“Mapper in Residence” bei der Stadt Winterthur im November 2023

Pubblicato il da

Stefan Keller von der OST Ostschweizer Fachhochschule und SOSM-Vorstandsmitglied wird “Mapper in Residence” bei der Stadt Winterthur für vier Freitage im November 2023 (*).

Als Mapper in Residence (MiR)…

  • dient er als Bindeglied zwischen einer Organisation – in diesem Fall der Abteilung Geoinformation der Stadt Winterthur – und der OpenStreetMap (OSM) Community.
  • fördert er das Verständnis für OpenStreetMap unter den Mitarbeitenden der Organisation, z.B. durch Veranstaltungen.
  • fördert er die Verbesserung von OpenStreetMap-Inhalten und -Prozessen durch die Community.

Ein:e Mapper in Residence initiiert bzw. stärkt letztlich die Partnerschaft zwischen der Organisation und der OpenStreetMap-Community. Das kleine Projekt ist inspiriert von “The Wikipedian in Residence”.

Stefan Keller wird unter anderem Daten und Prozesse identifizieren und Werkzeuge verbessern und spezifizieren. Dies um mehr offene Daten der Stadt Winterthur in OpenStreetMap zu integrieren und um diese in OpenStreetMap aktuell zu halten. Dies könnte auch zu einer Verbesserung und Erweiterung des “Leitfadens für Dateneigentümer” (**) von 2021 führen.

Benches are a social institution – like OpenStreetMap!

Pubblicato il da

The project of the month Switzerland (PotM CH, see below) from August 2022 is about the registration of benches in OpenStreetMap. Benches are a social facility for young and old – just like OpenStreetMap! A change simply counts as adding or changing from the tag amenity=bench and optionally other tags like color. The data is updated hourly.

A dashboard (no. 23) shows the changes of this PotM CH since the beginning of August. The time period can be adjusted in the filter at the bottom right. To display the benches, one can use standard map style on OSM.org, zooming in all the way. A useful webapp is also the OpenPOIMap.

More information about this PotM CH can be found on this Wiki page, where by the way also own projects (“Challenges”) can be proposed.

P.S. The “Project of the Month Switzerland” (PotM CH) is about working together on a specific OpenStreetMap topic. This way, mappers can be made aware of a topic and/or newcomers to a topic can be introduced to OpenStreetMap. It is also used for targeted data improvement.

Project of the Month Switzerland (PotM CH) April 2022 Sustainable offers

Pubblicato il da

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 [1]. The “Sustainable” web map [2] by user ToastHawaii nicely depicts most of the items.

Dashboard and Ranking

The April 2022 PotM-CH dashboard was given the number 19 [3]. 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 [4]. 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 [5].

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 [2] 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 [1] or get in touch on one of the channels mentioned in the help here [6].

Project of the Month Switzerland (PotM CH) July 2021 Campsites and RV Parks

Pubblicato il da

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 [1] has now been set up and a PotM CH webapp [2] 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 [1] (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 [1]. 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.

Join the PotM CH July 2021 campsites! Who will make it to the podium in July?

Panoramic photos of the streets of Vevey

Pubblicato il da

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:

Use of swisstopo data and products with and in OpenStreetMap

Pubblicato il da

As announced in our previous post, from the beginning of this month (March 2021), geodata and products from Federal Office of Topography (swisstopo) have been available on far less restrictive terms than previously.

As I noted then we didn’t have details available at the time so couldn’t comment further on the use of this data in OSM. In the meantime the terms are available and are limited to an attribution requirement which however applies downstream too. In the case of an use in OSM this would require products using our data to display attribution to swisstopo, this might seem to be an easy to fulfil requirement, but our licence specifically allows use that only credits the overall source of the data (that is the OpenStreetMap project). Considering the 100’s if not 1’000’s of 3rd party sources and 1.6 million individual contributors, this makes a lot of sense. But as a consequence this rules out direct use in OpenStreetMap till we have agreed alternative arrangements with swisstopo.

But it isn’t all gloom and doom, we have already agreed that we can make swisstopos high quality orthophoto product “swissimage” available in OSM editing apps and naturally applications that combine OSM and swisstopo, for example a map with swisstopo derived hill shading, is possible as long as swisstopo is credited.

It will take a bit until configuration updates have reached the major editors, if your favourite one supports custom imagery backgrounds from WMS servers you can add swissimage manually with

https://wms.geo.admin.ch/?FORMAT=image/vnd.jpeg-png8&TRANSPARENT=TRUE&VERSION=1.3.0&SERVICE=WMS&REQUEST=GetMap&LAYERS=ch.swisstopo.images-swissimage&STYLES=&CRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}

the above will work for JOSM, for Vespucci replace {proj} with EPSG:3857. The images are from flights in 2017 to 2020 (Map) in some cases we have access to cantonal imagery that is more recent. Please note that use of swisstopo infrastructure is subject to additional terms of use that should be respected.

Update September 14th 2021: swisstopo has now clarified that central attribution is acceptable for uses that combine many different data sources. See https://www.swisstopo.admin.ch/de/home/meta/konditionen/geodaten/source.html

Welcome swisstopo!

Pubblicato il da

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?

Short term nothing is going to change. While at the time I’m writing this we don’t have access to the final terms of use, we do have a good idea of what the content will be and some of the terms will not be completely compatible with our distribution licence, the ODbL. This rules out direct inclusion in our data, but will allow use as reference data for quality assurance. We are negotiating with swisstopo for compatible access terms, just as we have previously done for the municipality administrative boundaries way back in 2011 and more recently for use of the GWR address data and expect these issues to be resolved soon.

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.
