Mrs Smith’s Geography class have produced some fantastic models of landscapes using contours.
Height on maps
Maps show height in a number of different ways:
This map extract shows exact heights by a black dot with a number next to it. The number is the height above sea level in metres. The blue triangle represents atriangulation pillar.
Contour lines are usually drawn at 10 metre intervals on a 1:50,000 scale map and at 5 metre intervals on a 1:25,000 scale map.
Maps are sometimes shaded to show the height of land.
