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 →
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.
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 firstname.lastname@example.org
Update: translations for all aditional languages were done by Friday the 24th of April!
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.
* 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).
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.
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.
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.
Mapping starts 14:00

Data entry etc.
Dinner roughly 18:00 (for those that choose to stay)
One of the lesser known aspects of the Swiss democratic system is the instrument of the “Vernehmlassung”, a formalized call for comments by interested and affected parties on draft laws before they go in to the parliamentary process and debate. The Canton of Berne is implementing new regulations on geo-information and related sovereign duties to be compatible with the equivalent legislation at a federal level and issued such a call for comments late last year.
The tl;dr gist of our answer is that the law should as a principle allow free access to the cantonal geo-data and do so on terms defined in a suitable well-known licence (CC0, PDDL or similar) reversing what is suggested in the current draft legislation. Further we have suggested that any fees for access to the data be based on marginal costs for the distribution.
