EU upload filters and ancillary copyright

  • The proposal to reform the EU copyright was originally suggested by Günther Oettinger during his time was the EU Digital Commissioner (2014-2016). The EU’s controversial reform, may introduce upload filters and ancillary copyright. It also has only a very limited exception for text and data mining. A key hurdle was passed last Wednesday after the majority of members of the EU parliament voted in favour the proposal, with only slight modifications.Many online communities protested against the proposal in the hope that the EU Parliament would decline it again, as they did in July 2018. The concern is that the new law will require all parties in the EU to implement upload filters, i.e. censorship infrastructure and as such, it will become a big hurdle for projects with user-generated content like OSM or Wikipedia.Wikipedia visitors in many EU countries were met with a black banner, urging them to defend the internet, and some Wikipedia editions were shut down completely showing only a black protest message. OSM in Germany with its local chapter FOSSGIS participated in this protest by replacing every tenth tile with a protest message on a black background. The OSMF Board did not take a stance on the matter although there was and still is some noise on the OSMF mailing list.The new copyright law still needs parliamentary approval before it will become law. By passing the draft, the EU parliament opens negotiations with the European Council and the European Commission. If, as currently expected by the lawmakers, this version of the law will be approved by all three EU bodies, it could be ready for a final vote by the end of the year.

Mapping

  • Osmose now allows potential errors to be exported as KML files. You can import these files into apps, such as Maps.me, to assist in checking on the ground.
  • The Osmose QA tool now includes a layer with traffic signs from Mapillary where the equivalent information is missing from OSM. At the moment, the layer is available in France, Brussels and parts of Germany.
  • The question as to whether waterway=riverbank is an ‘old scheme’ and should be replaced by natural=water + water=river was discussed on the tagging mailing list.
  • On the tagging mailing list, terraced buildings – rows of houses with shared walls – were discussed.
  • Andrew Wiseman from Apple’s mapping team started a project to help improve the road networks of Senegal, Côte d’Ivoire, Tunesia and Uganda and he asks the local mappers on the respective countries’ mailing lists where to direct his team’s attention.
  • Telenav created MapRoulette tasks for highways in OSM lacking a speed limit, but where data are available from image recognition processing of OpenStreetCam photos. So far the new Maproulette challenge is limited to Detroit.
  • A reddit user asks whether tools exist that semi-automatically trace buildings from images. The answers included pointers to Microsoft’s buildings footprints, RoboSat from Mapbox and the JOSM plugins building tools, Lakewalker, Scanaerial, Tracer2 and mapathoner. However, you should make yourself familiar with the Automated Edits code of conduct.
  • Harry Wood re-iterates Christoph Hormann’s call to double check multipolygons. As reported osm2pgsql is repairing fewer errors than it did before it was updated. Now errors are just rejected: leading to gaps on the map.

Community

  • The OsmAnd team launched a short survey, asking if you know about their in-built Travel Feature, which uses data from Wikimedia’s Wikivoyage project.
  • OSM is becoming a multi-generational project. Florian Lohoff’s son, born when he joined OSM in 2008, has now also started contributing to OSM.
  • A bicycle enthusiast from France created tutorial videos (automatic translation) explaining the many features of OsmAnd in French. English documentation can be found on the official website.
  • We reported earlier about a quality analysis tool written by Pierre Béland and used to analyse 12 African cities. The tool has now been used to analyse 25 Tasking Manager tasks from August. Maps by each contributor allows rapid visualisation to detect those buildings that need to be revised as a matter of priority. Once again there is variability in the quality of building geometries and the number of topological errors. This analysis suggests we need better monitoring tools to follow up on the work done at mapathons by inexperienced mappers.
  • Tigerfell wants to rewrite the Relation-Template for the wiki. He explains his motivation in a blog post and is inviting you to participate.

OpenStreetMap Foundation

  • A new server, named pyrene, was added to our tile rendering cluster. It is located in the OpenSystems Lab, based at Oregon State University, Corvallis (USA), and should reduce tile latency for North American users.

Events

  • The FOSS4G Belgium Conference will be held on October 25, 2018. The organiser, OSGeo.be, just announced the continuation of the annual conferences that started in 2015 and is calling for papers, maps and sponsors.
  • The FOSS4G SotM Oceania, a joint conference of OSM and FOSS4G communities of Australia, New Zealand, and the Pacific Islands, will take place in Melbourne on November 20-23, 2018. The organisers are looking for open geospatial projects for the community day on the last day of the conference.

Humanitarian OSM

  • [1] HOT announced the launch of Visualize Change, a tool that can create an embedded and downloadable visualisation of the changes in OSM over time. The tool was shown to the public at the recent FOSS4G.
  • CartONG, a French NGO, is looking for (fr) (automatic translation) someone willing to apply for a civic service (fr) (automatic translation) position. Missions include planning and hosting mapathons, taking part in the operations at CartONG and raising the awareness of new audiences.
  • Janet Chapman is organising a Global Mapathon from 28th to 30th of September 2018 to help end female genital mutilation (FGM).
  • Luc Kpogbe from OSM Benin reports that they are mapping their northern border region and the city of Tanguieta. They are training young mappers and are able to provide them with smartphones thanks to a micro-grant from HOT.

Education

  • Marena Brinkhurst and Jinal Foflia, from Mapbox, together with Yves Barthelemy, of the Zanzibar Mapping Initiative, and Nuala Cowan, of Open Cities Africa, hosted a 2 day hackathon in Zanzibar following the FOSS4G event in Dar-Es-Salaam.This resulted in:
    • tools for comparing imagery (2 islands of Zanzibar were flown over with drones to create fresh high resolution imagery)
    • interacting with crowd-sourced data
    • visualisations of school enrolment, urban development, and flood prone areas
    • an interactive tour of cultural heritage sites in Zanzibar

Maps

  • It looks like many users originating from Western countries have a problem with the “main map” on openstreetmap.org as they are only familiar with the Latin script (we reported earlier). Sven Geggus explained in detail how he copes with localisation in the German map style on openstreetmap.de. Specifically, he makes notes about proper tagging, what one should care about and which problems might arise. In addition, he presents a feasibility study in case OSM.org should one day be converted to vector tiles.

Open Data

  • WeeklyOSM often receives links to papers about OSM in science journals that are unfortunately closed source and – except for the abstract – behind a paywall. The EU and some national research funders have announced a plan to make research papers free to read. The new policy will be implemented from 1 January 2020.
  • The saga of non-open addresses in the UK continues. Owen Boswarva summarises the current position as the national Geospatial Commission gets up to speed.

Software

  • cartONG, a French NGO, prepared a comparison between the three commercial UAV post-treatment applications: Pix4D, ESRI’s Drone2Map and AgiSoft.

Programming

  • Andrew just announced the release of AgentMaps, a Javascript library for building and visualising dynamic social systems on maps.
  • Simon Poole has added a function to OSM that provides a file with a list of deleted user account UIDs. Most of those user accounts have been deleted as they were used exclusively for spamming. Pascal Neis’ tool How did you contribute is already making use of the list.
  • Sabrina Marx, from the Heidelberg Institute for Geoinformation Technology (HeiGIT), published a step by step tutorial in a Jupyter Notebook on analysing HOT Tasking Manager projects using the ohsome API.
  • OSM user Glassmann documented his approach to generating a vector tile overlay for use in iD in his OSM diary.

Releases

  • Wambacher’s OSM related software list has been updated. Most recent version changes were Komoot Android, Mapbox Nav SDK , Mapillary Android, Naviki Android, QMapShack and Vespucci.

Did you know …

  • JungleBus, an Android mobile app that makes it easy for beginners to collect bus stops all around the world.
  • OpenBeerMap, it allows the user to specify their favourite beer brand and then displays pubs offering it on a map. The question of whether the beer brands offered in pubs merit being added to OSM is more contentious though.
  • … the Christmas map, where you can already start adding events like Christmas markets?

Other “geo” things

  • Randy Meech (ex CEO of Mapzen) outlines, in a long twitter thread, the philosophy behind his new business, Street Cred labs, which is developing new approaches to capturing POI data. Of particular interest are his remarks about how the data may be licensed. TechCrunch has written a short article about the company.
  • From time to time people use OSM to add fantasy locations. The medieval fantasy city generator might help people who are looking for a nice looking fantasy map.
  • The Open Geospatial Consortium (OGC) is looking for comments on the draft Geospatial Artificial Intelligence (GeoAI) Domain Working Group (DWG) Charter, that is intended to provide a forum for discussion and aims to ensure interoperability of OGC standards in AI applications.
  • The Guardian reports that sheet 440 is the worst selling map in the OS Explorer series (1:25k), covering an area of over 800 square kilometres in the far north of Scotland with a population of less than 200, and ‘a few dozen’ buildings. The best selling map, of Snowdonia, is 180 times more popular. OS surveyor Dave Robertson also explains how new roads are mapped – not much different to how we do it in OSM.

Mapping

  • The city of Stuttgart allows OSM to use its aerial imagery, which has a ground resolution of 20 cm. This step was discussed with the local OSM community during the last local OSM meetup where the city representatives also asked what data could help OSM further.
  • On the tagging mailing list Joseph Guillaume introduces his proposal for canal=qanat; these are underground channels for conveying groundwater.
  • On talk-GB Microsoft asked for help with some unnamed roads that they have identified.
  • [1] Nick Johnston wrote a blog post about mapping Britain’s paths in OpenStreetMap. He includes much background information on public rights of way paths, He got the data for the paths in his home region Gloucestershire from Rowmaps and surveyed using OsmAnd with the tracks in the background. Even if you have no intention to map paths in the UK, just the pictures of his beautiful home region make the article worth reading. He ends his article with the warning that you should not import the data straight away for a number of reasons.
  • User MKnight has refined (automatic translation) the reservoir Lac de Petit-Saut in French Guiana in weeks of hard work. He also summarises the negative environmental consequences of the dam. (de)
  • OpenSnowMap.org’s maintainer yvecai has compiled up-to-date statistics about ski pistes in OSM. The combined length of all ski pistes in OSM exceeds 100 000 km!
  • Land parcel data in OSM is mentioned in a study about the impact of spatial data on the development of slums in cities with rapid urbanisation. According to the report, OSM has not reached a consensus as to whether parcel-level data should be mapped due to concerns about data quality, validity, and maintainability. The same applies to metadata on parcel data. It also mentions that mapping parcel data is becoming more common.

Community

  • We recently wrote about Matthias Plennert’s article “The social construction of technological stasis: The stagnating data structure in OpenStreetMap” in the journal Big Data & Society. The article in general and one of the key points in the article, i.e. that hidden gatekeepers would be responsible for technological stagnation in OSM, caused some discussions. The author responded to the feedback in a special article.
  • Noémie Lehuby, Florian Lainez, Flora Hayat and Jocelyn Jaubert have revamped the OSM France website. This was also discussed on the Talk-Fr mailing list. (fr) (automatic translation)
  • MySociety, a UK-based non-profit organisation, providing technology, research and data to help people become active citizens, is looking for worldwide electoral boundaries. David Earl forwarded the query to the OSMF mailing list.
  • A lot of text about Facebook and its contribution to OpenStreetMap has been written recently. LukeWalsh’s article provides a new perspective on it. He wrote about his experience during the college rotational program, when his placement was at the Facebook department, which makes OSM contributions.
  • The Kosovo community now has a Kosovo-wide Telegram group. Recent topics include open data and the naming of things in an ethnically diverse country. All mappers from anywhere in any language are welcome.
  • United States ambassador to Turkmenistan, Allan Mustard (OSM apm-wa) wrote two articles about his work on OSM, currently the best map of Turkmenistan available to the general public. As you can read in one article, being an ambassador has the advantage that you can use the head of the Motor Roads State Concern as a QA tool. In his second article he gave some insight into his tour to a southern Balkan Province in Turkmenistan where he updated road information and collected POIs, GPS traces, and Mapillary pictures.

Imports

  • Andrew Harvey plans to import buildings in the Australian Capital Territory into OSM and started the required discussion on the import mailing list. The import would add over 60,000 buildings with over 500,000 nodes to OSM but does not include address data.
  • The import of road network data is planned in Kerala, India, a region affected by severe flooding recently. The data was generated by Facebook making use of machine learning. The plan is to allow Facebook’s mapping team to do the initial import, after which the OSM-India community will validate the data. The local community requested Facebook’s assistance with this import. However, during the discussion it was highlighted that the import guideline was not followed exactly and some remarks were made.

Events

  • FOSS4G TOKAI 2018 (automatic translation) was held on Aug 24-25 in Tokai. The organising committee published the collected tweets (ja) of the event and published a video of the “core day” as well.
  • Mapping events will be hosted during OSM Geography Awareness Week on Nov 11-17, 2018 in several places around the world.
  • Michael Schultz from the GIScience Group at Heidelberg University invites participation in a validation mapathon on September 13 during EuroGEOSS in Geneva. The goal is to validate a forthcoming Landuse-Dataset that is being generated through fusion of OSMlanduse Data and Sentinel-2 Data using machine learning.

Humanitarian OSM

  • The World Bank is funding the improvement of OpenStreetMap-Analytics (OSMA) with new functionality through the project Open Cities Africa and the Global Facility for Disaster Reduction and Recovery (GFDRR). HOT reported at FOSS4G. The development, as well as the hosting of the project, is being carried out by the Heidelberg Institute for Geoinformation Technology (HeiGIT).

Maps

  • Laurence Tratt complains on Twitter that he can’t really read anything on the “official” osm.org map in those countries where no Latin characters are used. Laurence knows about openstreetmap.de, but looks for a map listing names in English (Munich, not München – or Milano = Milan and not Mailand. 😉 )Sven Geggus maintainer of the German style and the localisation code used there (available from here), thinks that a change from osm.org is barely possible with the currently used technology. However, in his opinion, this issue should also be addressed as part of the switch to vector tiles. In principle, however, the operation of an English version of the localised map would not be a big problem. Sven already runs a server for his employer’s projects.
  • OpenAndroMaps, a website for free Android vector maps, now provides additional information like peaks, capitals and ocean depths. The maker of OAM explains his motivation and gives some background information in a blog post.
  • Daniel Koć, maintainer of OSM’s main map style on osm.org, has written a second article about his personal design principles for the OSM Carto map style. It discusses why the size of a feature is the primary property considered for showing some objects earlier than others. The article also has hints on how to choose a proper zoom level for starting to show them.
  • Christoph Hormann addresses the possibilities of using patterns to mark different area types in his blog post “More on Pattern use in Maps”.

switch2OSM

  • The website wedemain.fr published (automatic translation) an article about how local authorities and administrations are using open-source alternatives to Google services. The recent change by the department Maine-et-Loire from Google Maps to OSM and other institutions mainly to Framasoft is discussed. The association Framasoft hosts many open source services, free of charge.
  • Gadgets360 published an article about some companies that have based their business model on free access to Google Maps. The article examines the trouble they are now in and provides some information on alternatives, including OSM.
  • etourisme.info recommends that Tourist Offices switch to OpenStreetMap and explains what other benefits this brings on top of the saved G-Maps fees. (fr) (automatic translation)

Software

  • An overview of important OSM apps for Mobile, classified according to purpose, was made for a mapathon event in Kinshasa.

Programming

  • Fabian Kowatsch from the Heidelberg Institute for Geoinformation Technology (HeiGIT) published a first draft of the documentation of the ohsome API, which is a REST API for analysing the history of OSM data through the OSM History Analytics platform Ohsome.org.
  • manoharuss gives a short introduction in his user diary on how to use OSMCha to find suspicious edits in OSM.

Releases

  • Simon Poole announced the release of Vespucci 11.1 BETA. The newly implemented features include:
    • improved preset handling
    • lookup in taginfo now happens manually for the recently introduced “auto-presets”
    • improved copy and paste of tags
    • more minor changes.

Did you know …

  • … the website autobahnkilometer.ch created by dktue? He has, according his announcement (automatic translation) in the forum, created this page to measure the current length of the OSM motorway network in Switzerland and to count the tagged motorway kilometres.
  • … the site share.mapbbcode.org that allows you to easily create and share maps with custom markers and geometries? You can invite others to edit or view your map. The site also provides [map] bbcode that is supported by some forums.
  • … the site mundraub.org? Originally used mainly in Germany, the user base of the site is expanding. The name “mundraub” means petty theft of food. The sites shares the location of plants, mainly fruit trees, that are freely available for harvesting by everyone.

OSM in the media

  • Our map was vandalised recently at a prominent location. As usual the offensive data was fixed after a very short time by volunteer OSM contributors. This time the data was corrected within two hours. Unfortunately Mapbox, whose maps are used by many companies including SnapChat, pulled the data for updating their maps during this two hour window. Hence the vandalism was visible to a very large audience and found a loud echo in the media with Techchrunch, BBC, Gizmodo, Buzzfeednews and many more reporting about it. In an official article OSM condemns this kind of vandalism.

Other “geo” things

  • Melanie Froude has set up an online tool that allows mapping of landslides. Dave Petley wrote a blog post about the new tool, where he mentions it’s still experimental. It provides a global and regional view of deaths from landslides. Both Melanie and Dave are from the Department of Geography, University of Sheffield. They also authored Global fatal landslide occurrence from 2004 to 2016.
  • As Eric Wilson reported on Twitter, the Russell Senate Office Building in the US was renamed to John McCain Senate Office Building on Google Maps after McCain’s death. According to the Washington Post it is not clear yet by whom and why the entry was changed. The name was later reverted to its previous version.
  • Agence France-Presse has published a map illustrating emergency medical care in France. All white areas are more than 30 minutes away from an emergency department.
