Question

If the ground is flat, the contour interval selected is:

• A. {Small}
• B. {Medium}
• C. {Large}
• D. {Extra large}

Hint:

For flat terrain, use a small contour interval to capture minor elevation changes accurately.

Answer 1

The Correct Option is A

Step 1: The contour interval is the vertical distance between successive contour lines on a topographic map. Step 2: In flat terrain, elevation changes are minimal, requiring small contour intervals to represent slight variations. Step 3: Larger contour intervals are used for steep terrains to avoid excessive contour lines. Thus, the correct answer is (A) Small.
