More on map scales


I was poking around Tore Sandvik's newly released web site and came across some discussion of map scales at the World Cup race in Belgium.* Since I wrote about map scales recently (October 15), Sandvik's discussion caught my eye.

Here is a quick (and rough) translation:

The middle distance qualifying race (3,710 meters, 125 meters of climb, 11 controls) was in terrain where the courses went around and over a moraine covered with a mixture of hardwood and spruce forest....Both the courses and terrain were good, and except for the map being at a scale of 1:15,000 and printed in four colors, the map was good. That the IOF decided to use a scale of 1:15,000 instead of 1:10,000 on that map was a scandal....That the IOF chose a scale of 1:15,000 for the map [for the final of the middle distance] wasn't as hopeless, but it is still a scandal that they use anything other than 1:10,000 for a middle distance race.

You can see the map on the web (though you can't really tell how it would look printed at 1:15,000 with four color printing) at the organizer's web page. Check out the page with route choices.

Poking around a bit more, I found a scanned copy of the map . It copied the image onto my computer and resized the image to try to get it to look like a 1:15,000 map (adjusting the image so the distance between the magnetic north lines is 500 meters at 1:15,000). Doing that makes the map quite difficult to read (though it isn't really a fair way to assess the actual competition map).

At least one regular reader of Okansas ran the Belguim World Cup. Kenny, any thoughts about the map and scale of the middle distance qualifying race?

*If you're not familiar with Tore Sandvik, let me give you a bit of info. He's on the Norwegian national team and runs for Halden SK. He got two silver medals at the WOC in 2001 and won a gold in 1999.
