Lügen mit Zahlen

Frederik Ramm demands honesty in dealing with figures from OSM. Among 83,025 doctors, only 1033 are gynaecologists. True, but only 18,728 doctors have a specialty and gynaecologists are the most common (5.52%) after general practitioners. 1 | © Picture by Frederik Ramm


  • Stéphane Péneau wishes (fr) to crowdfund the conception and production of a GNSS receiver that would be particularly suited for OSM contributions. The ongoing discussion should help to refine the specifications.
  • In his diary, Martijn van Exel details the beta of Maproulette 3.0.
  • Ilya Zverev (Zverik) posts his analysis of the impact of the new iD release: OSM-based routing engines need to correctly process the increasing number of intersections with “via” nodes and no-U-turn restrictions.


  • Mappers from OSM Benin community, in partnership with the French Research Institute for Development and Blolab, drove during the last two weeks the MapAndJerry mapping phase, alternating training and field collection. RFI made a video report (fr) of the event.
  • In #400 we reported about “Who Maps the World?”, published on CityLab. In his presentation at FOSSGIS 2018, Frederik Ramm tries to analyse (de) the gender-relevant facts neutrally and with the knowledge how OSM works and comes to surprising results.
  • A thread on the Austrian subforum deals with the possible need of a moderator. In the end, emga and Nakaner were appointed as new moderators.
  • User ImreSamu has created test instances of Taginfo and made them available online for testing and feedback.
  • To improve the rendering of 3D models in OSM, user n42k created a repository in the last Google Summer of Code (https://3dmr.eu/) where the models are stored. He also wrote a diary entry.

OpenStreetMap Foundation

  • The minutes of the Membership Working Group meeting of March 20th is online. The main point on the agenda was the setup of an OSMF-owned survey engine.


Humanitarian OSM

  • Amelia Hunt reports on the HOT blog about improving access to health facilities in Dar es Salaam. Surveys were conducted among the population. A visualization shows problems and possible solutions. Especially in the field of obstetrics, mobile clinics could make life much easier for the female population in Tanzania.
  • During the National Mapathon (translation) in Belgium, around 200 mappers added 1000 km (translation) of roads and 70,000 buildings to the map in Nigeria.

  • The German national news service Tagesschau has created a news atlas on OpenStreetMap basis, which shows 24-hour news.


  • The osm-carto team has published a new monthly release of this style (v4.9.0), with 2 times more changes than usual. Some of them are pretty important, like long-awaited towers and masts redesign, new rendering for gardens or rendering place=square labels.

Did you know …

  • … the Cycling Infrastructure Prioritisation Toolkit, in short CyIPT? It’s a toolkit that identifies the best places to put new cycle infrastructure.

OSM in the media

  • The OpenStreetMap community in Chile has tweeted that OSM data can now be seen daily in the official news and on their Facebook page.

Other “geo” things

  • After ‘fake news’ now fake destinations on road signs.
  • The tree management software ImmoSpector tree lists (de) OpenStreetMap among the possible map background layers. This software aims at monitoring tree cadasters with online tools.

  • The launch of a SpaceX Falcon 9 rocket produced circular shock waves in the ionosphere that could lead to GPS errors of about 1 metre.

One Reply to “(English) weeklyOSM 401”

  1. I appreciate English might not be the editor’s first language, but the word “neutrally” in English generally means trying to present something in an unbiased or non prejudicial way, considering both sides and not being judgmental with regards to a topic.

    The title of Herr Ramm’s talk seems to be “Lying with Statistics” (I am not a native German speaker).

    That is the opposite of “neutral”, instead, that is extremely judgmental, accusatory and biased.

    In addition, calling the folks who engage in gender analysis based on OSM data “outsiders” is equally biased, dismissive and insulting.

    If you wish to be honest, you will remove the word “neutrally” to describe his talk, since at least based on the title and talk description, it seems to be very from neutral.

    There were lots of ways to approach the topic of analyzing OSM data and meta-data to try and understand some social questions, but calling analysis you disagree with or fail to understand “lying” is about the worst approach of which I can think.

    Perhaps I misunderstand something given this talk is not in a language I speak, so I am certainly open to an explanation about how titling a talk “Lying with Statistics” is really a neutral title.
