I might never become friend with the 1:7.5K. The downsides are obvious.
1) The legs fall apart into a series of details
2) The terrain is no longer depicted fairly good resp. also falls apart.

The reason for both simply is, that symobls, object density and eqidistance where optimized to fit a certain scale. Blowing everything up does not work.

[For the rest, the course and terrain were great]

Looking for some holiday goals I stumbled over this one. 😍

Of all competitors of M50 at the 2026 Sprint Orienteeering Championships in #Lausanne
To the 8th control, one athlete (Niggli) runs in 31 seconds. The second (Plattner) in 37, the third in 50, the tenth in 55, the 20th 68 seconds.

It thus looks like only 2! of 39 were able to find the by far best solution.

IMO a clear indication of an irregular task presentation...

Well, the Swiss Champs in Sprint Orienteering yesterday in #Lausanne were fun.
[A bit too short for my taste :-P, and also a bit too tricky. I like it when route choices are complex, but I don’t like it when simply understanding the task becomes the main challenge because of overly complex and illegible mapping. Check out the attached samples.]

Next Sunday, the Swiss Champs in Sprint Orienteering are held in Lausanne.

Usually I don't prepare for orienteering, but I somehow stumbled into this one. 😛
The old town of Lausanne with its complex relief, stairs and tunnels invites to a very complex challenge. To mitigate that, I took ten minutes to wrap my head around the topography of the venue.

Looks like fun ahead...

The recent Training for Orienteering Mapping beginners triggered some reflection process, how my own setup looked like if I would actually work with the OCAD app (and solely used OCAD Desktop to build the Field Set). Check out the descrption.

Ok. Round four for the annual Swiss Orienteering Mappers Beginner training in #Sursee.
My room got upgraded this year, such as I got this direct view on the training area (Haselwarten Wald).
Rare occasion for mapping from bed.😎🤣

I am preparing a training for new orienteering mappers to be held next weekend. Reluctant to the AI I am I could not help to generate this picture to depict the relationship between new mappers and the ISOM (International Specification for Orienteering Maps). I will introduce the later as the product of a slightly disappointed father who was hoping he could prevent his kids from making the same mistakes he did in his own mappers youth. :-P

Last autumn, we invited our top mappers to spend a single day mapping a small forest near Sursee (LU), Switzerland. The forest is a typical Mittelland example—nothing spectacular, but full of the usual challenges around generalisation (point features) and vegetation classification.

Now at the Annual Swiss Orienteering Convention in Olten, Mark Gloor presented the results of this experiment.

Check out his slides:

Gestern lief ich meinen ersten Indoor-OL anlässlich dem 2. Zürcher Indoor OL im Gebäude de ZHDK, Toni Areal.
Das war soooo geil.🤩 Such a thrill (43 Min. full speed few mistakes)

Angehängt die beiden Laufkarten (try it). Geile Bahnen über 8! Etagen und Karten nach dem aktuellen Draft der ISInOM (neue internationale Indoor Norm) durch Peter Grau und Janine Dünner von der OLG ZH.
