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 that is 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 are 1:15 000 or 1:10 000 scale. The International Orienteering Federation (IOF) publishes the standard for orienteering maps, including: ISOM (International Specification for Orienteering Maps), used for FootO forest maps. ISSOM (International Specification for Sprint Orienteering Maps), used for FootO sprint and TrailO maps. ISSkiOM (International Specification for Ski Orienteering Maps), used for SkiO maps. ISMTBOM (International Specification for Mountain Bike Orienteering Maps), used for MTBO maps.
