1.16.1. Contour interval

Try these first

1. 1.

   What is a contour interval?

   Hint

   Think about how it helps us read maps.

2. 2.

   How does terrain influence contour intervals?

   Hint

   Consider the visibility of changes in elevation.

3. 3.

   What does a smaller contour interval indicate?

   • More detail in hilly areas
   • Less detail in flat areas
   • No relevance to mapping

   Hint

   Remember how elevation changes are represented.

4. 4.

   True or False: Larger contour intervals are always better for flat terrain.

   • True
   • False

   Hint

   Think about how flat land appears on a map.

5. 5.

   You have a flat area needing a contour map for a future park. Suggest the contour interval and explain your rationale considering the park's use.

   Hint

   Think about how people will move and use the park.

6. 6.

   Design a scenario for a hilly landscape where the contour interval of 10 meters would be inappropriate. Discuss the consequences of this choice.

   Hint

   Reflect on if steep slopes are accurately indicated with larger intervals.
