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

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.

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

Missing Crosswalks – A MapRoulette Challenge

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.

Once integrated in OpenStreetMap (OSM), crosswalks are shown in web maps (e.g. OSM Cycle Map/OSM Radfahrerkarte/OpenCycleMap, OSM France and OSM2World). And they are useful for pedestrian navigation apps (like OsmAnd).

So help OpenStreetMap to improve this missing information!

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.

Happy mapping!

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.
