model is compromised due to insufficient GCPs. Propose a plan to address this issue.

   Hint

   Think about how adding more points can help improve the overall model.
