		<description><![CDATA[@WOC Runner: I agree with many of the views posted here, in particular I think that we should have realized at least 2-3 years ago that with big screen GPS tracking there is really no need for arena passages!

I.e. when the terrain is suited for it, with good forest on both sides of a relatively short arena passage that is the only way to link them, then by all means use such a passage, but otherwise keep the orienteers in the forest, orienteering.

I was indeed involved with JWOC 2015 from the very start: I developed all the base maps for both competition and training maps, so map (and course) quality is what I&#039;m most concerned about.

To me there are just a few crucial issues:

At which scale is the map readable? If the terrain is too complicated to allow even a master mapper to depict it according to the ISOM standard while maintaining at-speed readability, then I personally believe we should allow enlargements instead of stating categorically that &quot;such terrain is unsuitable&quot;. Generalization is still crucial but Shannon&#039;s Sampling theorem still applies: We cannot simplify/generalize so much that the actual terrain disappears.

Making an orienteering map is really an exercise in compression - we&#039;re trying to convey the maximum amount of useful information in the smallest possible amount of ink. :-)

Is the mapping fair? Unless the map makes it at least possible (it might be very hard!) for runners to determine the best routes, then we introduce a large element random chance. 

I believe the great 2nd leg of WOC Long might be in this category simply because it came before the runners had any time to experience both the terrain and the mapping, otoh I also believe these courses will win the end-of-year voting on the best Long distance courses of 2016.

As TG complained, there should have been model maps of similar terrain, developed by the same mappers available to the competitors before each event.]]></description>
