Control Card
The competitor uses a multiple-choice control card and interprets the map to choose which one of the control markers in the terrain represents the one marked at the map. In Elite Trail Orienteering, also none of the markers could be correct, leading to the answer "Zero". A less common form involves determining the position on a map of a control viewed from a set point 30 – 40 metres away.

Famous quotes containing the words control and/or card:
“Our culture still holds mothers almost exclusively responsible when things go wrong with the kids. Sensing this ultimate accountability, women are understandably reluctant to give up control or veto power. If the finger of blame was eventually going to point in your direction, wouldn’t you be?”
—Ron Taffel (20th century)
“Mothers are not the nameless, faceless stereotypes who appear once a year on a greeting card with their virtues set to prose, but women who have been dealt a hand for life and play each card one at a time the best way they know how. No mother is all good or all bad, all laughing or all serious, all loving or all angry. Ambivalence rushes through their veins.”
—Erma Bombeck (20th century)
