About this layer

Contour lines join places at the same height. Closely spaced lines usually show steeper ground; wider gaps show gentler slopes. Use the height labels and nearby waterways to understand ridges, valleys and possible routes.

What it is for

Closely spaced lines indicate steeper ground. Use the labels and terrain together to understand ridges, slopes and valleys.

Limits

Contours simplify the terrain at their map scale. Small workings, obstacles and local hazards may not appear.
