- weeklyOSM contributor Rogehm has published his interview with Lamine Ndiaye, who uploaded changeset 10⁸.
- TheSvawu has tweaked “osm-in-realtime” so that it starts at 99,999,800, so that you can look again at the mapping activities near changeset 100,000,000. Interesting to see who was mapping around the magic number. It is also interesting to read the comments on some of the changesets 😉
Changeset Mapper Comments ..99,999,991 LucGommans “Greetings from the Netherlands!” ..99,999,999 AE35 “99999999 is definitely a cooler number than 100000000” 100,000,000 Lamine Ndiaye mapper of changeset 10⁸ 100,000,001 MikeN “Congrats on the 100,000,000th changeset!!!

- We just had the 100 millionth changeset and at the same time the 8,458,919,620th node and the 910,977,970th way. Here you can see when 110 million changesets, 10 billion nodes and 1 billion ways are to be expected.
- As directed by OSM’s Organised Editing Guidelines, the Tallinn-based company Bolt is now writing to communities in a number of OSM countries about where they are planning to map. Reactions have included ‘our roads are already complete’ and ‘contributions in newly-built suburban areas might be helpful’. Bolt were originally brought to the attention of OSM’s Data Working Group, not because of poor mapping, but because a local OSM community (in Sweden) didn’t know who they were, because the initial changesets and user account details did not say – a clear indication of the advantage to the company doing the mapping of following the guidelines.
- Last week we reported on the longest highway on OSM. No sooner had we done so than Christoph Hormann (imagico) added a correction to the thread ‘you are not even close’.
- Kevin Karson (user karsonkevin2) has been extending the mapping of athletics tracks in Iowa, and produced a visualisation showing every track in its correct orientation. Click on a track to see it on OSM.
- Stephanie May has been mapping parklets in Seattle, as they are particularly valuable during these Corona times. They opted for
outdoor_seating=parkletas the main tag, but in the San Francisco Bay area
leisure=parklet(not documented) has been used, so they are seeking further views on the matter. (A similar discussion occurred recently on the UK mailing list, which threw another option into the mix:
- The following proposals are awaiting comments:
historic=tomb, proposed by Martin Koppenhoefer, to provide a tag for all kind of tombs: mausoleums, pyramids, simple tombs, prehistoric tombs, tumuli, rock-cut tombs.
nudism=designated, proposed by Tamas Rell, for a beach/resort/etc. which is officially designated as nudist, but nudity is not obligatory. Basically an official public nude beach.
- Voting has ended for the following proposals:
historic=ogham_stonewas successful with 14 votes for, 1 votes against, and 1 abstention.
- Luc Gommans provides a formidably detailed analysis of how mappers tried to game being the person to make the milestone changeset of 100,000,000 (which we featured last week). Clearly, this event brought out the inner geek in many of us.
- Using data from the recent OSMF Community Survey, Jennings Anderson posted an analysis of per-country editing activity since 2020. The distribution of local/non-local mappers per country and the number of edits per user vary greatly among countries. The analysis notebook is available online.
- Have a look at the International Women’s Day 2021 events! The American Red Cross and Missing Maps are hosting the International Women’s Day Mapathon 2021.
- Mike Collinson gave an excellent summary of ‘how we got to where we are’ with
surface=*, on the Australian mailing list.
- On 10 and 11 March (Wednesday and Thursday) OSMF Chair Allan Mustard will present a series of three BigBlueButton video conferences open to the OSM community to answer questions about the survey results. The sessions will be at noon UTC and 20:00 UTC on 10 March, and 04:00 UTC on 11 March (these correspond to 07:00, 15:00, and 23:00 EST). He will present some summaries of the data in graphical form, then take questions. He will use his BigBlueButton home room.Allan also plans to open an instance of Microsoft Translator and will share the access code for the instance at the start of the presentation, so that anybody with Microsoft Translator’s app (on desktop, notebook, tablet, or smart phone) can follow the presentation in the language of their choosing. He will also use the PowerPoint 365 speech to text feature to offer English subtitles. Anyone planning to view the video conference should download the Microsoft Translator app in advance and become familiar with it first.
- Christoph Hormann shared > his insight about a Meeting of the OSMF Board with the Advisory Board, Local Chapter Members and an ESRI representative, held on 24 February.
- Michal Migurski prepared two diary entries with maps that illustrate the results of the OSMF Community Survey. The first post focuses on mappers and survey respondents, while the second is dedicated to Board priorities and technology policies.
- Giuseppe Puntofisso, the head of NHSX (AI skunkworks for the NHS) is experiencing difficulty contacting the OSMF Legal working group.

- Hell freezes over: UK’s Ordnance Survey has launched an OSM-based app in Australia.
- Last summer Ivan Gayton explained eloquently how the use of proprietary software reinforces racial and postcolonial inequalities. High costs, and erroneous cost-benefit analyses associated with proprietary tools, mean that it is mainly people from Western countries who acquire expertise. People from affected areas therefore benefit much more from the use of free software. Imma Mwanja recommended the article in the course of the webinar ‘Colonialism in Open Data and Mapping’.
- The Swiss OpenStreetMap association (SOSM) welcomed swisstopo, the national mapping agency, to the open data world. The blog post explains some caveats about the licensing of swisstopo data in the context of OSM.
- Nuno Miguel Azevedo reported in a tweet that the Angra do Heroísmo City Council, in the Azores, recently launched the app MyAngra, available for Android and iOS. It is a tool for locating the main points of interest in the municipality. What’s missing is the proper licensing and attribution of the base map to OpenStreetMap.
- Nominatim, the open-source geocoding tool based on OpenStreetMap data, introduced a command-line version leading to many changes such as much less fiddling with PHP scripts.
- The free software Offroad is an offline map viewer for the desktop. It is based on OsmAnd.
- In episode 61 of the Geomob Podcast, Ed Freyfogle talks with Sam Crawford, developer of Trail Router, an OSM-based route planner for runners.
- You can read a dialogue-like tutorial between Pierre Béland and Jean-Marc Viglino, the author of the ol-ext OpenLayers Extension tools, about the dynamic addition of layers to an OpenLayers Map using WMS Servers catalogue queries.You can test yourself with the WMS Capabilities example providing your own GetCapabilities request like this for OSM-France https://wms.openstreetmap.fr/wms?service=wms&version=1.3.0&request=GetCapabilities (For security reasons, OpenLayers accepts cross-origin requests only if authorised by the WMS Server with the header [Access-Control-Allow-Origin, *].)
- Version 3.0 of Nominatim-UI adds theming and other features which make the user interface independent from the standard installation on openstreetmap.org servers.
Did you know …
- … the OSM principle that you can use any meaningful tag you want? Sometimes it’s helpful to coordinate with other community members, but that’s not a requirement. Think of a meaningful tag, make sure it doesn’t clash with or contradict tags already in use, document it on the wiki, move out into the world and map!
- … that the UN Mappers run weekly mapathons? Two hours with them to learn, discuss, and map together, supporting UN peacekeeping missions in Africa. Each week an in-depth look at a different topic! You can register here.
