Get to know the new mapping standards ahead of O-Ringen

This summer’s O-Ringen in Sweden’s High Coast region may be the first exposure to the new mapping standards for many orienteers. If this will be your first encounter with the new standards, make sure to learn the new symbols.

- People need to wake up before O-Ringen, says map controller Hans-Åke Öström.

New mapping standards were adopted back in 2017, but it takes time for such a change to take effect for all new maps and competitors. As a result, many orienteers will see the new symbols for the first time during O-Ringen 2018.

- These changes will lead to a clearer and more easily readable map, which is one of the goals for the new standards, says Hans-Åke Öström, who is the map controller for O-Ringen 2018 together with Sven Lundbäck.

All of the new maps created for O-Ringer follow the new mapping standards. This includes all of the training maps, which means that you can become familiar with the new standards by arriving a day or two earlier and training on these maps.

Open rocky hilltops mapped with grey

Rocky hilltops that lack any kind of vegetation will now be marked with grey, but such spots will not be especially common during O-Ringen. On the other hand, various shades of yellow will be frequent on top of Örnsköldsvik’s open mountains, which are often covered with moss or some other type of low vegetation.

- Two of the stages will feature large open areas with bare rock and scattered trees here and there. This will be shown with the “scattered trees” symbol, yellow with white dots, which is meant to indicate areas that have occasional trees, but are mostly very open, says Öström.

More changes

The new map standards introduce several other changes:

  • Springs will no longer be indicated by blue rings. Instead, the symbol will be a blue square.
  • Form lines will now be drawn using thinner lines than previously.
  • The space between dots indicating stony ground will correspond to the degree of rockiness: the closer together the dots, the stonier the area. This is stated more explicitly in the new mapping standards.
  • The route from the clock start and the start triangle will now be added to control descriptions and shown by a dashed line on the map. This part of the course had previously not been included in the calculation of course length.
  • North lines on the map will now have to be parallel to the map’s edge.


Hans-Åke Öström is issuing a challenge to all O-Ringen participants:
- It’s important to be aware of the changes ahead of O-Ringen in order to avoid unnecessary mistakes. Pre-runners made several mistakes when testing the
