Building addresses of canton Bern

Like Simon has already noted in a previous blog entry, we may use the Building Addresses of the Canton of Bern (GEBADR) for OSM.

In the last months the data was prepared to be suitable for OSM and a tasking manager was set up. Further information can be found in the documentation on the OSM wiki about this project.

Some are already mapping the addresses and are drawing the missing building outlines. But the task is rather large with a total of 400’000 addresses and it will take a long time. Further mappers supporting this project would therefore be really welcome. So please spread the word!

A special thank to Michael Spreng for his support and setting up the tasking manager. The tasking manager was set up on the servers of SOSM and is now available for other projects as well.

Pre-announcement: 2017 SOSM AGM, April the 8th in Fribourg

The 2017 SOSM annual general meeting will take place on April the 8th in Fribourg, venue to be determined.

We will likely keep the format from the previous events: formal meeting before lunch, lunch, mapping and back to the venue.

If you have suggestions for or contacts with a suitable venue please get back to me.

The formal announcement will be published towards the end of March.

Looking forward to seeing you in Fribourg.

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.

SOSM is now an OSMF Local Chapter

When we founded SOSM in June 2012 one of the topics was if we should aspire to becoming a formal local chapter of the OSMF. At the time it wasn’t urgent since the OSMF hadn’t actually finalised a template agreement or actually accepted a local chapter, it took nearly another 3 years for the first chapter to be admitted (Iceland early in 2015).

In 2012 and every time we had discussed the matter at an AGM the SOSM board had made clear that we would hold a members vote when the time was ripe and that took place at our AGM in April of this year. Still even with the approval of our members it has taken us another 5 months to actually get the agreement signed at the global State of the Map conference last week.

We don’t expect any drastic change with this step, however given that so much of our work deals with government offices, political and other advocacy groups, having “official” status cannot hurt. The other part of the equation is that the agreement gives us a formal licence to use OpenStreetMap and other related trademarks in Switzerland.

Looking forward we expect to see more collaboration with other local chapters going forward and expect them to grow in importance as stakeholders in the project.

https certificate now provided by Let’s Encrypt

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).

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.

Kartendruck am GEOSummit 2016 in Bern

Am 8. und 9. Juni findet in Bern wieder die Messe GEOSummit statt. OpenStreetMap ist zwar nicht mit einem eigenen Stand vertreten, aber wir machen dieses Jahr wieder die Aktion, dass wir am GEOSummit wieder Karten aus OSM Daten rendern. Diese werden freundlicherweise von Canon (Schweiz) vor Ort gedruckt. Hier der Bereich, den wir an der Messe anbieten können:

extent-small

Dieser Ausschnitt ist verfügbar zum Karten rendern am GEOSummit. Der hier gezeigte Stil ist OpenTopoMap.

Wir haben den OSM Standard, Swiss Style und auch OpenTopoMap Kartenstile im Angebot.

Wer nun eine schöne, A1 grosse, gedruckte OSM Karte haben möchte, soll doch am GEOSummit beim Stand A05 vorbeikommeOSM_flyer_CH2016rh-frontn. Da der GEOSummit Eintritt kostet, haben wir auch gratis Tickets abzugeben. Wer also eine gedruckte Karte möchte, und dafür ein Ticket benötigt, melde sich bitte bei uns. Der GEOSummit findet in der Bernexpo (Karte) statt.

Weiter werden am GEOSummit auch die druckfrischen A7 OSM-Flyer verteilt.

Aktive Mapper können gerne ein paar holen kommen.

Report from the SOSM AGM and Mapping Party in St. Gallen

Achavi view of objects that were modified or created during the mapping party

Objects that were modified or created during the mapping party

Last Saturday, the yearly SOSM AGM and subsequent mapping party took place in St. Gallen. We elected Raphael as our new treasurer during the AGM, since Pascal stepped down from this position and whom we would like to thank again for his work. Philipp was elected as a new revisor to replace Raphael, and Roman as an additional assessor to the board, where he will mainly take care of doing more marketing. Apart from that, there were no further changes regarding the board or revisors. After the OSMF had accepted our application in the beginning of this year, we unanimously decided to sign the local chapters agreement. We will thus soon be in a regulated relationship with the global OSMF.

After a fine lunch, we split up the old town of St. Gallen between us and set out to collect addresses and POIs, and also to update existing data. Along the way, we were also able to enjoy the nice and springlike weather. Some of us met again in the late afternoon to digitise and further improve the collected data, and to talk about experiences and tips related to OpenStreetMap. A remaining, in the meantime rather small group finally went for a cosy dinner in a nearby restaurant to finish the day.

According to a rough estimation based on the Overpass-API, 58 objects have been deleted, 615 were modified and 716 newly added during the mapping party. However, at least Simon had added several buildings before the mapping party already, which are not part of these statistics.

Mapping Party St. Gallen April 2nd 2016

View of St. Gallen

After the SOSM AGM we will have our traditional post-AGM mapping party. This time we will concentrate on improving the mapping of St. Gallen the 8th largest city in Switzerland.

As always everybody is invited to come, including joining us for lunch at 12:00 at the Hotel Am Spisertor, Moosbruggstrasse 1, 9000 St. Gallen.

If you intend to join us for lunch please send us a short note at info@sosm.ch
