overpass-turbo is an easy to use data mining tool for OpenStreetMap. To reflect the continued improvement of the tool, we have updated this software on the SOSM servers to the latest version. Thanks to Martin Raifer who is the developer of this tool.
routing.osm.ch also got an improvement: Now the link to the debug map works correctly and shows the routing speeds and turn weights used by the currently selected profile.

We had a server outage from Saturday evening June 24th until Monday afternoon June 26th. The main reason was that three disks had failed in the production server and had to be replaced. Fortunately, we had enough spare disks. Sorry for any inconveniences this outage has caused. Everything should be back to normal now.
Update: the old interface is turned off. The new one is available at routing.osm.ch
Why the new interface?
There was no easy way forward. A little background: Last year, we bough some shiny new SSDs to speed up our servers. I decided to install the new Ubuntu 16.04 onto the new disks, the new long term support version. In the mean time, most services are moved to the server with the new Ubuntu and the SSDs, except routing. I couldn’t get our old version of OSRM to run on Ubuntu 16.04, so I was forced to upgrade to the newest version. But a lot was changed in OSRM in the mean time: the API for routing requests as well as the syntax for the routing profiles. That is the main reason why we still run such an old version. The old user interface we used is no longer maintained, therefore incompatible with the current API. But there is a brand new one, which does not support multiple routing profiles. So starting at the hack weekend in Karlsruhe, I hacked the profile selector into the new interface.
The plan is now to switch to the new OSRM and user interface on Sunday, March 19th.
Das ist doch eher selten: Im Moment hängt in Wangen an der Aare ein Plakat, das für OpenStreetMap wirbt. Dies haben wir Roman Härdi und Markus Bubendorf zu verdanken, welche mit Erlaubnis der Chäsi Wangen das Banner am Baugerüst angebracht haben für die Dauer des Umbaus.
Das Banner hatte Roman Härdi drucken lassen nach diesem Design. Es war zuvor auch schon mal am GEOSummit zu sehen.
A new version of umap was released a few weeks ago and we have updated our instance at umap.osm.ch to the newest version. New features include:
- Support for multi polygons
- A new search interface, returning a list of found places instead of going to the most likely one.
- Extended editing: For example polygons can now be converted to lines, or lines can be split into several parts.
- A history of saved states exists, allowing to go back to a previously saved point.
- The map can now be exported with all its properties and be restored on another instance for example.
- And many other things have been improved.
Thank you to Yohan Boniface, who is the main developer, for providing us with such a nice tool.
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).
Our current server is a rented root server located in Germany, because comparable offers in Switzerland are a lot more expensive.
Adfinis SyGroup is now hosting our new servers at their center in Bern. A big thank you to Adfinis for making it possible to run our services in Switzerland!
On Friday we drove 870 km to Haarlem in the vicinity of Amsterdam to pick up three servers. Wikimedia has decommissioned their two year old toolservers and donated the hardware to SOSM. Thanks to Wikimedia Germany and Wikimedia Switzerland for making this possible.
This will enable us to run our services on our own hardware in Switzerland. Support the move by contributing to the SOSM donation drive 2015.
