Map Reading
Duke of Edinburgh Hillary Award
Maps• 2D representation of the ground, showing
recognisable features and contour lines.
Types of Maps• Orienteering, topographical, park, track & aerial
maps.
Map Reading – Map Keys• Most maps use
symbols to represent certain types of features – eg a little fir tree symbol to indicate a forest.
• So that everyone can read the map, there must be a “key” which explains what each symbol means.
Margin Information
• Includes when the map was printed & by whom etc
Map Information
• Includes keys, scales, North line, Major lines, Minor lines, Point features etc
Map Features: ColoursBrown – landformsBlue – waterBlack – man-made Green – vegetationWhite – open land
Map Features: Contours• Contour lines join all land formations at the same
level• Closer together contour lines, the steeper the slope• Follow the contour line – you won’t be going up or
down-hill
Map Features: Thumbing• It may help you to mark the map periodically with
your current position • You can do this by making a mark with your thumb
Map Orientation• Orientate the map to the land when you read
it – everything on the map goes the same way as on the ground
• Map pointer – use a blade of grass on the map to show your current position or intended the direction

Grid References• Used to pinpoint exact locations within a grid
square. Eg square 4531 45 46 32

X is midway between 45 & 46 455 31 & 32 315
Grid reference is 455315
