2. 2.

   Why are overlaps important in creating a mosaic?

   Hint

   Consider how puzzle pieces fit together.

3. 3.

   What does a mosaic allow us to do in photogrammetry?

   • Combine data from multiple sources
   • Create standalone images
   • Increase resolution of a single image

   Hint

4. 4.

5. 5.

   Given three aerial images with overlaps of 70%, determine how many images are needed to cover a 1000 square kilometer area if each image covers 200 square kilometers effectively.

   Hint

   How does percentage overlap affect the total area coverage?

6. 6.

   Analyze the impact of a significant tilt during the image capture on the final mosaic produced. Discuss how it can alter the interpretation of landscape features.

   Hint

   What happens when you tilt a camera while taking a photo?
