Humanitarian OSM

  • With support from the Humanitarian-to-Humanitarian Network (H2H Network), HOT is engaging the humanitarian mapping community worldwide, thereby strengthening global and local COVID-19 approaches.

As a background you can choose between the OSM map, a Google map, or a satellite image. The menus (so far: DE, ES, EN, PT, RU) are now also available in French.
  • Walter Nordmann (wambacher) released version 1.2.4 of his Healthcare Map with German, French, and English menu navigation, better icons and other improvements. Currently permalinks will not save the active layers.

Open Data

  • InsideIT.ch reported (de) > en about a new digital service from the Federal Office of Topography (swisstopo), freely accessible for companies, research and science, e.g. engineers, architects, programmers or planners but also private users. The data may also be used for commercial purposes free of charge. The only condition for publication is that the source is acknowledged.Included in the geodata offered are most digital products such as national maps, aerial photographs, landscape models and geological vector data. Every current dataset is now available in the most common formats and variants. No registration is required to download and use the services. In this way, Switzerland intends to make an active contribution to innovation and economic growth.
  • Paul Keller and Alek Tarkowski are founders of ‘Open Future‘, a ‘think tank for the Open Movement’. Classic projects such as Wikipedia/Wikimedia and OpenStreetMap are part of it. They were interviewed (de) > en by netzpolitik.org.

Did you know …

OSM in the media

  • Tech Exec reflected on the performance, strengths and weaknesses of OSM, most of which would have been familiar to readers of the corresponding OSM wiki page.
  • Tages Anzeiger took (de) (paywall) an in-depth look at the implications of swisstopo open data (as we reported earlier). Although OSM is one of several likely uses mentioned, a couple of the experts quoted may be familiar names: Stefan Keller and Simon Poole.

Other “geo” things

  • Carolin Klonner, and others from GIScience Heidelberg, have published a paper about the OSM Sketch Map Tool. This supports participatory mapping approaches and risk communication using and extending OSM Field Papers. It also includes a fitness-for-purpose analysis of the OpenStreetMap data for the respective region, similar to the approach in the ohsome Quality analysT (OQT) tool.
  • Engaging Data provides an unusual interactive map that combines a planet (or moon) of the Solar System and a country/continent of choice.
  • Check out this impressive animation of the year-to-year increase in node density of OSM data in the Philippines from January 2012 to January 2021.
