The “Project of the Month Switzerland” (PotM CH) of April 2022 is about the collection of sustainable offers, i.e. stores and vending machines that are organic, regional, unpackaged, fair trade or second hand, and vegetarian and vegan restaurants as well as food sharing including water refill. Note the relevant tags and keys in the PotM documentation . The “Sustainable” web map  by user ToastHawaii nicely depicts most of the items.
Dashboard and Ranking
The April 2022 PotM-CH dashboard was given the number 19 . As before, it shows a ranked list of the mapper names that have edited the most. By the way, users geo_max and Geonick, currently ranked second and third, are out of contention. So currently imagoiq, sampeto and Necessary_Function are on the first three places.
Prizes and Mapathon/Hackathon 29 April 2022
The April 2022 PotM CH is a very special promotion with prizes to be won: The three most diligent mappers will receive small gift boxes from the farm! The prizes will be awarded at the Mapathon/Hackathon Rapperswil 2022, which will take place next Friday afternoon, April 29 . There are still places available at this Mapathon/Hackathon (“Ask us Anything”).
Sustainability Week Rapperswil 2022
The PotM CH prizes and pizza and drinks from the Mapathon were sponsored by Sustainability Week Rapperswil 2022 (NHWR22). Here is the whole program of the #NHWR22 .
What does “sustainable” mean?
The term “sustainable” has been defined rather restrictively in this PotM. It actually means much more, such as free repair offers, car and bike sharing, or environmentally sound waste disposal. Much of this has already been proposed in the PotM documentation  and could be done in the next months.
Have an idea for a “Project of the Month”?
If you have an idea for a PotM CH, just post it in the documentation/wiki  or get in touch on one of the channels mentioned in the help here .
Now the time has come: The “Project of the Month Switzerland”, short PotM CH, has started! The idea is to work together on a specific OpenStreetMap (OSM) topic. This way, mappers can be made aware of a topic and newcomers to a topic can be introduced to OSM. It is also used for targeted data improvement (“Directed Data Collection”). The idea for this comes from the French “Projet du mois” and the German “Schwerpunkt der Woche”, among others.
Wiki page for PotM CH and PotM CH Dashboard
A wiki page for PotM CH  has now been set up and a PotM CH webapp  implemented. The wiki page explains again what it is about and the PotM CH webapp shows in a dashboard with charts the active mappers and the progress.
PotM CH July 2021 Campsites and RV parks
PotM CH July 2021 is about campgrounds and RV sites. Use the tag “tourism=camp_site” for campgrounds and the tag “tourism=caravan_site” for RV sites. More tips can be found on the wiki page for PotM CH  (in german and french). Important: Always tag changesets with #potmch!
Next actions and StreetComplete and MapComplete
The next actions are already planned and you can participate and suggest further actions or topics! Just edit the mentioned wiki page . If you want to do pioneer work, you can also configure StreetComplete or MapComplete! On the wiki page for PotM CH you can find the corresponding help.

The city of Vevey has published on the Cartoriviera portal the data from a “mobile mapping” survey that took place at the end of last year. The 45 km of Vevey’s road network was covered and images were taken every 3 metres (people and license plates were blurred).
This data is freely available on the Internet https://cartoriviera.ch/rues-vevey, and these images are available for digitisation. Use the following source in the changesets based on this data:
Today we are welcoming the Swiss Federal Office of Topography (swisstopo) to the open data community. After many years of free access for consumers, today, finally, it is providing reusable open government data that can be used to build and enrich new applications and datasets.
This is a high point of a development of open data availability in Switzerland in which the cantons have been leading for many years starting with the Canton Solothurn over a decade ago and is now policy in nearly all of them.
What does this mean for OpenStreetMap?
The most interesting data for us right now is access to swisstopos “swissimage” aerial imagery. This will at last provide us with good coverage in Switzerland’s mountainous regions, something that has been sorely missing from the global orthophoto mosaics.
On Sunday, October 4, 2020, 25 Swiss castles invite you to the 5th National Castles Day. Their gates and drawbridges will then be open from 10 am to 5 pm for a varied program. So – come on in!
The association Wikimedia CH and the Swiss OpenStreetMap association (SOSM) will complement the event with a Swiss Fortresses Day 2020 (Burgentag 2020). Young and old medieval enthusiasts alike are invited to discover a castle ruin on their own. You decide the program yourself. Every castle has a history and many have something mystical about them. And there is often a fireplace nearby. Find out more with the following tips:

The interactive online map of selected castle ruins shows a hand-picked selection of castles in Switzerland that are freely accessible and easy to reach. Depending on the castle, it can be up to one kilometer (i.e. approx. 20 min.) or more away from the nearest public transport stop or parking lot. Please follow the signs and treat nature with respect (e.g. make sure that there is no danger of forest fires in the area, watch out for ticks, don’t leave litter).
The map contains only a small part of the castles and palaces as they are managed in the Castles Project Switzerland. The Castles project links open data directly from the four open data projects OpenStreetMap, Wikipedia, Wikidata and Wikimedia Commons (photos).
The Swiss Burgentag 2020 was initiated by the SOSM association and Wikimedia CH. The event is also kindly supported by the Swiss Castle Association. We thank the association ‘Die Schweizer Schlösser’ for agreeing to link the two action days Swiss Castles Day and Burgentag 2020.
One of the differences between Switzerland and other countries during the pandemic is that hotels have been permitted to stay open. Not all have done so, but there are around 400 that have kept their doors open.
“Bleibtoffen” now has support for displaying both open and closed hotels, and if your establishment is open, or you know of one that is open, please update this information on bleibtoffen.ch.
Update The SotM 2020 will be in Cape Town. We congratulate the team from Southafrica and look forward to the conference next year.
We would like to inform you about some recent developments. Every year the OpenStreetMap community meets at the international conference “State of the Map” (SotM). This year the event will take place in Heidelberg.
Up to two weeks ago no applications for the SotM 2020 event had been received by the SotM working group. In light of that situation we, the HSR Hochschule Rapperswil and the association SOSM, were asked if we could submit a bid, which we have now done.
We see this as an opportunity to expand the Swiss community and to present ourselves as a cosmopolitan host.
Please reserve the 19-21 June 2020. We hope for an active participation, and that some volunteers will contact us as helpers as soon as it is clear which location will win the bid. The decision is expected by the end of September.
