2015 SOSM Donation Drive

umap_screenshotDear friends of OpenStreetMap and SOSM

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.

Donations can made to

Postfinance account
IBAN CH54 0900 0000 8505 3542 9

Swiss OpenStreetMap Association
Heitersbergstrasse 1
8962 Bergdietikon

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 info@sosm.ch.

2015 SOSM AGM and Mapping Party, Saturday April 18th 2015 (Updated March 18th)

SOSM  will be holding its 2015 AGM in Bienne/Biel, 11:00 at the Lago Lodge . We intend to follow the same format as previous years: short formal part, lunch and then some mapping. Agenda and venue will be announced by mid March.

Non-SOSM members are welcome, if you want to attend the meeting and/or lunch please send mail to info@sosm.ch since space is likely to be limited.

MapProxy Service Update

We’ve updated the imagery available via the SOSM mapproxy service to include more recent imagery for Solothurn and the recently releast imagery for the city of Berne. The imagery for the canton Solothurn is a mosaic of imagery between 2011 and 2014 provided by the cantonal GIS office SOGIS, replacing the old 2007 and 2011 orthophotos.

Together with the new AGIS imagery, the above has been added to the central OSM imagery index and should be available in iD, P2 and vespucci soon.

If you can’t wait, the imagery is available via the following pseudo URLs:






Updated Aerial Imagery for the Canton Aargau


As already indicated on the Swiss OSM mailing list SOSM has obtained the most recent imagery from the cantonal GIS office of the canton Aargau (AGIS). The imagery was recorded in July 2014 which on the one hand makes it very current, on the other implies that there is more foliage visible than on the 2011 imagery.

The imagery is available with the following pseudo URL for entry in OSM editors


I’ll be adding the configuration to the central imagery repositories as soon as possible.

The tiles from this imagery were produced slightly differently than the previous ones with not quite satisfactory results from a visual point of view. It is possible that I might rerun the tiling later once we have some feedback.

SOSM will be running a donation drive soon to cover the costs of the imagery and a build out of our services, however please feel free to donate now (account details, please indicate if mentioning your name is allowed), your support if very much appreciated.

A thank you to the Hochschule Rapperswil and Stefan Keller for helping us with actually uploading the 190GB of data to the SOSM server.

Our server now supports SSL

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!

We now support SSL on our sites, for example https://umap.osm.ch.

High Resolution Aerial Imagery from the City of Zürich


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.

We hope that this sets yet another example for other Swiss cities and cantons, to open up their WMS servers. SOSM will continue to negotiate with other cantons and cities (see http://sosm.ch/projects/cantonal-aerial-imagery/ for progress).

Many thanks to the GIS office of Zürich!

For P2 and iD users we have added the layer to our mapproxy configuration and it can be accessed (with placeholders) with:

uMap Instance for Switzerland

It has been a long time in the making, but at last, we are happy to announce that a SOSM hosted uMap instance is available: umap.osm.ch .

uMap allows you to create hosted map configurations that contain base maps, data sources and manual annotations.

An example of what can be done with very little effort: the “Swiss style” map with car sharing locations queried from the Overpass API.

See full screen

While the data displayed in the example is static, the same can be done with a direct query of the OverPass API or similar sources. Data that is limited to Switzerland can be retrieved from the SOSM Overpass service, and to make that a bit easier we now have a local Overpass Turbo instance.

To create your own map on umap.osm.ch you simply need an account on www.openstreetmap.org and allow umap.osm.ch access to it.

A special thank you to Sarah for setting up the system for us and to Yohan Boniface for developing uMap.
