Am 8. und 9. Juni findet in Bern wieder die Messe GEOSummit statt. OpenStreetMap ist zwar nicht mit einem eigenen Stand vertreten, aber wir machen dieses Jahr wieder die Aktion, dass wir am GEOSummit wieder Karten aus OSM Daten rendern. Diese werden freundlicherweise von Canon (Schweiz) vor Ort gedruckt. Hier der Bereich, den wir an der Messe anbieten können:
Dieser Ausschnitt ist verfügbar zum Karten rendern am GEOSummit. Der hier gezeigte Stil ist OpenTopoMap.
Wer nun eine schöne, A1 grosse, gedruckte OSM Karte haben möchte, soll doch am GEOSummit beim Stand A05 vorbeikommen. Da der GEOSummit Eintritt kostet, haben wir auch gratis Tickets abzugeben. Wer also eine gedruckte Karte möchte, und dafür ein Ticket benötigt, melde sich bitte bei uns. Der GEOSummit findet in der Bernexpo (Karte) statt.
Weiter werden am GEOSummit auch die druckfrischen A7 OSM-Flyer verteilt.
Objects that were modified or created during the mapping party
Last Saturday, the yearly SOSM AGM and subsequent mapping party took place in St. Gallen. We elected Raphael as our new treasurer during the AGM, since Pascal stepped down from this position and whom we would like to thank again for his work. Philipp was elected as a new revisor to replace Raphael, and Roman as an additional assessor to the board, where he will mainly take care of doing more marketing. Apart from that, there were no further changes regarding the board or revisors. After the OSMF had accepted our application in the beginning of this year, we unanimously decided to sign the local chapters agreement. We will thus soon be in a regulated relationship with the global OSMF.
After a fine lunch, we split up the old town of St. Gallen between us and set out to collect addresses and POIs, and also to update existing data. Along the way, we were also able to enjoy the nice and springlike weather. Some of us met again in the late afternoon to digitise and further improve the collected data, and to talk about experiences and tips related to OpenStreetMap. A remaining, in the meantime rather small group finally went for a cosy dinner in a nearby restaurant to finish the day.
According to a rough estimation based on the Overpass-API, 58 objects have been deleted, 615 were modified and 716 newly added during the mapping party. However, at least Simon had added several buildings before the mapping party already, which are not part of these statistics.
Take part of this MapRoulette Challenge which is about checking if there’s a pedestrian street crossing (crosswalk) or not. This verification goes on until it’s all done. MapRoulette is a kind of gamified website and a mapping campaign similar to MapZen’s targeted editing series.
So help OpenStreetMap to improve this missing information!

A crosswalk node needs to be placed as part of a way. It requires the tag highway=crossing (search for “Crossing” e.g. in built-in online editor “iD”). For the capture of other attributes like the existence of islands or traffic signals see Key:crossing on OSM Wiki.
Important notes: When using editor “iD” the presets suggest tag crossing=zebra. This tag is mainly used in UK. Since this challenge is in Switzerland you can delete this tag. Finally: When saving, a changeset comment is needed. You can use there e.g. “Missing Crosswalks Challenge”.

The street crossings (crosswalks) in fact are coordinates our automated process found in aerial images by using a parallel image detection algorithm. This new software works mainly with yellow crossings of Switzerland on aerial images with certain quality at zoom level 18.
The coordinate data around eastern Switzerland has been extracted at December, 2nd. 2015. This covers about a tenth of the total area of Switzerland.

The first micro mapping party in Zurich took place last Saturday, at very nice and warm weather. The aim of the mapping party was collecting and updating POIs in downtown Zurich, which was already fairly well mapped, but still has … Continue reading →
As part of the move I’ve updated the osm.ch portal a bit and added the
ability to pull translations from transifex. Up to now the portal was
only in German, I’ve added an English version leaving French, Italian
and Romansh to do.
Given that there are currently only 43 strings, I fully expect that we
will have the missing three languages covered tomorrow :-).
On a more serious note we are always looking for people that can help
with the translation of content on sosm.ch which is currently
predominantly German and English. If you want to help send us a mail to email@example.com
Update: translations for all aditional languages were done by Friday the 24th of April!
