Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> 50r - What does it represent in a topographical map?

• A. Relative height of the feature
• B. Benchmark height of the feature
• C. Triangulation height of the feature
• D. Spot height of the feature

Answer 1

The correct option is A Relative height of the feature

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Relative height is the height of a feature with reference to the height of the surrounding land and not to the mean sea level. It is represented by the height with a small ‘r’. Benchmark height is the height of a place actually marked on a stone pillar, rock or shown on a building as a permanent reference. It is written as BM 62.3 m.
