Try these first

1. 1.

   What is a mosaic in photogrammetry?

   Hint

   Think about how photographs cover a larger area.

2. 2.

   Why are overlaps important in creating mosaics?

   Hint

   What happens to images when they are stitched without overlaps?

3. 3.

   What is the primary purpose of creating mosaics in photogrammetry?

   • To improve image quality
   • To cover larger areas
   • To capture scale accurately

   Hint

   Consider why multiple images are needed in mapping.

4. 4.

   True or False: Uncontrolled mosaics use ground control points to ensure mapping accuracy.

   • True
   • False

   Hint

   Think about the definition of controlled versus uncontrolled.

5. 5.

   You are tasked with creating a controlled mosaic. Explain the process and the importance of ground control points in ensuring accuracy.

   Hint

   Consider the role of each step in the overall accuracy of the mosaic.

6. 6.

   Discuss the limitations of uncontrolled mosaics. In what contexts might their use be inappropriate?

   Hint

   Think of situations needing reliable measurements or legal compliance.
