Selection dynamics since 1999

 fig.2 The end of a loooooong career.

I updated the chart with the selection dynamics since 1999.

Modifying the rules
Last year o-zeugs defined a set of unwritten rules describing the selection dynamics for the 2013 mens team and some prognoses where made. Martin Hubmann and Florian Schneider got their upgrades and Andreas Kyburz broke rule 2 (while rule 3 was wrong from the beginning). Here are the modified rules in recent mens selection history:
  1. No runner, not directly upgraded from the junior team to the senior team made it into the senior team later on. (unchanged)
  2. No athlete which did not made it into the U-23 (=under the frist three years as a senior) was later upgraded into the A-team (modified)
  3. (omitted)
  4. The lastest chance to make it into the A-team is after the fifth season. (unchanged)
  5. To directly make it into the U-23, you have to win a JWOC medal. (unchanged)

We are family

  • Bettina and Marion Aebi
  • Paula, Lilly and Julia Gross
  • Matthias and Andreas Kyburz
  • Daniel and Martin Hubmann
  • Mjriam and Sven Hellmüller
We have family (athletes having family members which formerly where selected)
  • Ines Brodmann,
  • Rahel Friederich
  • Laura Diener
  • Florian Howald
  • Yves Aschwanden
  • Joël Borner
  • Thomas Curiger
not sure about: Judith Wyder, Sarina Jenzer

World Cup 1986 Sweden

I got the map from the World Cup 1986 Sweden /Fjärås from okansas.

So the collection of World Cup maps form 1986 is now complete.

Mappers Blog: The JEC 2013 long distance map


fig.1. Excerpt of the JEC 2013 Long Distance Map "Les Hautes Gouttes" by Radim Ondracek, Petr Matula, Zdenek Lenhart, Ivo Haban and JB Bourrin.

Many big names on this map but still a lot more small bushes. :-P This is what Ivo calls the Brno -school.

Mappers Blog: Field notes of Urs Steiner


fig.1. La Givrine 2011. Base Map (1m contours, index contours, vegetation and some details from the aerial image (wall, track)). Field note (naturalistic but blue for 406 and green for 408, no eraser but pencil for the "final line", cross for stones,..). Steiner mapped this map for the WOC 2012 Middle Distance Final. Before the WOC the map was revisioned (fig.2.).
fig.2. Differences between the maps Givrine 2011 and WOC 2012.
The last revision had three main issues: the threshold for undergrowth (407/409) was raised. Some clearances where added or altered (near control points). Top and bottom-features (112 small knoll, 115 small depression) where replaced by equivalent contour-line features.

Running over settlement II

Unfortunately our system doesn’t save (or send) HDOP etc. values. Only figure to use here is number of satellites and on those occasions it has been 7-8, same level as on the other parts of course. In my opinion can’t say based on that track with required certainty that she was in the forbidden area.

Running over settlement

Here is an example of a case of a runner running over settlement area according to the GPS-tracking. The jury decided to not disqualify her.

fig.1. The runners route according to the Live-GPS-Track
fig.2. After the race, the runner is asked about it and sooner published the route she was running (here in red)

And commented:
Och så till min GPS-rutt som har skapat lite problem. På bilden nedan är GPS:en och i rött hur jag anser att jag har sprungit. Jag har dock inte så jättemånga minnesbilder från det här partiet av banan. När jag har flyt, full koll och hela tiden vet var jag är och vart jag ska brukar jag inte komma i håg så mycket efteråt. Jag vet ju hur jag har sprungit men jag kommer oftast inte ihåg hur det såg ut eller vad jag tänkte. Däremot när jag är osäker, inte har riktig koll eller gör misstag, då kommer jag oftast ihåg exakt hur det såg ut och vad jag tänkte. Lite dålig egenskap kanske eftersom det gör det betydligt lättare att ta med sig dåliga saker än bra saker. I det här fallet hade jag väldigt bra koll, jag kommer dock ihåg att jag tänkte springa upp precis efter branten vid huset men fortsatte för att det såg bökigt ut (ändrad plan, ur fokus = tydligt minne). Jag har också två korta minnesbilder av när jag viker av kraftledningen till stigen och att jag senare spanar tillbaka mot kraftledningen för att se så att jag håller lagom avstånd. Så här i efterhand var det ju väldigt onödigt av mig att ta det här vägvalet speciellt eftersom det inte ens var särskilt bra. Arrangörerna hade inte någon tanke på att någon skulle välja att springa där och enligt dem var det också sämre gps-täckning i just det området. Så om nu ingen har manipulerat mitt minne drar jag slutsatsen att jag inte har sprungit på någon tomtmark.
So she explains the difference between the GPS-track and her reality with "locally bad signal coverage".

Protest
The team of another runner protested against the runners classification, but the protest was neglected.
2013-09-29 kl. 13.50
Tävlingsledningen för stafett-SM 2013 har beslutat att det inte har begåtts något fel efter GPS-trackingen för D21. Detta efter att karta har studerats och konferering med banläggare, tomten är en naturtomt, diffust markerad i natur med mycket sly. En del av tomten har markerats i natur men inte vid det specifika området.

Tävlingsledarna:
Christer Westberg, IFK Göteborg
Cecilia Groth, Kungälvs OK


2013-09-29 kl. 13.52
PROTEST
GMOK har protesterat mot tävlingsledningens beslut att fria Tove Alexanderssons löpväg genom/över tomtmark till första kontrollen på str. 3 i SM-stafetten 2013.

Jurybeslut 
PROTESTEN AVSLÅS!
Löparens beskrivning av hur och var hon sprungit efter tomten stämmer överens med att GPS-trackingen förskjutits ca 30 m i syd-sydostlig riktning. Trots att GPS i andra delar av banan varit mycket säker så kan den i denna dalgång i närheten av kraftledning ha en osäker visning. Det enda argument som GMOK framfört till juryn är att GPS-trackingen visar passage av tomtmark.

Some comments on this
1)The quality of the GPS positioning depends on the number and distribution of the satellites the GPS receiver can connect to. The number of satellites available in a given area to a given time is basically defined by the local horizon. The horizon in the area in question shows no significant differences or specialties relative to the rest of the competition area. No slope, no deep valley, no cliffs.
2) Looking on the entire track of this runner, the positioning is working with a good precision (controlpoint and tracks as reference) from the start to just in front of the settlement area and just after the settlement area into the finish.
3) The map is based on laser-data and therefore fully georeferenced. The gps-track shows a good accordance with the map. The track avoids unnecessary climbs and buildings or rockfaces.
4) The calculated speed on the gps-track shows a high accordance to the terrain (faster when on the plain, slower uphill and crossing the trench). Additionally the gps-track show no "jumps" to catch up to the right position.
fig.3. Paceview of the gps-track  (Quickroute)

5) The density of position-points is according to the rest of the track
6) The track according to the runner bends to the right, where as the gps-track bends to the left. (Similar behaviour was screened from Tiomila 2011, ex. 2 path passing lake, several runners track show this error)
7) It is not likely, that the powerline influences the position accuracy (->read this)


The KanPas Focus 200

So here is the KanPas Focus 200. Actually the compass making orienteering easy. Maybe even too easy? - Sorry for that. fig.1. What a beauty ...
