Since almost two years we offer encrypted access to our services. Back then we bought a certificate for two years, which will soon run out. But fortunately, since this year, there is Let’s Encrypt which provides certificates for free. I’m happy to announce that we have successfully switched and are now able to provide encrypted, secure access without additional costs to the association (except the few days of time spent setting it up).

Micromapping Party Zurich 2015

This gallery contains 6 photos.
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
OpenTopoMap background layer on umap.osm.ch
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.
Translating osm.ch
Thanks to efforts of Michael (datendelphin) the move of the SOSM
provided services to the new SOSM servers in Bern is nearly complete.
See http://sosm.ch/wikimedia-donates-old-toolservers-to-sosm/ and
http://sosm.ch/adfinis-offers-hosting-location/
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
https://www.transifex.com/projects/p/osmch/
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
board@sosm.ch
Update: translations for all aditional languages were done by Friday the 24th of April!
Just 20’000 left to go …
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 | % | |
|---|---|---|---|---|---|
| Roads | 121’041 | 62’258 | 87’759 | 100’012 | 83% |
| Other | 63’673 | 14’101 | 8’598 | 12’465 | 20% |
* 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.

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!
Using the imagery in your editor
For JOSM users the WMS server can be queried with
http://www.gis.stadt-zuerich.ch/maps/services/wms/WMS-ZH-STZH-OGD/MapServer/WMSServer
For P2 and iD users we have added the layer to our mapproxy configuration and it can be accessed (with placeholders) with:
P2: http://mapproxy.sosm.ch:8080/tiles/zh_luftbild2011/EPSG900913/$z/$x/$y.png?origin=nw

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.
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.
Mapping Party Burgdorf April 5th 13:30
As already announced we will be going out and mapping after the SOSM AGM on Saturday and after we have had lunch (please feel free to join us for that too).
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.
Rough schedule:
- Meetup 13:30
- Mapping starts 14:00
- Back at Restaurant 16:00
- Data entry etc.
- Dinner roughly 18:00 (for those that choose to stay)
