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.
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.

As you may know, SOSM provides a range of services for the Swiss OpenStreetMap community. Currently this is financed for a major part out of our regular membership fees, this however limits some aspects of our operations quite considerably. All services are currently run on a single, small leased server in Germany.
In 2015 we would like to
move all services to a hosting location in Switzerland
provide better performing and redundant hardware for our most popular services (map tiles, uMap and routing)
expand our OSM data and imagery hosting offerings (for example the current imagery covering the Canton Aargau)
While we have the prospect of a number of in-kind donations to support the above, more on that soon, there is still the need for additional funds to cover cash outlays. Example: while we have a computer hardware donation arranged, the hardware will have to be imported and VAT on its value paid, just this single item would be substantially outside of SOSMs current annual budget.
To support the plans for this year SOSM board has therefore decided to explicitly ask for donations to SOSM in 2015 with the goal of collecting at least CHF 5000 over the course of the year.

Please note 2015 DONATION DRIVE on the payment. By default we will be publishing the names of all donors, if you don’t want to be mentioned, please add that either to you payment information or send mail to firstname.lastname@example.org.
Our new umap service made quite a good start. We had quite positive feedback from several people. But there was also a problem reported by Adfinis SyGroup: They added a map to their home page using umap. Now when the homepage is was with SSL the browser denied the embedding of umap which was without SSL (known as mixed content blocking). And not only did they make us aware of the problem, they even offered to pay for the necessary SSL certificate. Thank you for sponsoring the certificate!
A couple of weeks back the city of Zürich expanded the available layers on its public WMS server to include areal imagery of the city from multiple years. Of particular interest to us is the 2011 data which is clearly superior to what has been available up to now and is a lot better georeferenced. This will allow us to address some of the issues we have in central Zürich and is a huge leap forward from the Bing/Yahoo imagery we’ve had until now.
