For Trail Orienteering events, specific Foot Orienteering maps are used, where the detail and accuracy must have a very high precision in the area of the controls, because solving the problems requires a very detailed analysis of terrain and map.
The maps are drawn according to international specifications defined by the IOF, namely:
- ISOM – International Specification for Orienteering Maps.
- ISSprOM: International Specification for Sprint Orienteering Maps.
The scales used for Trail Orienteering maps are normally the scales used for Sprint races, which can be 1:3000, 1:4000 or 1:5000, depending on the nature of the terrain.
