Breaking News

  • The OSMF Membership Working Group investigated the unusual signups in advance of the recent OSMF board elections. The MWG concluded that the signup of 100 employees of the Indian subsidiary of GlobalLogic, an outsourcing firm providing OSM/mapping services to clients like Apple and Grab, was an orchestrated and directed campaign and that the applicants did not sign up voluntarily, personally and individually. The MWG expressed concerns that it was a possible attempt to influence the OSMF board election. The full report details all facts found during the comprehensive analysis of the signups. The report, which has been made available by Guillaume Rischard on the OSMF mailing list, has been sent to the OSMF board in advance (2018-12-26), but the board has not yet taken a stance on it. Also, the company GlobalLogic has not provided comment yet.

Mapping

  • Quite a few OpenStreetMap communities have responded to Facebook’s 10 Year challenge by showing how OSM has developed in 10 years:
  • Saeed Hubaishan challenged the table in the OSM wiki that shows the *_link type for roads that connect different highway types. The following discussion revealed that it seems there is no documented consensus and *_link roads are mapped more intuitively. The Wiki table mentioned was marked as not generally accepted during the discussion.
  • The OSM wiki says that the level tag for buildings is defined as a 0-based-index i.e. the ground floor starts with a zero. However, Tobias Zwick found a lot of buildings that have probably been mapped with a one-based-index in mind. There exist different conventions across the world how levels are numbered.
  • OSM UK has selected mapping of places in UK Food Standards Agency Hygiene Rating System as the 1st quarter task in 2019. This OSM wiki page explains how.
  • In his OSM diary Andres Gomez Casanova exhibits (es) his bicycle gear. He is using the equipment for 360-degree photography for Mapillary in Bogotá, Colombia.
  • Peter Rukavina explains in his blog how he created missing features in OSM and updated existing ones while he was linking anything with a geographic location from his blog posts to OSM.
  • François Lacombe’s proposal for additional attributes on pipeline and waterway valves has been approved.

Community

  • [1] Pascal Neis’ s mapper information How Did You Contribute now shows whether a mapper is an “active contributor” in accordance with article three of the Contributor Terms. An active contributor is allowed to vote in the case of a licence change and is eligible for the new OSMF fee waiver program.derFred questions the term “active mapper” as it is defined in the OpenStreetMap Contributor Terms and proves this with three impressive examples.
  • Jonah Adkins reports a couple of important items from the board of OSM-US. SotM-US will be held in Minneapolis in September, and as of January 2019, they do not have an Executive Director. Apparently, the person hired and the organisation proved to be “not the best fit for each other”.
  • 889 mappers who have been active in North Korea at some point received a direct message from Wonyoung asking about their mapping motive. The message is discussed in the German forum (automatic translation). The correspondent for weeklyOSM in Korea LuxuryCoop has taken care of the matter on that site.

Imports

  • Sloppy mistakes during the import of building data in Canada have led other mappers to demand stopping the import and thinking about reverting. For now the import has been put on hold.

OpenStreetMap Foundation

  • Martin Koppenhoefer reminds the board that they were going to come back with some responses on the topic of Crimea. Heather Leson promised to respond “within the week” on January 7th.

Events

  • As the number of mappers steadily increases in the region around Louvain-la-Neuve in Belgium, a first meetup will be organised there on February 11th to get to know each other.

Humanitarian OSM

  • The Red Cross Belize helps their Government with disaster training, procurement of equipment and OSM training to better understand risks and how to respond to those risks.

Education

  • OpenSchoolMaps, an initiative of Swiss OSM for promoting open maps in education, announced a new education package for creating thematic online maps with uMap and a workshop about open maps and the open source software H5P, that can be used for creating educational material.

Maps

  • Maarten Hermans wrote a guide on how to query data from OSM, process the data with R’s sf and dplyr packages and interactively display the result on OSM and historical map backgrounds using Leaflet or as a WMS web service. In his example he was looking for roads with “gangen” (Dutch name for small historical passages within the inner city) in their name and displayed the result in OSM and historical maps after he processed the data.

switch2OSM

  • Quique Pernas provides a twitter thread explaining the usefulness of Osmhydrant.org for foresters and other fire fighters.
  • The search engine DuckDuckGo changed its maps from Mapbox to Apple Maps.

Software

  • The premium version of the Blender-OSM plugin has been released!
  • Fabian Kowatsch, from HeiGIT, explains how to use historical OSM data from the ohsome API to compare different regions based on their attribute completeness over time with a simple API call. He uses the tag surface=*. for streets as an example.

Releases

  • OSM’s main map style, Carto, has received another update. As the maintainer Daniel Koć wrote in his OSM diary, version 4.19.0 has added the rendering of boundary=protected_area and revised it for reserve boundaries. The new version also added more barrier icons and support of amenity=vending_machine and improved a lot of other things.

Did you know …

OSM in the media

  • A news article from the publisher Heise repeats (de) (automatic translation) the position of a forest owner who blames online maps, which allow users to share information, for being partly responsible for unfettered biking in forests and thus causing problems. The one-sided article repeats the demand for a ban on providing online geospatial information about the property of a third party.
  • Teresa Jolley pointed in a tweet to a video interview with Brian Prangle from OpenStreetMap UK about the question as to whether the public sector should make more use of OSM.
  • A collaboration between the Belize Red Cross and the American Red Cross made it to the local news on Channel 5 Belize according to a tweet from Belize GEO.

Other “geo” things

  • Richard Fairhurst’s New Adlestrop Railway Atlas has been appreciated by fans of old railways from around 2004 when it first appeared. However, it never covered the whole of the British Isles. Certain minor distractions in the ensuing period (including Potlatch, Potlatch2, cycle.travel, tilemaker) have limited additions. Now Richard hints at a completely new edition.
  • GBIF (Global Biodiversity Information Facility) has analysed how much of its data on the location of biological organisms originated from citizen scientists. The answer is over 500 million records making up more than 50% of the total.
  • As Andy Mabbett wrote in his mail to the talk mailing list, the ARIADNEplus Project, a new European initiative for Digital Archaeology and Cultural Heritage, uses OpenStreetMap to display the locations of its records.
  • A number of German media outlets (public Radio Deutschlandfunk (de) (automatic translation) and ARD’s Tagesschau (de) (automatic translation)) reported about Google Maps’ inability to calculate even simple routes between Palestinian towns but, on the other hand, how Google can easily provide routes in the same area if the destinations and sources are Israeli settlements.
    The reports close by saying that the locals help themselves with “other mapping apps that are kind of Wikipedia”.
  • Kashmir Hill of Gizmodo elaborates on the dilemma of a South African family living in Pretoria, for whom imprecise IP geolocation services regularly bring uninvited guests accusing them of internet-related crimes. If it happened in South Africa, it supposedly always happens at the coordinates of their property.
  • Atlas Obscura reports about David Garcia’s cartographic representation of the 100 largest islands summarised in one chart.
  • The German IT publisher heise.de reported (de) (automatic translation) possible problems with older GPS devices on April 6th, due to a “week count rollover” in the GPS system. The week in the GPS system is encoded with 10 bits and hence, it can only address 1024 weeks. The last rollover was in 1999. As the system will be changed and the resolution of the week counter will be increased to 13 bits, the next rollover will be in 8192 weeks.

Mapping

  • The tagging mailing list has been very busy recently. The voting for four proposals has been started.
    • The key crossing:island=* is intended to indicate the existence of a pedestrian island at a road crossing.
    • The keys prepaid_top_up=*, prepaid_top_up:brand=* and prepaid_top_up:network=* can help in finding a location where you can buy a top-up card for your phone.
    • If you want to specify whether a power line is insulated, you might be interested in the optional key insulated=yes/no.
    • If there is a railway on a highway and this space is shared with vehicles, the new tag embedded_rails= will allow you to tag the highway, although the rails are mapped as separate ways.
  • One question that is regularly asked is the difference between waterway=ditch and waterway=drain. Eugene Podshivalov asked this question on the tagging mailing list and it became apparent that there is not yet consensus on the differences.
  • The city of Cologne, Germany, released (de) (automatic translation) its recent aerial images under a CC0 license and offers WMS services that can be used with OSM editors.
  • Konrad Lischka shows (de) how to query for selected information from OpenStreetMap with the Overpass API and how to visualise it with uMap using churches and church service times as examples (automatic translation).
  • Christoph Hormann continues his ironic recommendations on how to map for the renderer, specifically how to render arbitrary text.

Community

  • Ben Abelshausen is advertising for Open Belgium 2019, a conference that will take place on March 4th in Brussels. In his mail he invites everyone to submit a talk and announces the availability of early bird tickets. He is also promising to organise a community day later this year.
  • Martin Noblecourt mentions job offerings from CartONG on the talk-fr mailing list. The French NGO is looking for a trainee, a Missing Maps animator and more.
  • Martijn van Exel announced the release of a new MapRoulette version. Version 3.1.2 is now available in Japanese too. It allows you to share filtered result lists with others and to edit just the current object in JOSM in areas with a lot of data unrelated to the task at hand.
  • The Centre de Cultura Contemporània de Barcelona (CCCB Lab) features an article from Carlos Bajo where he explains how OpenStreetMap contributes to societal development in places where the government fails to provide basic services. He highlights the growing number of local contributions in Africa and the benefits of Open Data and OSM in particular.
  • A discussion in the German forum (translation) asks whether Mapbox are “taking over tagging sovereignty in OSM”.

OpenStreetMap Foundation

  • Guillaume Rischard announced that the new Organised Editing Guidelines have come into effect. The guidelines cover “edits that involve more than one person and can be grouped under one or more sizeable, substantial, coordinated editing initiatives.”
  • derFred points (de) to the possibility of becoming a member of the OSMF without the regular membership fee of 15 GBP if you cannot afford membership due to economic reasons. If you are an active mapper you can apply for the Fee Waiver Program. You can also apply if there is no payment option for the membership fee available for you (automatic translation).

Events

Humanitarian OSM

  • Pete Masters thanks HOT Tanzania for helping a hospital in Tanzania to implement a patient origin tracking system by mapping the surroundings and training of the hospital staff. The system is intended to help the hospital locate the source of a disease and it is hoped that it might help to prevent the spreading of diseases and infections too, according to the website ippmedia.com’s reports.
  • Janet Chapman posted a review of 2018 for Crowd2Map, an initiative aiming to map Tanzania, in her user diary. She mentions the invitation to organise a mapathon at the UN, the award the organisation received at the last State of the Map in Milan and some of the talks she held during the year. Further information can be found on Crowd2Map’s website.

Education

  • The new curriculum (pdf) for French high schools states that all students should be introduced to geospatial data usage. One of the expected abilities in that domain is the ability to “contribute to OpenStreetMap in a collaborative way”.

Maps

  • [1] The website openstreetbrowser.org received an update that makes more detailed filtering for buildings available and now includes filters by building attributes such as type, age or height. The new map version also introduced office tags in thematic maps and provides more detailed popups in the Culture categories.

switch2OSM

  • A short tweet about an event in the headquarters of the Ordnance Survey, the national British mapping agency, about “Road Flows” led Richard Fairhurst to ask for more details. The event was about using OpenStreetMap for improving data quality. In addition, the answer revealed that the Ordnance Survey searches for road direction mismatches between their own and OSM data and then sends surveyors to verify if required.

Software

  • Many software projects use the fork and pull model approach for contributions. alexkemp explained the basics of this model in his OSM user diary after he faced this requirement for the first time when he wanted to update a Github-hosted project.
  • Mapillary has just released a desktop application for uploading large amounts of street-level imagery, which can then be used for editing OpenStreetMap. It is currently available for Mac and Windows. Learn more on the Mapillary blog.
  • Adam Rousell from the Heidelberg Institute for Geoinformation Technology reports that the latest version 4.7.2. of openrouteservice also includes information about access restrictions when your route takes you over roads that are marked in OSM as restricted (e.g. destination only roads, private roads etc.).

Programming

  • Karry explains how he wrote his own hillshade tile server for his project OSM Scout for Sailfish OS, a project to bring offline OSM maps to Sailfish OS, after the previously used hillshade tiles from Heidelberg university stopped working.
  • Reddit user nanothrowaway airs a lot of grouses about OsmAnd’s OSM Map Creator. Various redditors tried to explain why the data is kept in memory for efficiency reasons, but the OP maintained that it’s the use of Java which is the problem.

Releases

  • MyOSMatic, a MapOSMatic instance at osm-baustelle.de, has upgraded the front end from Bootstrap v3 to v4.

Did you know …

  • … you can use Traveltime Platform to create isochrones in several countries? One can create travel time polygons on a map, for example, “how far can I reach within 30 minutes by car/bicycle/public transport from my current location?”
  • … the always up-to-date OSM Software Watchlist?
  • outdooractive.com with OpenStreetMap maps?

OSM in the media

  • The German weekly newspaper Die Zeit uses OSM data to visualise (de) the distribution of various sports (from cricket to football) worldwide (automatic translation).

Other “geo” things

  • Matt Caywood, of Washington(DC)-based firm TransitScreen, announced the launch of OpenMobilityData – “the OpenStreetMap of transit” – a joint venture with non-profit MobilityData. The goal is an open data platform for transit and mobility data. The data have been seeded from TransitFeeds, which has been acquired by the new venture.
  • The Hindu, the second most circulated English-language newspaper in India, published an article about OSM, the OSM community in India and the use of OSM in the humanitarian sector.
  • The BBC World Service’s Business Daily programme aired an episode (select the download link on that page) devoted to the poor availability of modern up-to-date maps across Africa. This is the third episode titled “Africa’s Missing Maps” and mainly features businesses such as TomTom and the Ordnance Survey.
  • Maxor Technologies, DigitalGlobe’s parent company, announced that the WorldView-4 Earth observation satellite has suffered a defect in its attitude correction system. Due to this loss of a stability axis, the satellite can no longer be used for image acquisition. WorldView-4 was launched in November 2016, making it the youngest satellite in the DigitalGlobe fleet. SpaceflightNow reports that the planned lifetime was 10 to 12 years.
  • The British Guardian: “Off the chart: the big comeback of paper maps“.
  • Aaron Straup Cope writes about how the term “airport gates” has multiple meanings (for passengers, airlines, aviation authorities) and how this affects where they should be placed on maps of airports.
