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.

Mapping

  • OSM South Africa are raising funds on GoFundMe to purchase historical topographic maps of Namibia. If funding is successful, the maps will be tiled for use in OSM editors, just like the topo maps of South Africa itself which are already available.
  • Peter Elderson wants to revive the highway=trailhead proposal from 2015. According to his post on the tagging mailing list, in the Netherlands mappers have added the tag at all starting points for trails which have some infrastructure (parking, information, etc). However, there is some confusion over whether the term trailhead is appropriate for the purpose and who is already using it in OSM.
  • Apple has posted potential data problems in Korea such as building-road intersections, highway links without classification and roads with excessively sharp angles to MapRoulette where the challenges can be solved by volunteers.
  • Apple announced that they will map buildings in Buenos Aires manually using imagery sources and GPS resources.
  • On Techcrunch.com, Jon Russell reports how Grab is jamming the OSM community in Thailand by making inferior changes. The article quotes a local mapper with the words “OpenStreetMap is mostly craft, but they [Grab] attack OSM with an industrial mentality”. The article also mentions that 100 employees of Grab’s mapping subcontractor GlobalLogic of India have become members of the OSMF.
  • Grab responded to the critical TechCrunch article: Bangkok mapper Mishari Muqbil provides an extended reply to Grab’s press release.
  • The German community continued their annual ritual and mapped Christmas market features that can be seen on the Christmas market map (loads slowly). The fact that the map is quite D-A-CH-centric may be a result of the insufficient translation of the wiki site but more likely relates to the German passion for this kind of market.

Community

  • Phase 2 of Community Africa Francophone for Open Data (CAFDO) mini-grants (automatic translation) funded various OpenStreetMap activities organised by members of local communities in Western Africa: a mapathon in Koutiala, Mali; one week of training in Zinder, Niger; mapping of tourism-related objects in Ouidah, Bénin; a three-day training dedicated to ladies in Ivory Coast; a promotional workshop in Burkina Faso and a conference for local authorities in Senegal.

OpenStreetMap Foundation

  • There are discussions in Australia to set up a local Open Source Geospatial organisation OSGeo Oceania as an OSMF local chapter.

Humanitarian OSM

  • The minutes of the board meeting of HOT US Inc. on December 6 have been published. The topics discussed during the meeting included the setup of an advisory board and the planned registration of a European branch in order to be eligible for EU programmes.
  • HOT announced a partnership with tech hub iLab Liberia and the local OSM community to introduce the Open Cities Monrovia project. As 90 percent of the population in Monrovia is living in areas with very high flood risk, the project aims to improve understanding of unplanned settlements and make the slum communities more resilient to natural disasters.
  • The project mamapa is teaching immigrants in Germany to contribute to international humanitarian mapping initiatives. The project, which is supported by BASF (Ludwigshafen) and CartONG, helps in a number of ways, i.e. assisting the activity of humanitarian relief staff on the ground, teaching immigrants new skills in geography and modern cartography, hastening their integration into German society and providing a directly appreciated humanitarian contribution.

Maps

Open Data

  • The Open Data Institute (London) announced four successful bids for funding under their local open geospatial data initiative. Two of these, maybe more, make use of OpenStreetMap data: in Oxfordshire local mappers and cycle advocacy groups will work with the council to improve cycle infrastructure, whilst Falkirk aims to improve access by community groups and individuals to a range of facilities.

Software

  • Stefan Keller announced (automatic translation), on the Swiss mailing list, an experimental tool for converting free text (German only) to the OSM opening hour syntax. Two different approaches are available for testing.
  • Fabian Schütt from the Statistical Office of the City of Stuttgart determined the walking time to the nearest public transport stop for every place in the city using the QGIS plugin OSM Tools from HeiGIT, which makes the functions of openrouteservice – such as routing, isochrones and matrix calculations – available to QGIS users.
  • Nils Nolde from Heidelberg Institute for Geoinformation Technology (HeiGIT) announced openelevationservice as a new endpoint within the openrouteservice API ecosystem. It queries a remote DEM for every vertex of a LineString or Point geometry and enriches those with altitude values. Ituses SRTM v4.1 as a start and you can easily test it using the interactive documentation in the API playground, even without programming.
  • Simon Poole provides some hints as to new features in forthcoming versions of Vespucci. Firstly, in a diary post, he explains how he has tiled OSM data for offline use in the editor. Secondly, he demos some work-in-progress on adding functionality to enable editing of turn restrictions.

Programming

  • Stephan Bösch-Plepelits made some changes to the Leaflet.TextPath library.
  • And here comes another little Christmas present from HeiGIT: In addition to their highly appreciated Python and R libraries HeiGIT Institute now offers an additional JavaScript API making it simple to use the openrouteservice ecosystem, covering the entire globe based on OSM, in web applications.

Releases

  • Find the changes in OSM Carto v4.18.0 here and OpenMapTiles v3.9 here.

Did you know …

  • this article from a year ago in which SeverinGeo explains why he thinks that the HOT US Inc governance should not to be replicated in the OSM Foundation.

Other “geo” things

  • Matthew Flint found an old, 1950s, town plan of Cardiff in a second-hand bookshop. It uses a very unusual radial grid for locating streets.
  • OSM contributor Mick Hicks tweets about how the extensive use of cul-de-sacs (dead-end streets) in suburban road layouts in the US over the past few decades makes the effective provision of public transport very difficult. He remarks both on his own observations from correcting TIGER data in Minnesota, and on recent press coverage of bus transport in Colorado Springs.
  • The BBC reports about account closures of Slack users who have ever visited a country imposed with US sanctions (e.g. Cuba, Iran, the Crimean Peninsula) or are citizens of such a country (via HOT mailing list).
  • The Guardian has a long article about Google’s commercial relationships with several US intelligence (spy) agencies. Google’s geospatial offerings, notably Google Earth, were a critical component in building this business.
