Try these first

1. 1.

   What is an orthogonal projection?

   Hint

   Think about how dimensions are maintained.

2. 2.

   How does orthogonal projection differ from perspective projection?

   Hint

   Consider depth perception.

3. 3.

   What is the main benefit of using orthogonal projection?

   • A. It creates a realistic view
   • B. It maintains accurate measurements
   • C. It enhances artistic representation

   Hint

   Think about how dimensions are represented.

4. 4.

   True or False: Perspective projection shows depth but distorts size.

   • True
   • False

   Hint

   Reflect on how distance affects appearance in drawings.

5. 5.

   A city planner needs to create a uniform grid system for a new development area. Discuss the advantages of using orthogonal projection over perspective in this context.

   Hint

   What does uniformity allow in planning?

6. 6.

   You are tasked with creating a design proposal using aerial photographs. Explain the steps to ensure that the photographs are converted into orthophotos using orthogonal projection.

   Hint

   Think about the relationship between photo correction and mapping accuracy.
