Contour Drawing

If you’ve ever looked at an Ordnance Survey Map, you’ll have seen the contours – lines joining places which are the same height above sea level. You can spot high places, low places and places where the slopes are steep. The contours are drawn at equal intervals – there might be one every 5m or 10m.

But contour maps are useful for many things other than height. In meteorology, isobars link places where the atmospheric pressure is the same, we use isotherms for temperature, isotachs for wind speed and isohyets for rainfall.

How do you go about creating a contour map from a set of observations? 

Here are a few practise resources:
