Cross-sections regularly appear in Part One – Short Questions, where students have to interpret information from a cross- section drawing already produced.

A cross-section is a side view of a section landscape on an OS map (Fig. 12.15). It also shows if there is intervisibility between two points on the map. The following method should be used to draw a cross-section.
1. Link the two grid references (the outer points of the cross-section) with a straight-edged strip of paper.
2. Mark the strip of paper where it touches the two outer points and note the height of the land at the starting point and finishing point.
3. Now mark the strip of paper where it touches each of the contours between the starting point and the finishing point. Note the height of the contour line at each mark made on the strip of paper.
4. Mark the edge of the paper where it touches any feature of the landscape, e.g. a river, a road.

Intervisibility: Whether one place can be seen from another, there may be high ground such as a mountain in between.
