What is a contour interval, and what is it on the 1 : 50,000 toposheets of the Survey of India?
Original Khojo Papers practice question — not from a past board paper.
Answer
The contour interval is the difference in height between two consecutive contour lines. On the 1 : 50,000 series it is usually 20 metres.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The interval is kept constant on a sheet so that the spacing of the lines directly indicates the steepness of the slope.
