About us

  • Five years of weeklyOSM in Portuguese! That’s right, it was five years ago that we started this adventure of translating (and then revising) weeklyOSM articles into Portuguese. We started with weeklyOSM 431 and now with this issue we have achieved 262 issues uninterrupted! We hope you enjoy our work! weeklyOSM would be much richer if everyone in the Portuguese-speaking community shared articles.Did you know that you can also contribute? Find out here.The editors of the weeklyOSM for the Portuguese language: Elizabete Oliveira and Nuno Azevedo send their warmest greetings from the Azores.

  • Vincent de Château-Thierry has announced , on Mastodon, that the file replacing FANTOIR has finally been made available by the French Public Finance Department. This will make it possible to update the content of BANO and improve street mapping via Pifomètre in France. Pifomètre enables OSM data and FANTOIR to be reconciled by displaying a list of matched and not yet matched roads, by municipality.
  • Ilya Zverev explained some of the OpenStreetMap tags needed for mapping trails.
  • A request has been made for comments on crossing:continuous, a tag for mapping if a footway, cycleway, or similar continues uninterrupted across a road.

OSM in action

  • According to the accident statistics of the Social Insurance for Agriculture, Forestry and Horticultural Affairs (SVLFG), forestry work is one of the most dangerous professions in Germany. To make it easier for rescue workers to locate people in need of help, Intend GmbH has published the data set of the KWF (Board of Trustees for Forest Work and Forest Technology) in the app ‘Hilfe im Wald’ (help in the forest). It uses OpenStreetMap in the background and has the existing rescue points .
    In 2014 the community in Germany had executed a weekly task (for ‘CraftMapper’). Although the KWF data is under an ‘open licence’, according to information from KWF it cannot be transferred to OSM because of the licence.

Did you know …

  • … that you can help improve the shoreline and administrative boundary data in OpenStreetMap by using the OSM NightWatch app? The source code for this app is available on GitHub.
  • … that the opening_hours tag has very complicated rules? However, you can use the Web to OSM Opening Hours app to automatically generate the tag from a URL or free text.
  • … that MapComplete now comes with layer artwork? The data is retrieved in real-time using Overpass or OSM API queries, and you can also add new data to OSM directly through MapComplete.

Other “geo” things

  • Some geographical coordinates on Earth have been dubbed “poles of inaccessibility” because they are the most remote point inside a boundary. One of them is Point Nemo, the point in the South Pacific Ocean region that is the farthest away from the shore.
  • Nicolas Lambert explained why we shouldn’t add scale bars to world maps.
