Mapping

  • ENT8R has developed a website called Notes Review. It enables you to perform a full text search of OSM Notes and view them quickly.
  • Following up his earlier message about mapping underrepresented features (reported earlier) Rory McCann has launched a survey via the Diversity mailing list to select suitable topics for quarterly challenges.
  • Robert C. Danziger (user RCD49) asks mappers not to use satellite imagery to map Larabanga, Ghana, as they are outdated. He has also prepared a wiki page with the current mapping workflow and tips on how/what to map remotely.
  • Pascal Neis updated his “Find Suspicious OpenStreetMap Changesets” with new indicators.
  • Vote on the public transport hail and ride proposal until April 24th.

Community

  • Pascal Neis mentions on Twitter that changeset 51820940 is the one that had the most comments (113). The issue is that Belarusian is the official language on the ground in Minsk, Belarus, but the local population speaks Russian there, so all the names were added in Russian in the name tags.
  • Dominique (@dominique_hoavo) presents on Twitter a review of the Girls Map for Togo initiative (#GirlsMap4Tg) that occurred April 11th to 13th.
  • User Escada interviewed Andrew Harvey from Australia for his Mapper of the Month series.
  • Jakub Klaučo explains how he created a high-resolution world map poster, using Python and TileMill. He is currently accepting suggestions on how to wrap around the 180th meridian.
  • Daniel Begin, Rodolphe Devillers and Stéphane Roche published a paper called The life cycle of contributors in collaborative online communities – the case of OpenStreetMap in the International Journal of Geographical Information Science. The paper published in 2018 is based on a four-year old full history planet dump.

Imports

  • Cascafico Giovanni wants to import petrol stations in Italy from an official source.

OpenStreetMap Foundation

  • The Data Working Group has published its Activity Report for the last quarter of 2017.
  • OSM US has engaged Allen Gunn to help them find an executive director.

Events

  • The Call for Proposals and Call for Scholarships for State of the Map Asia, happening in Bengaluru this year on the 17th-18th of November, is out. You can submit your proposals by the 10th of June 2018 midnight UTC.
  • The call for venue for the State of the Map 2019 is open until May 6th. So far only Tunis has applied.

Humanitarian OSM

  • Fred Moine informs (fr) that he conducted a training in Goma (Democratic Republic of Congo) at the initiative of OSM-Kinshasa to develop a local community there. He thanks “Les Géographes libres” for the training material.
  • Blake Girardot rounds up a few tweets @hotosm over the last weekend.

Open Data

  • The beta version of the Wheelmap now includes information about the operating status of elevators and escalators of Deutsche Bahn. (via Twitter)

Programming

  • In the previous issue we reported on Arne Johannessen’s thesis on the generalisation of roads. A small discussion about generalization in general has started on the osm-dev mailing list as a result.
  • Leaflet developers are considering to drop support for versions 8 to 10 of Internet Explorer.
  • Andy Allan posts about his work on refactoring the code of osm.org, so that it will be easier to add new features: This should help to attract new developers.
  • The Heidelberg Institute for Geoinformation Technology (HeiGIT) released a new open source microservice for searching OSM points of interest (POI) through specifying feature-buffers, polygons or bounding box. It returns GeoJSON features or simple statistics of categories. Are there any Python developers interested in contributing?

Releases

  • Komoot’s open geocoder Photon reaches version 0.3.0, which includes major updates of software dependencies and a number of improvements on reverse geocoding, house number handling and location bias computing.

Other “geo” things

  • Jessica Sena posts the process behind the Streets of Women (#LasCallesDeLasMujeres), a project by GeoChicas using Mapbox and NamSor APIs.
  • Páraic and Pearse McGloughlin created “Arena”, a mesmerising film made with satellite imagery from Google Earth.
  • Despite Australia’s rather accurate mapping on OSM, some people insist on believing it doesn’t actually exist. This theory is only the last of many conspiracies or jokes that deny the existence of countries and cities around the world, listed in this article from The Guardian.
  • Mapillary announces a new, 15 million USD round of investment with BMW i Ventures, Samsung Catalyst Fund, and NavInfo joining in as investors.

About us

  • Last week we reported about the revert of invented names for runways. Contrary to our report, the revert itself and the noname=yes was not performed (de) by Frederik Ramm.

Mapping

  • John Willis looks for the most appropriate tagging for flower fields specifically cultivated as a tourist attraction.
  • Thorsten Engler in Australia criticized the mappers from Microsoft’s open data team, because they added, in his opinion, unnecessary turn restrictions near roundabouts.
  • Mateusz Konieczny suggests changing the description of amenity=bus_station in the OSM wiki.
  • On talk-de a discussion is going on about whether to glue landuse to highways (reuse their nodes), or not. The project started out as an abstraction, so reusing the nodes of highways to avoid empty triangles in the rendering was the best solution for a long time, at least until we started to be able to map in more and more detail thanks to better imagery. Now it is perceived as imprecise by some and annoying by others. It seems like we will have to map all the highways as their own landuse areas (comparable to larger rivers), in order to avoid empty spikes on the map.
  • Over the past weeks, a probably organized, group of mappers corrected alleged mistakes on roads (gaps, one-way streets, bans,…) in Germany and Great Britain, but did so in an incorrect, possibly automated way, thereby hiding real mistakes. See the discussion in the German forum and two emails on the talk-gb mailing list.
  • Nicolas Chavent published a Twitter moment about the open science based project CohéSIoN in Bouaké (second city of Ivory Coast) where after two weeks of training, a mapping collective (local OSM members and young researchers) have started a four week long urban survey based on OSM: buildings, health, education, Central State and local authorities amenities, places of worship, markets and drinking water points.
  • DWG has blocked 29 user accounts editing in Jakarta on behalf of GlobalLogic India because a local mapper felt overwhelmed.
  • User pierzen created a new MapCSS style for JOSM to visualise boundary relations with user configurable levels.
  • Another group of organised mappers adding minor roads attracts attention in India due to editing errors and unsuccessful attempts to get in touch with them. DWG issued user blocks on their accounts.
  • After several years of mapping public transport and looking in different places around the world how it is done, user Polyglot proposes a simplification to the schema to make it straightforward to understand and maintain for all mappers.The principle hinges on using nodes next to the highways/railways to represent the stops for their full ‘lifetime’ and only adding these nodes to the route relations, one object per stop. This does not mean that platform ways/areas can’t be mapped any more in addition to these nodes.

Community

  • On the osm-talk mailing list, Daniel Koć announces the creation of a new subforum focused on OSM Carto rendering.
  • User Michał reports about a bot that comments changesets with wrongly tagged addresses and wonders about the community’s opinion on this practice.
  • User rurseekatze proposes (de) (automatic translation) to delete wiki pages of municipalities and counties lacking maintenance and proper content.

Imports

  • The OpenStreetMap communities in France and Germany reject the NavAds gas station import due to quality issues.

OpenStreetMap Foundation

  • The Minutes of the Engineering Working Group meeting of April 5th was published.

Events

  • From October 5th to 7th, Detroit is the place to be for the State of the Map US.
  • On April 23rd there will be a Field Cartography Workshop in Grenoble, France. It will be a mapping party with specific focus on mobile apps, but also a small retrospective step with Walking Papers.
  • The organizers look back (de) at FOSSGIS 2018, the German conference for OpenStreetMap and open source software. With 465 participants, it was the second-largest FOSSGIS so far.
  • State of the Map Asia 2018 is happening in Bengaluru, India from 17th till 18th of November. You can already submit proposals for talks or workshops.

Maps

switch2OSM

  • Met Éireann, the Irish Meteorological service, uses OSM as its background map.

Software

Programming

  • From May 7 onwards all unencrypted HTTP requests will be forwarded to planet.openstreetmap.org on HTTPS (port 443). For Curl, Java (Osmosis) and other HTTP clients this following of redirects must be activated manually!
  • Arne Johannessen has published his diploma thesis (PDF) with the title “Algorithms for automated generalization by combining polylines in OpenStreetMap for specific special cases” and he also released the corresponding Java source code.
  • Jochen Topf presents the innovation of Libosmium 2.14 and Osmium-Tool 1.8. Many bugs related to missing timestamps and other metadata fields have been fixed and the ability to write OSM files with only certain metadata fields was added.

Did you know …

Other “geo” things

  • Jason Grinblat (@ptychomancer) tweets about his love of map generators, and demos several of them, for example, Red Blob Games’ Map Gen 2.
  • Damon Burgett from Mapbox explains how his team developed a Satellite Health Index. Taking the distributions of users into account, this tool finds the priority areas for imagery updates.
  • Cityzenith launched the commercial Smart World Pro 3D data platform, which allows to combine many different data sources in 3D visualisations, including OSM data.
  • On the 50th anniversary of Martin Luther King Jr.’s assassination, National Geographic created a magazine with pictures of streets around the globe dedicated to his memory. Further pictures are reachable via Google Street View and an interactive OSM map.
