Auch wenn wir von der am meist diskutierten vorgeschlagene Änderung, die “Linksteuer” nicht direkt betroffen wären, scheint es uns nicht sinnvoll Regelungen einzuführen die, zugunsten von einzelnen Unternehmungen, versuchen die Zeit zurück zudrehen, und in diesem spezifischen Fall auch noch handwerklich katastrophal sind.
Die weniger besprochene weitere Änderung, die Einführung eines Äquivalents des Lichtbildschutz, den wir aus anderen europäischen Ländern kennen, betrifft uns aber direkt.
Bisher hatte die Schweiz eine sehr hohe Hürde, die überwunden werden musste um einen urheberrechtlichen Schutz einer Fotographie zu erhalten (Bundesgerichtsurteil “Meili Foto” ). Dies wird nun ins Gegenteil gekehrt, mit dem Resultat, dass man davon ausgehen muss, dass auch automatisch und mechanisch aufgenommene Bilder in Zukunft geschützt sind (also Luftbilder, StreetView, Mapillary und so weiter) und ebenso daraus abgeleitete Werke nur noch mit der Erlaubnis des jeweiligen Rechteinhabers erstellt werden dürfen. Der Bundesrat schliesst dies zwar in seiner Botschaft zur Revision aus, der Gesetzestext selber scheint aber dazu im Widerspruch zu stehen.
Auf jeden Fall ist die Rechtssicherheit für uns bei der Benutzung solcher Quellen nicht mehr vorhanden, was nicht in unserem Interesse sein kann.
OpenSchoolMaps.ch is a new initiative to promote open maps in geography and computer science lessons in Switzerland. Teachers at secondary and grammar school level are the main target groups. To all who know teachers in geography and computer science: Pass this news on, www.openschoolmaps.ch!
Both the maps (data) and the materials are made freely available (so-called “Open Educational Resource”), so that everyone can contribute to them, use them freely and pass them on – even outside the classroom. Mainly free data from OpenStreetMap is used.
This small project was initiated by Stefan Keller, SOSM board member and professor at the Geometa Lab of the HSR. It fits to the two focal points, school and tourism, which the association has set itself this year. The SOSM also owns the web domains openschoolmaps.ch and openschoolmaps.org.
The content on OpenSchoolMaps.ch is just the beginning. We are looking for contributors who want to take part in the project, be it with feedback, translations or software tools. Interested parties can contact the project managers as described under OpenSchoolMaps.ch > “Weitere Unterrichtsideen”.
We are now offering a download of pre rendered tiles up to zoom level 17 on https://tile.osm.ch/tiles.html. The tiles are split up into the cantons as the whole of Switzerland is quite a large amount of Data.
You can download them to either host them yourself, or use them in an offline application.
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.
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
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 sourcepolesQGIS 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.
Take part of this MapRoulette Challenge which is about checking if there’s a pedestrian street crossing (crosswalk) or not. This verification goes on until it’s all done. MapRoulette is a kind of gamified website and a mapping campaign similar to MapZen’s targeted editing series.
So help OpenStreetMap to improve this missing information!
Figure 1: Cycle map from OpenStreetMap main page showing pedestrian street crossings (crosswalks) as yellow dot markers.
A crosswalk node needs to be placed as part of a way. It requires the tag highway=crossing (search for “Crossing” e.g. in built-in online editor “iD”). For the capture of other attributes like the existence of islands or traffic signals see Key:crossing on OSM Wiki.
Important notes: When using editor “iD” the presets suggest tag crossing=zebra. This tag is mainly used in UK. Since this challenge is in Switzerland you can delete this tag. Finally: When saving, a changeset comment is needed. You can use there e.g. “Missing Crosswalks Challenge”.

The street crossings (crosswalks) in fact are coordinates our automated process found in aerial images by using a parallel image detection algorithm. This new software works mainly with yellow crossings of Switzerland on aerial images with certain quality at zoom level 18.
The coordinate data around eastern Switzerland has been extracted at December, 2nd. 2015. This covers about a tenth of the total area of Switzerland.
