7.6.1 Use of foot-o symbols

The symbols for 1:15 000 foot orienteering maps, scaled to 1:5 000 and enlarged by 100% apply, with the following amendments.

Major amendments

Symbols 406 and 407 are deleted, symbols 405 and 408-410 are re-described:

 
405 Forest: good visibility footo Typically open forest with good visibility of terrain features from the trails
408 Forest: reduced visibility footo Areas with denser trees giving significantly reduced visibility and preventing more distant terrain features from being used as control sites
409 Undergrowth: reduced visibility footo Areas with denser and taller undergrowth giving significantly reduced visibility and preventing lower terrain features from being used as control sites
410 Vegetation: severely reduced visibility footo Areas of very dense trees or undergrowth giving severely reduced visibility

Minor amendments

The following are re-described foot orienteering map symbols indicating appearance and not runnability:

7.6.2 Discipline-specific symbols

Note: dimensions are specified in mm at the scale of 1:15 000.
All drawings are at 1:7 500 for clarity only.
Two new symbols are introduced to indicate passability of the trails for disabled competitors

831 Passable step

A natural or man-made step or difficult section of trail that is passable by disabled competitors with care and assistance. The symbol is a cross line across the trail.
Colour: black.

832 Impassable step

A step or section of trail that is unlikely to be passable by disabled competitors, even with assistance. The symbol is a cross line across the trail.
Colour: black.
