Mapping

  • A fool with a tool…” (… is still a fool) is probably not the right subject line if you want to address an issue on an international mailing list, even if you encounter an OSM element where name spacing is taken to an extreme level:
  • Disputed boundaries are a sensitive issue, and so are proposals as to how to map them. John Paris announced version 1.6 of his proposal for mapping disputed boundaries in OSM and requests feedback.
  • Konrad Lischka suggested extending the tag amenity=kindergarten with operator=, operator:type=charitable and organisation= to properly tag kindergartens that are operated as independent charitable entities.
  • Following the recent approval of the new key interval= for tagging the time between departures at any given stop (see Headway on Wikipedia), Leif Rasmussen continues with the next step and suggests the key departures= for adding the departure time for a given interval.
  • Minh Nguyen reports about his mapping of Oldenburg (Indiana), a city where street signs are in German.
  • In some countries the number 13 is considered as unlucky. In these countries the 13th floor is often omitted in multi-level buildings. The mapper ‘This Is A Display Name Desu’ asks how to deal with it when mapping building levels.

Community

  • A community representative from the Thai community will meet with the mapping lead from Grab to discuss recent quality issues caused by Grab’s activity. Mishari Muqbil is helping to prepare for the meeting and asks for input from the wider community on what topics should be addressed during the meeting.
  • “What use is OpenStreetMap?” John Whelan was asked by an employee of a municipal government. How would you have responded and where would you refer them to find further information? The answers to his question might help you too.
  • The interpretation of population limits in the OSM wiki for choosing the correct value for a place= tag led to a dispute between mappers in Turkmenistan. The issue is that the importance of a settlement in some countries is not reflected in the same way by the population number as it is in Western Europe for example. Joseph Eisenberg wrote a good summary of how to distinguish between the place-values without using hard population limits. Kevin Kenny reports on a similar discussion in the US and points to the outcome.
  • David Garcia, a cartographer, wrote an article on medium.com about why he is committed to the commons of cartography. As he lays out in the article, his turning point was his humanitarian contribution to OSM after the devastating cyclone Haiyan.

OpenStreetMap Foundation

  • We want to repeat a tweet from the OSM Operations Team: “Thank you to @AssoGrifon 🇫🇷 and @iwayAG 🇨🇭 for offering us Tile CDN servers today. Both now up & already serving traffic.”
  • The German company Alpha9 Marketing Gmbh Co KG with its brand auskunft.de joined the OpenStreetMap Foundation as a Bronze Corporate Member.

Events

  • The 4th GeoPython Conference will take place on June 24-26, 2019 in Basel/Muttenz, Switzerland. The topics range from Python in general, geospatial webservices and geovisualisation to indoor mapping and modelling

Education

  • Yongyang Xu, Zhong Xie and Liang Wu from the Faculty of Information Engineering, China University of Geosciences, Wuhan, China, have analysed the road network in OSM and found out that the data in OSM is highly detailed and complex but also includes many duplicate lines which degrade the efficiency and increase the difficulty of extracting multilane roads. The team suggested a machine‐learning‐based approach to predicted multilane roads. Unfortunately the study is behind a paywall, hence, it could not be confirmed whether the research area has indeed many duplicate roads or if it is a misconception about OSM’s data model.

Maps

  • Scott Davies published a nicely styled Chronological Map of Walthamstow on Twitter that he made with OSM, QGIS and inkscape.
  • Paul Norman offers pre-rendered OSM carto tiles at low zoom levels for download. The files that are available for the zoom levels 0 to 6, 8, 9 or 10 could be useful, if you need a world map without high zoom levels and don’t want to set up a database server.
  • Juminet has created (fr)(automatic translation) an OSM map of the Ardennes region. He describes a clever method to determine orientation for markers, and shows the special attention his map gives to Christmas trees.
  • An interesting study about street names in Germany won an award at the Information is Beautiful Awards.
  • OpenSnowMap points out that a number of cross-country ski trails in the Jura are yet to be mapped in OSM.

Software

Releases

  • Version 2.12.2 of the iD editor has recently been released. The new version allows a preset to control the “add field” dropdown, improves usability and performance, fixes a lot of bugs, adds localisation to label/description pulled from Wikidata, and further improves the presets.

Did you know …

  • … about get-map.org, a tool to create printable maps?
  • … how to run your own instance of uMap? A user asked in the forum and was pointed to a step-by-step guide.
  • … that Austria’s building coverage in OSM has reached 85 percent? That’s an increase of 21% compared with the beginning of 2016. Even the least-mapped municipalities exceed 50 percent coverage.
  • … Geofabrik’s tile calculator, that returns the number and size of tiles in a given bounding box.

Other “geo” things

  • The theory that the geography of a country determines its development is not new. However, Lionel Page disagrees and points to a road map of the border area between the neighbouring countries Finland and Russia, that shows significant differences although they are very close to each other geographically. To the critics that said one example does not falsify a theory, Lionel responded by naming similar examples in North/South Korea, Austria and Czechia (the Czech Republic), USA and Mexico.
  • Frost & Sullivan, a global business consulting firm headquartered in Mountain View, California, has chosen Mapbox’s mapping and live location platform as 2019 Platform of the Year.
  • The company Here, formerly known as Navteq and Nokia Maps, launched an app for planning and sharing rides called SoMo (derived from “social mobility”). The app aims to combine all public, private and personal transport offerings in a single system and adds social functions to share rides between personal contacts.

Howto … OSM Promotional Leaflets 1 | © alexkemp, Andy Allan

Mapping

  • OpenStreetMap Ireland suggested a mapping task for the holiday period: adding all the buildings for a single townland. A few mappers (including Ciaran, Earl and Tshedy), had a go, but this may be another multi-year project for Irish mappers as there are over 60,000 townlands.
  • Simon Poole (CH), Christian Quest (FR) and sebastic (NL) performed their customary New Year’s Day edits to update boundaries of communes following mergers.In Belgium it was a group effort, for which preparations had already started back in June, as it involved many street name and building address changes.
  • Daniele Santini suggests adding a top_up=* attribute to a feature if it sells top-ups, for example for mobile phone credit recharge vouchers, over-the-air credit top-up, public transport credit recharge vouchers or credit recharge for prepaid credit cards.
  • Markus proposed a new value for the place key, place=peninsula , for mapping named peninsulas. During the discussion it became obvious that the tagging list is more in favour of natural=peninsula, a proposal declined back in 2008. The discussion also provides some useful information for people interested in philosophical questions, e.g. what is the upper size limit for a peninsula, or what is the difference between a cape and a peninsula?
  • Hufkratzer challenged the wiki description for building=pavilion as being a building providing facilities for users of sports grounds. However, he learnt that the description is fine according to British English, the language we are using in OSM. The question as to whether the term was wisely chosen if it means different things in other countries was not asked.
  • eteb3 was looking for a tag for the planter bike rack that appeared in the UK recently and is double checking if there are any unwritten rules or things to consider before using own values. After the discussion our wiki has one more documented tag: man_made=planter.
  • Axelos suggested implementing some kind of hierarchy for route relations. Others have pointed him to the similar, already used concept of super-routes / super-relations, something that has been very controversially discussed.

Community

  • In Kozikhode, India a team of volunteers is working hard to create a comprehensive digital map of the wards of Koorachundu Grama panchayat using OpenStreetMap.
  • Reddit user tseepra created a nice visualisation of the 70k nodes, 60k ways, and 160k polygons that were added over 2018 in Ireland. In the Reddit thread there is a discussion of how this was made using the QGIS Atlas feature.
  • Peter Elderson is currently working on sectioning very long route relations into relation parts with less than 300 ways. The basic idea is to make such relations more workable by splitting them into sections of one day’s walking. However, he is looking for someone who can help him to create sortable wikitables on a wiki page which are fed from a live query.
  • Wille Marcel, a GIS application developer from Brazil, has been elected as mapper of the month by OSM Belgium. He discovered OSM back in 2010 at an open source software conference and names the development of OSMCha as his biggest achievement.
  • Simon Poole has updated the contributor statistics for 2018.
  • CouwelierTim published a weekly chat summary of the discussions in the Belgian community from December 17th 2018 through December 23rd 2018. We hope you make yourself familiar with CouwelierTim’s weekly offering as we will not publish a regular reminder as part of our weekly digest.

Imports

  • omgitsgela requests comments for the planned statewide import of addresses in Massachusetts. The import of data from MassGIS, the public GIS database of the state, is comprehensively documented in the wiki.

OpenStreetMap Foundation

Events

  • The website for Open Belgium 2019, a conference for Open Knowledge and Open Data, is now online. The conference will take place on March 4th, 2019 in Brussels.

Humanitarian OSM

  • HOT published a series of videos about the Humanitarian OpenStreetMap Team webinars in 2018 and gave an outlook on the already scheduled webinars in 2019.
  • HOT is asking for proposals to improve the Tasking Manager. The update will enable the Tasking Manager to incorporate results from machine learning, including a validation and deconflicting process before the model output is pushed to OSM.

Maps

  • Larissa Vernier, an epidemiologist from Doctors without Borders, explains the motivation behind her choice of R for Epis (R4Epis) for her work. One reason is the spatial analysis functions, which help her to look for patterns, understand how fast a disease is spreading and decide on a plan of action. It would save a lot of valuable time if all epidemiologists could standardise on a single free software solution.
  • Mapbox is, no doubt, seeing a lot of maps over the course of a year. On their website you can find 18 maps with some background information of the maps that inspired them during 2018.
  • On his user diary alexkemp reports that he ran out of the OSM Promotional Leaflets he had received from Andy Allan. Hence, he tried to get the GitHub-hosted leaflet printed at his local print shop but they did not have the necessary fonts. In his post he describes his journey to get the required fonts.
  • The maposmatic instance on osm-baustelle.de is now offering an overlay style that renders allotments=plot.

Open Data

Software

  • Florian Schäfer announced a new command line tool that can convert between the i18n file formats and the custom format used by JOSM. The new tool langconv is part of the gradle-josm-plugin.
  • The OsmAnd team reports on several nice features and improvements they added over the past year and what we can look forward to in 2019.

Releases

  • A new stable version of JOSM has been released. Version 18.12 fixes memory leaks and outdated imagery entries, provides an animated “Getting Started” page with shining stars 15 days around Christmas and contains a lot of other fixes and improvements.

Other “geo” things

  • UnoSat created a map of the inundated areas caused by the tsunamis in Lampung province, Indonesia.
