server outage

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 to umap 0.8

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.

Building Addresses Canton Berne

As you may remember early this year we got permission to use the open address data from the Canton Berne in OpenStreetMap, this after a couple of years back and forth due to the new cantonal legislation and older usage terms that sounded as if the data might be usable but in reality didn’t allow it.

The address data is available from the cantonal open data portal however it is rather unwieldly (a good 400’000 addresses) and problematic to handle even in JOSM. I foolhardly promised to do something about that at the time, but didn’t get around to doing anything up to now. It should be noted that nobody has stepped forward and volunteered to organize an import of any kind, so my focus is simply proving it as reference data that can be used at a small-scale.

While my current solution is not perfect and will likely see improvements over time (for example the layer is currently opaque), it is probably  the best solution for now. I’ve produced a background layer from the data that shows

  • usage
  • house
  • street/place

josm-bern2

 

To reduce clutter I’ve shortened some of the usage strings:

  • Wohnhaus – WH
  • Bauernhaus – BH
  • Garage – G
  • Scheune – S
  • Gebäude – B

The data is hosted on sourcepoles QGIS Cloud system, many thanks to Marco and his team for supporting us. To make things simpler for iD users and work around some issues JOSM has with WMS servers we actually proxy this through our mapproxy instance.

The relevant tile URL is:

Please add a clear indication of the source in your changesets if you use this data.

Translating osm.ch

new_osmch

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.

Wikimedia Germany donates old Toolservers to SOSM

New serversOn 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.

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

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.

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:
