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.

#orienteeringMapping #Zürich #OLZürichByNight
OK. Took me a while but I am making progress (yeah!). Below you can see the base map for mapping Zürich as an Orienteering Sprint map. Really can't wait to start mapping.

Today I ran the second part of the green track on Gotska Sandön, Sweden, while checking the autogenerated map to make corrections also for #OpenStreetMap later on. The trail is.... *badumtss* epic.😁

#OrienteeringMapping #GotskaSandön
To keep me from finetuning the autogenerated map any further, I send it to the printer, Media Perret (our 🇨🇭 o-maps Specialist) to print it as it is on Teslin. 5 sheets of A3. Scale 1:11K to fit. 2.5 m contours and 7.5° declination. What I plan is using the maps this summer, then finetune it a bit and then round the project up with a print on two sheets of #Tyvek 50x70cm

Here are the four base maps, I use to get my Sandön Map.
1) 2.5m Karttapullautin contours. 2.5 m, brown positive, purple negative.
2) Hill-shading of the surface
3) 2.5 m TPI contours (Topographical position index). Green positive, red negative.
4) 0.5 m raw contours. Blue if positive, orange for depressions. Every 2.5m a bit thicker.
