4.8.24. Stereo-model

Try these first

1. 1.

   Define stereo-model.

   Hint

   Think about how you can see depth with two viewpoints.

2. 2.

   What is parallax?

   Hint

   Consider how this helps us measure heights.

3. 3.

   What is a stereo-model?

   • A two-dimensional image
   • A three-dimensional representation from overlapping photos
   • A method of drawing maps

   Hint

   Think about how depth is created in images.

4. 4.

   True or False: Parallax is used to determine the height of terrain features.

   • True
   • False

   Hint

   How does viewing an object from different angles help us measure its height?

5. 5.

   Given the parallax of an object is 30 mm in a stereo-pair with a scale of 1:400, calculate the height of that object.

   Hint

   Use the parallax to find height by multiplying by the scale.

6. 6.

   Critique the effectiveness of stereo-models in archaeological studies for landscape interpretation.

   Hint

   Think about the benefits of height perception in interpreting past human interactions with the land.
