State of the Map Asia 2017 took place in Kathmandu last weekend (23-24 Sep 2017). 1


  • Pierre Béland tweets his analyses on OSM Contributors profiles vs Contributions (ie objects edited) based on the HDYC changesets classification.
  • Ciarán Staunton wonders why the Bing Imagery in southern Africa has suddenly been re-aligned. A Microsoft employee makes it clear that the new images have not yet been adjusted to the offset
  • Williaug GC initiates a discussion on the tagging mailing list with the question, whether shop=door should be replaced by craft=window_construction.
  • Mark Bradley asks in the Tagging mailing list on how to tag “agricultural centers”. Discussion ensues as there are multiple aspects to be considered.
  • Ilya Zverev shares a proposal for Metro Mapping, with a hope to have a uniform way of mapping these features. Comments welcome.
  • On the Tagging mailing list, SwiftFast proposes the tags slogan=* for slogans and logo=* for links to a company’s logo on Wikimedia Commons. Discussion threads: slogan, logo.
  • Simon Poole asks for opinions about the use of the tags shop=appliance vs shop=electronics.
  • Selfish Seahorse started the discussion about swimming pool facilities mapping to clarify the tagging of the various cases.
  • “westnordost” (the person behind the StreetComplete mobile phone app) started a discussion (de) (automatic translation) about tagging cycleway where cyclists can go in both directions on a street that is oneway to motor vehicles.
  • Maripo published a new JOSM plugin “EasyPresets”, which helps with easy creation of your own personal tagging presets.
  • Leigh Dodds writes about mapping wheelchair accessibility in the centre of Bath.
  • Osmose checks now, whether maxspeed=* and source: maxspeed=* match and complains about e. g. maxspeed=30 in combination with source:maxspeed=DE:urban, because 50 km/h are allowed in Germany.
  • User erkinalp proposes a new tagging system to unify existing tags for all kinds of educational institutions. The new system would introduce some new tags but also change many existing tags.
  • User erkinalp wants to propose a new tag for magnetic levitation trains. The tracks they use are incompatible with conventional rails.


  • Adrien Pavie has created Whatosm, a tool that, depending on the difficulty level, desired time, and whether you want to map outdoors or at home shows different possibilities of how to contribute to OpenStreetMap. The source code can be found here, and you can help with the translation of the tool into different languages here.
  • The OSM blog published the results of the projects related to OpenStreetMap of this year’s Google Summer of Code.


  • User GeoKitten asks for help on the mailing list “imports” for importing building data in Allegheny County, Pennsylvania. This member is at the first stage of an import, while it’s good to disseminate that an import is in the works, it would be important to follow up as the import progresses. This might bring in more people to help this member and also be instructive about the many details of doing something this complicated.
  • Vincent Frison has the intention to import building heights in Nice. More detailed information on the project can be found in the wiki page.
  • Vivek Bansal asks for reviews of the San Jose, California sidewalk (pavement) import.
  • To bring in line the 40,000 wikidata tags that do not fit the Wikipedia URLs Yuri Astrakhan suggests to resolve the problem with a script. On the mailing list, Osmose and MapRoulette are mentioned as alternatives which would involve the community.Yuri Astrakhan’s second post leads yet again to a longer discussion about missing wikidata tags and if they should be added automatically. In the mean time Yuri started a mechanical edit and received a bunch of complaints due to the bad quality of his edits.

OpenStreetMap Foundation

  • The data working group asks mappers to participate in an opinion survey, concerning a policy for organized and paid mapping. On the talk mailing list there is a discussion. Christoph Hormann explained in his blog, why such a policy is needed.
  • Michael Spreng asks for feedback from the OSM Foundation members on the Membership Working Group’s proposal of the Membership Fee Waiver Program.
  • Dorothea from OSMF writes about joining the OpenStreetMap Foundation to help shape the future of OpenStreetMap. She emphasizes on this being an opportunity to be a voice in the governance of the Foundation – the organization which owns and maintains the servers, holds the license, runs the State of the Map, coordinates local chapters.
