Mapping

  • Frederik Ramm tells the talk mailing list about a large redaction of names and administrative boundaries in North Korea following a request by the copyright owner, 38north. He also warns not to use Wikipedia or Wikidata as a source for restoring these names, as we don’t know whether their contributors obtained the data from a suitable source.
  • Robert Whittaker announced two new tools to improve OSM data in UK only: Ghosts and survey me!.

Community

  • Darafei Praliaskouski who sponsored the tile rendering server- vial, since 2016, seeks for someone interested in sponsoring this server, because he can no longer afford it.
  • Reddit user jongeheer asks the OSM community for input on an open world game pack addition for GTA, he’s creating based on OSM data. See the demo.
  • "More than 75,000 schools were imported into Peru", dannykath wrote in her OSM diary about the process of importing the schools in Peru and how it benefits the community.
  • Researchers from the GIScience Heidelberg group published a paper in the open source journal Open Geospatial Data, Software and Standards describing an IT infrastructure that can be used to collect and evaluate data about the OSM project.

    Besides classical data sources such as the Planet OSM, the OSM Wiki, etc., other more or less OSM-related data, such as OSM Stats and Natural Earth is also included. The result is various data sets that were published in a standard container format.

    Various visualizations of the acquired data are available:

    • Geographical visualization of changesets depending on time
    • Graphic of the most common English words in the tag descriptions in the OSM wiki
    • Animation of the development of OSM tags over time
    • Presentation of the correlation between first use of an OSM tag and first documentation of the tag in the OSM Wiki
    • Visualization of daily activity in OSM

    This data and the presentations are intended to provide a more comprehensive insight into the OSM world that has been possible in previous studies, which focused more closely on either social aspects or the evaluation of data.

OpenStreetMap Foundation

  • The minutes of the OSMF board meeting on May 24th have been published.

Events

  • [1] SotMFR 2018 in Bordeaux 01.-03.06.2018

    • Here is the program of the SotMFR 2018 which took place last weekend in Bordeaux.
    • The videos of the SotMFR 2018 are available.
    • Odette Aïda MENDY presents initiative of OSM contributors in Senegal to map transport / bus lines in Dakar.
    • Aimée SAMA presents the community OSM Togo : its birth, its activities and events and its projects. You can download the presentation. She announces also the end of the first day 01/06/18 of the SotMFR in Bordeaux with many contributions from French-speaking Africa.
    • Vincent Bergeot asks the speakers from Bordeaux to submit their presentations.
  • Stefan Keller tweets some preliminary results of his work on identifying "Areas of Interest" using OSM data, which he will report in the academic track at SotM-18.

Humanitarian OSM

  • Researcher of the Harvard T.H. Chan School of Public Health published a paper in the New England Journal of Medicine examining the number of victims of the Hurricane Maria in Puerto Rico in September 2017. According to official, but controversial information, the hurricane killed 64 people.

    The researchers selected around 100 out of the 900 barrios in Puerto Rico, which are small administrative units with an average of less than 5000 inhabitants. For the sample of households, the authors randomly identified 35 buildings from the buildings on an OSM map in each of the approximately 100 barrios. The data for the selected buildings were downloaded from the Overpass API, the centroids were calculated and converted into Geospatial PDF files. The files along with an OSM base map were copied to the Samsung Tab A 7 tablets of the on-site interviewer.

    Based on the surveyed households’ data, researchers estimate that 62% or 4,645 more people died in the post-hurricane period than in the same period in the previous year. For the researchers, it is likely that the actual number is higher, as their values ​​are affected by the survivor bias.

  • Following the mapping of Hidroituango dam in Colombia, previously marked as high-risk for flooding, OSM Colombia asks experienced mappers to start validate the new data.

Maps

  • Netzwolf announces (de) (automatic translation) in the German OSM forum to disable the data updates for historic.place and is looking for someone to take over the data supply for the historic.place in his place.
  • Railway platforms with covered=yes are no longer rendered and the first group of mappers is starting to remove this tag. This could be seen as mapping for the renderer. The word covered can be understood in different ways, so it was not a good choice for a tag to begin with. Maybe we will understand it as: you stand under something, out of sun and rain. The wiki apparently describes it as: it’s under another object or underground and can’t be seen from the air.

switch2OSM

  • The team behind OpenMapTiles launched a map hosting called MapTiler Cloud with weekly updated OSM data, customize tool and hosting for own geodata. The free plan is available also for open-source and open-data community project websites.

Licences

  • The Italian city of Bologna has publicly released a TMS with aerial imagery of the city, for the first time by default with an addendum to the CC BY 4.0 which explicitly refers to OpenStreetMap (English version at the bottom).

Software

  • The French company Magellium annouces on talk-Fr the magOSM service to access thematic OpenStreetMap datasets as WMS/WFS services available for metropolitan France. A Web map is available here for download. Source code will be opened in the next weeks.
  • HeiGIT demonstrated how to use the OSM History Analytics platform ohsome for OSM Street Network Topology Analysis and Disaster Activation Monitoring ISCRAM paper.

Programming

  • Uber released a new geographic visualization toolbox under the MIT license. The software is meant to help Uber gain insights from the combination of map data with POIs and millions of GPS points. kepler.gl is a web application for large amounts of data. It is based on the visualization solution deck.gl, also from Uber. It is meant as an improvement over the tool chain QGIS, Carto and Mapbox Studio and it makes use of Javascript with React, D3.js, and Three.js for visualization.
  • Microsoft aquires GitHub for US$ 7.5 billion in stock.

Releases

  • Version 3.0 of OsmAnd is released. Some of the improvements include:

    • integration of travel guides from Wikivoyage.org
    • improved presentation of Wikipedia content
    • map markers import
    • improved rendering of GPX tracks

Did you know …

  • … that JOSM’s PT_Assistant plugin now comes with a new double split map mode, which makes it easy to add bridge, tunnel , traffic_calming=table and bus_bay? Everything that involves splitting a way at 2 nodes and assigning tags to the middle part. Polyglot describes this new functionality — added by Biswesh Mohapatra as part of his GSoC project — on the wiki.

OSM in the media

  • Following the Google Maps pricing policy change, « Le Monde » published an interview with Christian Quest (spokesman for the French OSM local chapter). Open alternatives like OSM are needed more than ever.
  • The Tagesspiegel shows (de) (automatic translation) where new cycle paths are planned in Berlin based on OSM.

Other “geo” things

  • Arstechnica reports that georeferencing of emergency rooms brings spam from personal injury lawyers to patients in the US.
  • Mapbox announced a partnership with Foursquare. It will add 105 million points of interest to their database.

Mapping

  • Gaurav Thapa from OSM Nepal asks on the talk list about mapping more metadata for schools. The answers examine the new metadata (students’ and teacher’s statistics especially) but suggest to store them elsewhere, for example Wikidata, that has specific support for such historical statistics.
  • Mateusz Konieczny opened the discussion to revise the good practice of «Don’t map temporary events and features». The issue edges on the frequency of occurrence (weekly, monthly, yearly…).
  • Polyglot proposes role=reverse to indicate on a bus route that the vehicle needs to reverse out, in order to exit narrow dead end streets. It is not expected that this role will see much use, as this is extremely uncommon along the public transport routes, but the role would elegantly describe what is going on.
  • After some discussion on the tagging mailing list, it became clear that the English term «roundtrip» has a different meaning to one that many people had expected it to have. The English word «round trip» resembles «rondreis/rondgang» (tour) in Dutch or «rundfahrt» (guided tour, race stage) in German. It seems the contributors to the discussion can agree on a new tag circular_route=yes for routes that return where they started (or very close to it) and maybe closed_loop=yes/no for QA purposes when all the ways in a route relation form a closed loop.
  • SunCobalt questions and analyses the increasing Data Working Group user blocks. He seems concerned that there may be too many such blocks, but it could be just as well that growth in user numbers also brings along more users with undesirable behaviour.

Community

  • CityLab reported on a mapathon aimed at public transportation by University of Maryland students.
  • Baran Kahyaoglu demonstrated the Mapbox Unity SDK with a Civilization game style real world map. Watch it on Youtube or read some comments on Reddit.
  • Alban Vivert, OSM France community member and CartONG NGO volunteer, started his cycling Andean cartographic itinerary at the beginning of May. Follow his South American adventure (es) (fr) with an interactive map of the project, GPS traces (with elevation profile), and contributions to Mapillary.
  • Tyrallová and Harald Schernthanner presented (de) a practical introduction to OpenStreetMap in a science day. The participants learned how to record geodata on their smart-phones and PCs and then prepare and upload it to OSM. In addition to this ‘hands-on tutorial’, it was demonstrated that the data can be used, for example, for pedestrian navigation. The slide deck (de) is available.
  • Nicolas Chavent publishes a Twitter moment that shares pictures from the two weeks of organizational-governance-tech workshop related to OSM and free Geomatics in Lomé (Togo) targeted to OSM community trainers from Benin, Burkina Faso, Ivory Coast, Mali, Niger and Togo with the support of the International Organization of Francophonie (OIF).
  • Rene78 recounted a choice encounter in Myanmar while travelling a path he arm-chair mapped in preparation for his travels.

OpenStreetMap Foundation

  • The minutes of the IRC meeting of the OSMF Data Working Group on May 10th have been published.

Humanitarian OSM

  • Faults in the reservoir of Hidroituango could precipitate a flood in the Lower Cauca, Colombia affecting 12 municipalities. OSMColombia’s project 108 endeavours to map the affected area and help emergency agencies measure the possible damage. Please help if you can.

Programming

  • daniel-j-h from Mapbox writes about implementing reasonable alternative routes in the Open Source Routing Machine’s Multi-Level Dijkstra mode.
  • Rafael Troilo from HeiGIT gives a short overview of the access layers of the OSM History Analytics platform ohsome with the new OSM History Database OSHDB.
  • hesidoryn reported his progress in implementing the OpenStreetMap API using Go language from Google Summer of Code 2018.

Releases

  • Gisgraphy 5.0 is available. It allows forward and reverse geocoding, auto-completion, interpolation, location bias, find nearby, street search for vehicle tracking. All is open source and can be run offline (local installation), though some hosted services are also proposed. Some importers are using a consolidated database from open datasets (OpenStreetMap, OpenAddresses, GeoNames, and QuattroShapes); to prepare the next version, David Masclet asks for people that have already worked with Tiger data to help to code its importer.

OSM in the media

  • The Economist writes about the OSM volunteers coordinated by OSM-DRC that map the North of the Democratic Republic of Congo to support humanitarian organizations in the field that fight the progression of the Ebola outbreak.
  • CBC-Toronto published a podcast (and transcript) about the coordinated efforts of DRC government, World Health Organization (WHO), United Nations, Doctors Without Borders and OSM volunteer mappers to provide a more reliable map of the Democratic Republic of Congo, currently affected by an Ebola outbreak.

Other “geo” things

  • Brian Tomaszewski presents his experience in the Zaatari refugee camp in Jordan, empowering displaced people by teaching mapping and GIS skills.
  • An article in Pacific Standard magazine states «Inaccurate beliefs about climate change and flood risk could crash housing prices in the next 20 years, according to new research by American economists.»
  • Sasha Trubetskoy created an accurate transit-style map of the ancient Roman roads of Italy, based on the rich historical record on the topic.
