The horizontal distance between two successive contour lines is called the:
Correct answer: A. Horizontal equivalent
- A. Horizontal equivalent
- B. Contour interval
- C. Vertical interval
- D. Contour gradient
Explanation
The horizontal equivalent is the horizontal distance between consecutive contour lines. The contour interval is their vertical difference in elevation, which is a different quantity.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
