Rogaining maps

Map standards considerably less advanced compared to orienteering maps

IRF standards for championship rogaines scale 1:25000 – 1:50000 contour interval ≤ 20 m magnetic north lines at least four color printing

Rogaining maps in Estonia

More detailed compared to the Estonian base map More generalised compared to orienteering maps

Estonian rogaining map style simplified o-map scale 1:30000 – 1:50000 contour interval 5 m

beyond rogaining events, rogaining maps have been used at adventure races and as a base map for drawing MTBO maps

Two methods for preparing the base map for field work

Taking the Estonian base map as the basis, adding information from o-maps, ortophotos and other sources

Taking o-maps as the basis, deleting unneccesary information

Both methods have their advantages and disadvantages

Rogaining map symbols

Rogaining map symbols

Runnability of forest and open areas not indicated No intermediate contour lines or index contours Major, high voltage power lines indicated Single objects depending on terrain

buildings, ruins towers significant boulder clusters single large boulders with height over 2 m major fodder racks

Field work for rogaining maps

Changes to the situation new clearings new building missing roads, tracks, ditches etc

Checking and correcting the road/track/path classes

Correcting contours in particular outside areas covered by o-maps

Unifying the level of generalisation Out-of-bound areas Negotiations with land owners

Amount of time spent

Depends on the quality of base map

1 km² of rogaining map about 1 hour of field work about 1 hour map drawing with OCAD + 5-30 minutes with each land owner

Amount of time per km² rather small compared to o-maps, but the area is large for 24 hour rogaine about 250 km² or 500 hours for 8 hour rogaine over 80 km² or 160 hours

Printing of rogaining maps

Large quantities, single course for TAOK rogaines over 1000

Offset printing from 2007 onwards TAOK rogaine

competition maps printed on PolyArt water- and tearresistance plastic

enamelled paper maps for course planning
