base plate | the rectangular plate of the orienteering compass on which the compass housing is mounted. |
cardinal points | the four principal points of the compass: north, east, south, and west. |

collecting feature | an obvious feature between you and the control that helps guide you. |
compass | instrument for determining directions with the help of a strip of magnetized steel swinging on a pivot. |
compass, conventional | a compass generally enclosed in a watchcase - type of housing. |
contour interval | the distance in height between one contour line and the one next to it. |
contouring | a method of traveling around an obstacle, such as a hill, by keeping at the same elevation, thus following a contour. |

topographic maps | maps with contour lines and of high precision; from the Greek topos , place, and graphein , to write |
variation | another term for declination. |
wayfaring | a leisurely form of orienteering in which enjoyment of nature takes precedence over the competitive aspects of the sport. Commonly called map hiking. |
aiming off | a method by which the orienteer aims to one side of a control instead of directly at it. |
