Typical errors that can be solved with Jochen Topf’s MapRoulette task 1 | (C) OpenStreetMap Contributors CC-BY-SA 2.0

Mapping

  • [1] Jochen Topf has started a Maproulette-Challenge to repair invalid areas in OSM and wrote in his blog about it. Let’s begin with self-overlapping closed ways with tag building=*. More Challenges
  • As part of the “fixing broken multipolygons” discussion, Christoph Hormann suggests that removing forest polygons from the old Corine landcover imports might be a better solution than repairing them, because they are very inaccurate.
  • CloCkWeRX posts on enhancements proposed to OnOsm.org, some of them have already been accepted, for example, the location helper and internationalization, among others.
  • Bryan Housel shows how picnic sites can be mapped easily using the iD editor and multi-selections.
  • User Jojo4u proposes a new feature “meadow orchard” (German: “Streuobstwiese”) which is a meadow with scattered fruit trees or fruit trees that are planted in a field. The proposed tagging is possible with combinations of landuse=meadow or landuse=orchard.
  • On talk-fr, Rogelio brings up the matter of toll fee data into OSM. It’s not clear if having this information in OSM is desirable or even feasible but some options are discussed to ease the integration of toll fee prices for OSM-based routing engines.
  • Martin Koppenhoefer proposes the documentation of the usage of amenity=luggage_locker and amenity=locker tags. This initiates a discussion on the need for two different tags for a seemingly similar utility.
  • The usage of amenity=vending_machine tag was discussed at length on the Tagging mailing list including what is within the scope of the term ‘vending’ and what are the alternatives to the amenities tag.
  • Joost Schouppe writes about evaluating completion of the road map network in Flanders, Belgium. A thorough analysis is made along with many graphs and time-lapse animations.
  • User Marczoutendijk wrote an article about the tagging of restaurants and its particularities in OSM. Bon appetit!
  • The Mapbox Data Team invites you to map points of interest in San Francisco using JOSM with the Mapillary plugin. A comprehensive guide is provided and the project is open on the Mapbox tasking manager.

Community

  • JOSM maintainer Dirk Stöcker is concerned about the increasing gap between the translations. He is told that the launchpad translation platform is the problem.
  • Steve Coast showcases his OSM Stats website where the evolution of the various types of ways can be gathered by country. Direct links to: UK and US.

Imports

  • Facebook are suggesting that they try again with their “AI-based” road detection. Last time it didn’t work so well. Last time, imports in Egypt and Thailand were reverted because they were “far more wrong than right” (draining ditches being added as “roads”, among other things). Apparently this time they are now working with a larger team of highly-trained mappers and have added steps to the validation process.
  • Nick Bolten, of the projects OpenSidewalks and AccessMap, announced a test import of footpaths in Seattle (Washington state). There were already extensive discussions on the mailing lists tagging and Imports.
  • Max Bainrot suggests to use the ACTmapi data from Australia for OpenStreetMap. The data is under CC-BY, but there is probably a special permission for OpenStreetMap.

Events

  • The submission of talk proposals for the 2017 State of the Map in Aizu-Wakamatsu, Japan is open until April 2nd.

Humanitarian OSM

  • Mikel Maron reports that Mapbox has matched a US$ 10,000 grant to the HOT Microgrants Program (which we reported earlier).
  • User MangleBlanco writes about impressive geological history of the Southernmost tip of the Caribbean Sea and why open source data might be key to sustainable development in the region. He also pledges to provide high resolution data for mapping efforts and humanitarian projects in the area.
  • It seems that Fred Moine is not quite convinced by the quality of the mapping in Haiti by HOT volunteers.

Maps

  • The OSM website now has a new right-click context menu which was programmed by user mcld. You can now set directions to and from points, centre the map, add notes, etc. The item “show tile image”, which was available in the previous browser-default image context menu, is missing. Ilya Zverev proposed to add it, but his pull request was denied – a long list of comments criticizing Tom followed.
  • Mapzen added a new feature to the Who’s On First Spelunker: the Bundler. Now, after you selected a place, downloading a GeoJSON blob containing all its descendants with selectable categories is a few clicks away!

Open Data

  • Do you already know the Open Digital Elevation Model – “The Portal for sharing the 3rd dimension”? At the beginning of the year, North Rhine-Westphalia (DE), Belgium, New Zealand and Switzerland joined.
  • Open data under Trump probably doesn’t exist any more. The White House’s Open Data Portal has been emptied, user @denormalize reported on Twitter.

Licences

  • KSJ2 data in Japan must not be imported any more because the terms of use have been changed (source).

Software

  • An introduction tutorial for QGIS Atlas, a QGIS feature (formerly a plug-in) that allows you to create map snippets around a collection of features (eg a POI shape file).
  • Ilya Zverev announced a new import tool. The OSM Conflator checks for matching objects in the OSM data. It adds tags to existing objects or creates new nodes for unmatched points.
  • Martin Ždila announced his Toposcope Maker. Toposcopes can be found on top of hills or high places which indicates the direction to notable landscape features or cities.

Programming

  • Frederik Ramm (woodpeck) submitted a pull request which would allow the geometry of deleted OSM objects to be displayed on “browse” pages. It was rejected for various technical reasons – see this comment by Matt and the comments above for a summary.
  • Geofabrik announces that the download server now has full history files for all regions served. These files (called “.osh.pbf”) can be used to run analyses, and one can use Osmium to convert them to a text-based format (“OPL”) that is then accessible for grep et al.

Did you know …

  • …the historic maps of Berlin? Here you can see them as an adjustable transparent layer on top of OSM.

OSM in the media

Mennonites in Bolivia start mapping with local knowledge 1 |

Mapping

  • The German forum points out (automatic translation) that glass recycling containers for bottles and jars should be tagged as recycling:glass_bottles=yes only, since the simpler key recycling:glass=* includes types of glass which are not accepted.
  • [1] The Mennonite community of Colonia Pinondi in the Bolivian lowlands has started mapping its municipality in OSM with local knowledge. (Via OSM Cochabamba). We think it is a good example for Mennonite communities all over the world. 😉
  • Martijn reports about his visit to an OSMTime event in Cluj, Romania. Beata Jancso from Telenav organises OSMTime, a mapping event, once a month.
  • Arun from the Mapbox data team exhibits the mapping of a street as an area. Specialized maps could get even better rendering results.
  • Jherome Miguel asks for comments on his suggestion of the extended tagging of power poles.
  • Joost Schouppe asks on the Tagging mailing list about how to tag knotted willows and search for English terms.
  • Editing a single node with Level0, built a transcontinental highway from Europe to Brazil.
  • Pascal Neis’ Suspicious Changesets now also displays rough-cut views of the content of suspicious changes. It does that using the Augmented Diffs of the Overpass API (Source: Twitter)

Community

  • Christian Bittner wrote an article on OSM in Israel and Palestine. He notes, among other things, that the OSM data and the maps derived from it are of particular importance in this political conflict (keyword: “ground truth”). Since it’s not an open access-publication, Christian shares PDFs upon request by email.
  • Ediyes shares her experience in mapping her hometown of Andahuaylas where she improved existing streets, added names, points of interest, parks, etc.
  • Peter Barth summarizes the results of the last Google Summer of Code and invites students to take part this year. If you are interested, visit the ideas page in the OSM wiki.
  • Martin Dittus (dekstop) presents the results of his research on how feedback on tasking manager affects the further activity of newcomers. Unfortunately, he does not disclose the rules by which he has classified the individual personal messages.

OpenStreetMap Foundation

  • On the 12th February several OSMF operated services got new SSL certificates by Let’s Encrypt. Now you also get a valid certificate if you request foobar.osm.org instead of foobar.openstreetmap.org. (source: Chef repository of OWG)

Humanitarian OSM

  • The Irish MapLesotho group is again visiting Lesotho and there is a report about their work on Twitter too.
  • HOT reports about their new mapping projects that have started in Istanbul and Uganda and is increasingly focusing on crowdsourcing to make high-quality maps available for these regions.
  • LearnOSM has been updated with some interesting sections which include a guide for anyone to organise a Mapathon, tips aimed at new mappers which include an introduction to iD and tasking manager, and much more.
  • MakingMalariaHistory reports on a joint project to fight Malaria. Everyone with an OpenStreetMap account is asked to help.

Maps

  • The LA Times published their code to generate web based maps using Mapzen’s Tangram.

Open Data

  • The Landsat program has a Twitter bot uploading images. Learn more about it.
  • OpenDataSoft published a post discussing the nature and representation of public transport data from heterogeneous sources. French open data providers are listed, and both static and dynamic feeds are aggregated on a single map.

Programming

  • Ilya Zverev from MAPS.ME submitted a pull request which adds MAPS.ME as an authentication provider for the OpenStreetMap website, i.e. users can log in with their MAPS.ME account.
  • Peter Liu from Mapbox, explains how he used satellite imagery and height data to generate an interactive 3D map using Three.js. He plans to make a similar demo with Unity next.
  • The behavior of osm2pgsql when no database is specified using the -d option will change in the next release. Up to now, the default name is gis.
