Orienteering map

An orienteering map is a map specially prepared for use in orienteering events. It is a large-scale topographic map with extra markings to help the participant navigate through the course.

These maps are much more detailed than general-purpose topographic maps, and incorporate a standard symbology designed to be useful to anyone, regardless of native language. In addition to indicating the topography of the terrain with contour lines, orienteering maps also show forest density, water features, clearings, trails and roads, earthen banks and rock walls, ditches, wells and pits, fences and power lines, buildings, boulders, and other features of the terrain.

Orienteering maps meant for competition in forested areas are usually 1:15 000 or 1:10 000 scale and 1:4.000 for sprint maps in cities, and parks.

The International Orienteering Federation (IOF) publishes the standard for orienteering maps, including:

An orienteering map, and a compass, are the primary aids for the competitor to complete an orienteering course of control points as quickly as possible. A map that is reliable and accurate is essential so that a course can be provided which will test the navigational skills of the competitor. The map also needs to be relevant to the needs of the competitor showing the terrain in neither too much nor too little detail.

Because the competition must test the navigational skills of the competitor, areas are sought which have a terrain that is rich in usable features. In addition, the area should be attractive and interesting. Notable examples in the US include Pawtuckaway State Park, New Hampshire and Valles Caldera, New Mexico, both having many boulders and boulder fields, and a wide variety of other terrain types.

Orienteering maps are produced by local orienteering clubs and are a valuable resource for the club. Orienteering maps are expensive to produce and the principal costs are: the fieldwork, drawing (cartography), and printing. Each of these can use up valuable resources of a club, be it in manpower or financial costs. Established clubs with good resources e.g. maps and manpower are usually able to host more events.

In the early days of orienteering, competitors used whatever maps were available; these were typically topographic maps from the national mapping agency. While national mapping agencies update their topographic maps on a regular basis, they are usually not sufficiently up to date for orienteering purposes. Gradually, specially drawn maps have been provided to meet the specific requirements of orienteering.
