Mapping

  • mapmeld made an interesting analysis of language clusters by using Unicode code points. They also detected outliers and odd forms of vandalism.
  • The vote on the proposal “Fashion accessory shop” has begun and runs until 8th April 2019.
  • The vote on “Substations functions” ended. The proposal did not achieve the necessary majority.

Community

  • alexkemp describes how he resolves problems encountered with OSMTracker 0.7 when pictures aren’t georeferenced. He shows how he restores the missing data.
  • SK53 wanted to identify areas of social housing in England. He shows in his blog how he was able to create suitable useful polygons from an open data list of individual properties with PostGIS clustering. He suggests that such approaches may have broader applicability to OSM data.
  • Ilya Zverev recently started working for the taxi company Juno. He describes how GPX tracks from the Juno app are being aggregated and how they can be used to keep OpenStreetMap up-to-date with very fresh data. This data is a lot easier to work with than the GPX tracks stored by OSM, which may cover multiple changes in the road network. He also presented on this subject at FOSDEM in Brussels, and his talk was recorded.

Events

  • FOSS4G Argentina, a conference with workshops and presentations, takes place from 9th – 12th of April 2019 in Buenos Aires. Registration is open and it includes a workshop on how to use JOSM for editing by (@Hernan)
  • The Linuxwochen 2019 tour through Austria will be in Vienna from May 2 – 4. The article contains some links to video recordings of earlier Linux weeks. (de) (automatic translation)
  • Entur and Ruter are hosting an OpenTripPlanner Summit in Oslo on 3rd April. The proceedings will be live-streamed.

Humanitarian OSM

  • HOT has created a new development community for the Tasking Manager with further partnerships with Microsoft and Bing Maps. Over the next few months, work will begin on the design for integrating machine-learning and improving workflow performance of the Tasking Manager. Additionally open building datasets for Uganda and Tanzania will be created.
  • In order to be able to help people in crisis areas quickly, NGO helpers depend on high-quality maps. For many areas, these maps must first be produced. In doing so, Doctors Without Borders is supported by modern technology and by thousands of volunteers. On Tuesday 2nd of April 2019 from 19:00 – 22:00 interested people will meet for a Missing Maps Mapathon in Berlin.

Maps

  • PrivateMajory tweets a 3-D effect map made using QGIS and then enhanced in Blender.
  • DJI appears to be using (in certain countries) OSM data in their Fly Safe GEO ZONE Map
    (several examples). A tweet and emails have been sent to DJI requesting correct attribution, but sadly there was no reply from DJI.
  • The OpenStreetMap.be website now has a brand-new “How To” page with some tutorials and example code to demonstrate on how to use OSM and OSMBE base layer.
  • The first version of the Baby Map was published. It represents the tags that are relevant for parents of small children. However, the data in OSM is still a bit thin.

Programming

  • The German forum discusses (automatic translation) the categorisation of notes on osm.org. The forest of “Notes” markers is often dense and a categorisation by urgency or keywords could have a positive effect on the processing of the messages. User miche101 arranges notes on a map assigning different symbols to the markers based on keywords.
  • The GISience News Blog of the University of Heidelberg previews a new way to query spatial links in the OpenStreetMap history database OSHDB.

Did you know …

  • … the 2 Minute introduction videos to help beginners get started with OpenStreetMap and mapping for HOT-projects? Vitor George reminds us of the possibility to add subtitles to these YouTube videos.
  • … how to tag an area that is covered by trees, but neither tagged as landuse=forest nor natural=wood such as for example a cemetery? These can be tagged using landcover = trees along with their default landuse tags.
  • … the smartphone app ViewRanger ?

OSM in the media

  • The Free Software Foundation (FSF) recognised OpenStreetMap with the 2018 Free Software Award for Projects of Social Benefit and Deborah Nicholson with the Award for the Advancement of Free Software. Kate Chapman received the award from Richard M. Stallman at the Massachusetts Institute of Technology (MIT) and gave a speech on behalf of OSM/OSMF community.
  • The Open Mapping Group at McGill University in Montreal, Canada, hosted an indoor mapping party in the face of frosty weather.

Other “geo” things

  • The International Telecommunication Union (ITU) published a report on reliefweb.int about the use of disruptive technologies in disaster management. The digital technologies that are supported by many volunteers around the world in the crowdsourcing projects such as OSM are highlighted in particular.
  • Nazi spies, untroubled by the Soviet authorities, made a complete map of Moscow during the late 1930s.
  • Yahoo Japan news reported that Google Maps data of Japan has deteriorated. Users assume that the data source has switched, because the copyright attribution of Zenrin has disappeared.
  • Grab Malaysia and The Department of Geoinformation, of the Universiti Teknologi Malaysia, organise mentoring training for mappers valled Grab Geo*Star in order increase the interest of students in the areas of mapping and OpenStreetMap.
  • Mapbox reports that it enhanced its living map platform with proprietary data from Zenrin, a Japanese map publisher. It is not clear as to whether enhanced was used synonymously for “replaced OSM”.
  • It’s not just OSM that suffers from the occasional broken polygon. Simon Poole spotted woods near Zurich which have disappeared on Here and Bing maps.
  • The book Time for mapping: Cartographic temporalities deals with the entry of the temporal into maps in the digital age and contemporary mapping practices.
  • The children’s book Lindsey, the GIS Specialist introduces the basics of GIS. This is one of a small series published by the US-based surveying firm Bolton & Menk, based on the job roles of their own employees.
  • A Guardian quiz shows population density maps of various cities. Can you identify them? Or do you have to guess?.
  • Esri announces on their ArcGIS blog that the new March version (previously beta) of the OpenStreetMap Vector Basemap is now freely available in ArcGIS.
  • On the south coast of Norway the first underwater restaurant in Europe opened (automatic translation). Potential visitors have to wait half a year to get a reservation due to it being booked out. It is still only mapped as a construction site in OSM.

OpenStreetMap protest against Art 13 of the EU Copyright Directive 1 | © OpenStreetMap

[Actual Category]

  • Michael Reichert suggests turning off OSM services or adding banners to protest against the EU plan to implement the new, controversial, Copyright Directive. However, the question remains as to why the protest against EU politics is more important than existing or proposed restrictions of freedom elsewhere.

About us

  • The transfer of weeklyOSM to the FOSSGIS server and the subsequent necessary maintenance work has been completed. Users might have noticed some minor interruptions in service last weekend whilst this was taking place. We would like to thank Peter Barth and Andreas Hubel for the transfer. We especially want to thank Anthony Bennett aka @internetgeog of www.internetgeography.net for many years of administration of the site, which he has maintained exemplarily since 2014.

Mapping

  • Jan S proposes better differentiation between various kinds of police facilities. Jan has drafted a proposal and is seeking comments.
  • Members of the Polytechnic University of Milan (Politecnico di Milano) created a deforestation mapping wiki page to improve the understanding and mapping of land coverage to make analysis and visualisation of environmental issues such as deforestation easier.
  • Paul Allen asks whether superroutes are good, bad or ugly. In his post on the tagging mailing list he mentions some pros and cons of the controversial construct. During the discussion it was also asked whether relations of type=route containing child relations should be preferred over superrelations.
  • Antoine Riche pointed to undiscussed wiki changes about cycleway tagging which resulted in a long discussion about how to deal with oneway restrictions.
  • German mappers are voting on the deprecation of relations of type associatedStreet in Germany.

Community

Imports

OpenStreetMap Foundation

  • The minutes of the OSMF Licence Working Group meeting of 14 February have been published.
  • The OSM Operations Team announced on Twitter that one of OSM’s tile caches received a Denial of Service attack by someone using Amazon servers and an Load Impact User-Agent.

Events

  • The FOSS4G North America, an open geospatial technology and business conference, will take place from 15 to 18 April 2019 in San Diego, USA. The program is available on the conference’s homepage.
  • The next mapathon of MAMAPA will take place on 28 March at the Abendakademie in Mannheim. Beyond the humanitarian objective of the Mapathon, MAMAPA promotes the integration of new immigrants in Germany, in which locals and migrants map in tandem. Through the joint work prejudices and stereotypical thinking are reduced and mutual trust is strengthened.
  • The 7th (seventh!) annual conference organised by OpenStreetMap France will take place from 14 to 16 June in Montpellier (34), on the campus of the Paul Valéry University. Proposals for presentations in 5′, 25′, 55′ or even 2-hour workshops will be accepted until 15 April.

Humanitarian OSM

  • Russell Deffner calls for help with mapping flooded areas in Mozambique and Zimbabwe exacerbated by Cyclone Idai. More information about current tasks and how you can help can be found on the corresponding wiki page.
  • Nina Strochlic covers in National Geographic how the Bidibidi refugee camp in North Uganda is transforming into a permanent city. She points out how humanitarian mapping, HOT in particular, has helped in documenting the transformation and provided valuable data for planning and managing the quickly evolving area.
  • A story on MapGive, an initiative of the U.S. Department of State’s Humanitarian Information Unit, details how updated aerial imagery has helped crowdsourced humanitarian mapping. MapGive helped mapping efforts of Missing Maps in Uganda and Bangladesh by providing support with current imagery. The blog post shows differences in aerial imagery over the years and a before and after comparison of OSM data around refugee camps in Northern Uganda.

Open Data

  • The regional conference and conference on Latin American Open Data Abrelatam19 will be held at Quito from 28 to 30 August 2019.

Software

  • TriMet in 2009 launched the open source trip planner “OpenTripPlanner” that combines public transport transit with walking and biking. The tool, which can use public transport data in General Transit Feed Specification “GTFS” format and is based on OSM data, gained some popularity within the OSM community. The company announced a new version of its tool that can also incorporate data from Uber, SHARE NOW (formerly car2go) and BIKETOWN and uses real-time locations of vehicles and bikes to calculate routes. A beta version with data for Portland, OR, USA is available.
  • The Android app OSMTracker, which is popular with OSM mappers, no longer shows maps as a background to tracks. OSMTracker uses the generic user-agent from the osmdroid library which was recently blocked by the OSM Operations Team. The tile usage policy requires application-specific user agents.
  • Fabian Kowatsch, of HeiGIT, announced that the HeiGIT Big Spatial Data team published a public world-wide instance of the ohsome OSM History Analysis Platform including an API, an updated dashboard and the beta prototype map interface ohsomeHEX (OSM History Explorer). All this allows you to analyse the evolution of any OSM tag for arbitrary regions and time periods in a simple way. Several examples are given in earlier blogs which now can be adapted for arbitrary regions around the world. Ideas for further enhancements are most welcome.

Releases

  • Version 5 of Openrouteservice was published. The service, developed by The Heidelberg Institute for Geoinformation Technology, bears the name of the Jupiter moon Io.

Did you know …

  • … the OSM Software Watchlist (release status) by Wambacher? It has been extended to cover another 15 OSM applications.
  • … the tagging of a centre turn lane? This is described using the tags lanes:both_ways= 1 and turn:both_ways = left.

Other “geo” things

  • Dr. Michele M Tobias asked #gischat on Twitter “Can you tell your GIS/mapping career story in one tweet?” Read the nice stories and please tell your OSM story as well. 😉
  • As Marius Watz has tweeted, the Norwegian municipality Trysil decided not to name streets but numbered thousands of cabin buildings instead. The website nrk.no reported that the step caused chaos for tourists, desperate cottage owners and emergency services.
  • Bryan Housel asks for help to “link branded businesses in OpenStreetMap to wikidata”.
  • The Guardian reports on desire lines: “illicit trails that defy the urban planners”. (Note: there is a small amount of data in OSM identifying such paths, see 1 and 2).
  • In an article on Medium, Caitlin Dewey covers the story of the Fruit Belt neighbourhood in Buffalo, New York which had been replaced on Google Maps by something called “Medical Park”. The article follows the residents and their investigation into how Google may have acquired inaccurate neighbourhood data from Pitney Bowes and how that came to be. She also points out how little control the community had over the mislabelling. In comparison, the neighbourhood had only been added to OSM a few days ago with plenty of room for map improvements in the area.
  • Jorge Andres, a volunteer cartographer for MapAction, discusses, on their corporate blog, how to most effectively represent topographical relief when mapping volcanic hazards. He suggests that 3D visualisations are more effective, and in 2D contour lines tend to obscure significant details.
  • Tom Lee, Mapbox’s lead on policy, testified before the US Senate Judiciary Committee regarding privacy law reform.
