1.16.2. Factors deciding the contour interval

Try these first

1. 1.

   What is a contour interval?

   Hint

   Think about how contours represent elevation.

2. 2.

   Why is it necessary to have larger intervals for smaller scale maps?

   Hint

   Consider what happens when contours are too close.

3. 3.

   What is the relationship between map scale and contour interval?

   • Larger scale maps require larger contour intervals
   • Smaller scale maps require larger contour intervals
   • There is no relationship

   Hint

   Think about the details that smaller vs. larger scale maps show.

4. 4.

   True or False: The purpose of a map does not influence its contour interval.

   • True
   • False

   Hint

   Consider the differences between construction and recreational maps.

5. 5.

   You are tasked with creating a topographic map of a steep mountain range and a flat plain. Outline your approach for selecting contour intervals for each terrain, considering all relevant factors.

   Hint

   Ask yourself how different terrains offer unique challenges in mapping.

6. 6.

   Analyze a scenario where you have limited funds and time but need precision due to the purpose of a map. Discuss how you might proceed with contour interval selection.

   Hint

   Think about the balance needed between speed and accuracy based on project requirements.
