The designers and operators of OpenTopoMap have been kind enough to allow us to include it as a background layer in umap.osm.ch Please note that the maximum zoom level for this layer is limited to 16.
Thanks to efforts of Michael (datendelphin) the move of the SOSM
provided services to the new SOSM servers in Bern is nearly complete.
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.
The transifex project can be found here
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
Update: translations for all aditional languages were done by Friday the 24th of April!
Two years and a couple of months back I started running daily street name completeness checks for Switzerland. See my original article for more information, information on the changes for 2014 (this article points out some of the quality issues with the GWR) and http://qa.poole.ch/ch-roads/ for the daily updates.
On the 12th of March we passed the 100’000 street name mark implying that in 27 months we have added nearly 40’000 names that were previously missing or unverified, leaving roughly 20’000 to go.
|GWR 2014-12-01*||OSM 2012-11-01||OSM 2013-12-27||OSM 2015-03-12||%|
* the GWR values are corrected for the issues discussed in the December 2013 blog post and are not the raw numbers. This is the reason for the decrease in numbers of non-road objects.
Naturally I do not expect to reach the 100% mark any time soon. There is quite a high number of municipalities that do not sign post their roads, making independent verification very difficult to impossible (this is not the same as not having street names in the first place which is not a problem) and naturally these places don’t tend to be where hot spots of OSM contributors are. On the other hand there is still a lot of very low hanging fruit which simply needs verification. Low hanging in this case means that the roads in question can already be found in OSM, but there are simply spelling differences that we need to investigate (see the original article on how to handle differences between the GWR and reality).
Please don’t forget the 2015 SOSM Donation Drive to enable us to continue to operate this and other services.
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:
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.
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.
Meeting location: Restaurant Schützenhaus, Wynigenstrasse 13, Burgdorf
Burgdorf itself is fairly well mapped with only a few roads missing and a handful of name spellings that need to be verified http://qa.poole.ch/ch-roads/BE/404.html . However the surroundings, in particular Kirchberg are fairly undermapped. Kirchberg can easily be reached by Bus, the rest of the villages likely will require a bicycle or other means of transport.
One of the lesser known aspects of the Swiss democratic system is the instrument of the “Vernehmlassung”, a formalized call for comments by interested and affected parties on draft laws before they go in to the parliamentary process and debate. The Canton of Berne is implementing new regulations on geo-information and related sovereign duties to be compatible with the equivalent legislation at a federal level and issued such a call for comments late last year.
The tl;dr gist of our answer is that the law should as a principle allow free access to the cantonal geo-data and do so on terms defined in a suitable well-known licence (CC0, PDDL or similar) reversing what is suggested in the current draft legislation. Further we have suggested that any fees for access to the data be based on marginal costs for the distribution.
Our full answer can be found here Kanton Bern geoinf Vernehmlassung. Opendata.ch, the Swiss OpenData Association, supports our position.
The 2014 Annual General Meeting of the Swiss OpenStreetMap Association which will take place on Saturday, April 5th 2014, 11am in the Restaurant Schützenhaus, Wynigenstrasse 13, Burgdorf
You will find the full agenda here.
After the meeting there will be an informal lunch and a mapping party. If you already know that you will be attending, could you please indicate so for planning purposes by e-mail to firstname.lastname@example.org
We hope to see many of you in Burgdorf.
At the last SOSM board meeting we had a short discussion about membership levels and what kind of numbers that we should expect. The discussion led to two actions, on the one hand we decided that we would, as an experiment, mail all new contributors with a short welcome mail, and on the other hand it piqued my curiosity how many contributors we have historically had and what the current growth rates are (having the numbers handy tends to help when talking to the media too).
The last time I generated overall contributor numbers for Switzerland was a good two years ago and was then at over 6’000, the current number is just over 9’000. The value was generated from a full history extract of Switzerland from November 2013, further inspection of the extract shows that the oldest node in Switzerland was added on August the 15th, 2005. There may have been older anonymous contributions or contributions that were removed during the licence change, but this is the best date we have. This would indicate a growth rate of over 1’000 contributors per year, this number seems to be further supported by the 104 welcome mails we have sent to new mappers over the last 4 weeks.
Naturally Switzerland has a certain influx of non-domestic mappers, on the one hand due to neighbouring countries with strong OSM communities, on the other hand due to its popularity as a tourist destination. But as we know from a pure count point of view, larger, mobile mappers are a small minority and shouldn’t effect the above numbers significantly.
Just over a year ago I started running daily street name completeness checks for Switzerland based on a list of street names by municipality generated out of the federal “Gebäude und Wohnungsregister” (GWR), see my original article for more information and http://qa.poole.ch/ch-roads/ for the daily updates.
For technical reasons I decided to move the contents to a new server late December and during the process I’ve made a couple of updates and changes that need some explaining. On the one hand I’ve updated the GWR list to the December 2013 one on the other hand I’ve somewhat changed the logic of the road (contrary to other object types with names) statistic generation. One of the more annoying trends in the GWR list is that more and more municipalities are no longer correctly filing the object type in their submissions and are either using “unknown” or leaving the field empty (which I map to “none” in my statistics”), despite the large amount of building going on, the number has actually gone down in absolute terms by roughly 500 over the year 2013. This naturally makes the data substantially less useful for us, and I would go as far as saying it makes the data less useful for its primary purpose too.
However it is clearly not our job to discipline such behaviour, we just want as good as possible estimates of how many named streets there actually are. To achieve that I’ve now added some heuristics to take this undesirable behaviour in to account:
The GWR numbers reported are corrected correspondingly. As of today this reduced the object count for “unknown” by 8’374 and for no object type by 4’438, adding a total of 12’812 to the GWR road count. For continuity and documentation purposes the old statistics are still calculated daily and are still available.
More interesting than the above changes is how much progress we have made over the past year. In the following table non-road objects are summarised in one number.
|GWR 2012-06-01||OSM 2012-11-01||%||GWR 2013-12-01||OSM 2013-12-27||%|
As can be seen from the above we managed to add 20’024 names in just over a year, confirming that we should have as good as possible coverage of street names latest in two years.
To conclude, and most impressive, a map from early 2013, and current versions using the old and new logic
