MTBO survey and cartography

Both Emily and Hans Jørgen work in the summer months surveying and drawing MTBO maps. With their wealth of international MTBO experience, they are perfectly placed to draw maps to a high standard. MTBO maps are typically converted foot-O maps (although they can be drawn from scratch), using special symbols for the track network to show rideability/speed and width. The maps are different to foot-O maps as they only use one colour green (to show impassable forest) and remove most point features (depressions, gullies etc). Rock features and buildings are enlarged and converted to 70% black.

Map scale is typically 1:10000 or 1:15000. 1:7500 is sometimes used for sprint events in urban terrain.

Hans Jørgen worked at O-Ringen 2012 to draw the maps for the sprint, middle and long distances as well as planning all the courses. They both worked for O-Ringen 2013 to draw the maps for the sprint, middle and chasing start as well as course planning and drawing new map sections. They were both heavily involved in the daily organisation of the MTBO event.

Additional MTBO maps have been drawn by Emily and Hans Jørgen in: Mora/Borlange (Sweden), Hønefoss/Gardermoen (Norway) and Sheffield/Yorkshire/Wiltshire/Berkshire/Dorset (England).

Foot-Orienteering survey and cartography

Emily works part-time in the summer drawing maps for foot-orienteering in Norway. The are two distinct types of foot-orienteering maps: sprint and forest. Emily has made several sprint and forest maps in Hadeland, Norway and Wiltshire, England.

Foot-O maps are highly detailed and show all vegetation changes, forest runnability, and many point features: depressions, knolls, gullies, boulders, cliffs etc. The scale istypically 1:10000 or 1:15000 in the forest and 1:4000 for sprint maps

Recent works include: Tinney’s Firs and Redlynch, Wiltshire (sprint), Gran (sprint), Lygna (forest) and Omdalsvatnet (forest), Norway.

Ski Orienteering maps

Ski orienteering maps use a foot-orienteering map as a base, usually with paths and tracks removed, and the special green Ski-O symbols added.

Creating Ski-O maps takes time as the course setter must create the trail network from scratch by snowmobile. GPS is used and imported into OCAD to draw the network accurately.
