context_page_description: An orienteering map is a map specially prepared for use in orienteering competitions. It is a topographic map with extra details to help the competitor navigate through the competition area.
  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 publishes the standard for orienteering maps, including:
  ISOM, used for FootO forest maps.
  ISSOM, used for FootO sprint and TrailO maps.
  ISSkiOM, used for SkiO maps.
  ISMTBOM, used for MTBO maps.
context_section_description: 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.
  Maps produced specifically for orienteering show a more detailed and up-to-date description of terrain features. For example, large rocks above the soil surface do not normally appear on topographic maps but can be important features on many orienteering maps.  New features such as fence lines can be important navigational aids and may also affect route choice. Orienteering maps include these new features.
  Cartographer Jan Martin Larsen was a pioneer in the development of the specialized orienteering map.
