Control Descriptions

Orienteering is a worldwide sport. It is the aim of the IOF control description symbols to provide a standard means for orienteers from all countries to be able to understand control descriptions without ambiguity or the need for language translation. This booklet shows how the symbols can be used to do this.

How IOF control descriptions work

The purpose of a control description is to give greater precision to the picture given by the map of the control feature, and to indicate the location of the control flag in relation to this feature, thereby helping the competitor to better visualize the control site.

However, a good control is found primarily by map reading. Descriptions and codes can assist in this task, but should be kept as short and simple as is necessary to locate the control.

Note: Control descriptions should not be used to correct map errors.
