Mapping

  • Jochen Topf introduced a new QA tool called Osmoscope. He wants to avoid the drawback of current QA tools, which is that the person who operates the tool decides which layers are shown. With Osmoscope running on a web server, a user can add QA layers by entering the configuration i.e. a URL that points to a description of a new layer. In other words you create a GeoJSON with possible OSM issues and add it to Osmoscope which takes then care of visualisation. If your GeoJSON contains thousands of potential issues, you should think about using vector tiles. A proof-of-concept implementation is available at osmoscope.jochentopf.com. Issues can be reported on GitHub.
  • Joseph Eisenberg wants to render radio telescopes but noticed that what he considers the “possible tagging mistake” man_made=radio_telecope is used over 200 times while the “correct tag combination” man_made=telescope with telescope:type=radio is only used twice as much.
  • Bren Barnes is asking for suggestions for his proposal to introduce amenity=research_station.
  • The new tag telecom=* was accepted and now enables mappers to add last-mile networks and related equipment like DSLAMs.
  • In Belgium the law was changed to add “School streets” (nl) (automatic translation). These are streets adjacent to the entrance of a school that are shut off from all traffic except for pedestrians and bicycles around the times the schoolday starts and ends.

Community

  • User marc marc started a lengthy discussion on the tagging mailing list by pointing to the topic that crossing=zebra, which is assumed to be a shortcut for crossing=uncontrolled + crossing_ref=zebra, prevents mappers from adding crossing=traffic_signals for crossing with zebra and traffic signals.
    However, a much bigger tagging problem became apparent during this discussion: The maintainer of the OSM editor iD adds or removes tagging presets he is “tired of hearing people complain about”. Keeping in mind that one can control the way people edit if one controls the presets in an editor that accounts for roughly 50% of all uploaded changesets, the change of a preset should not be controlled by one or a few developers.
  • Michael Spreng introduced (de) (automatic translation) the new design for the Swiss OSM website. There is still some work to do, such as translations, but it already looks promising.
  • Melanie Eckle announced that HeiGIT/GIScience (de) from the University of Heidelberg and German Red Cross signed a Memorandum of Understanding to strengthen their strategic partnership to conduct joint activities related to research as well as development of GIS technologies, skills, workflows and communities.
  • User cbeddow has started OpenStreetMap Montana, and is seeking mappers from all parts of the state to join and plan local meetup events.
  • The Mapper of the Month October 2018 as chosen by OpenStreetMap Belgium is Aylin Kızılaslan from Turkey.
  • The Wikimedia Foundation has started the call for proposals for the wishlist 2019. WMF is open for ‘feature requests’ from the OSM community.
  • An interesting chart labelled ‘Community OSM’ was drawn by Simon B. Johnson during the GeOnG conference as reported in a tweet by Paul Uithol. Common mappers, who go out surveying rather than tracing aerial images, might have difficulties finding themselves in the chart.

Imports

  • Pieter Vander Vennet announces on the imports mailing list that the Belgian community plans to integrate building footprints from multiple Belgian governmental sources into OSM. The plan is to include external IDs in the import, which received loud criticism as well as support. As it’s more of a slow integration effort, rather than a bulk one-time import, which depends on said external IDs to work efficiently, the plan is to still include them.

OpenStreetMap Foundation

  • OpenStreetMap Belgium, the newest local chapter in the OSM family, introduces itself in a blog post.
  • OSM’s local chapter in the UK responded to the Geospatial Commission’s call for evidence. OSM UK supports the efforts to use public and private sector geospatial data more productively. They believe that OSM plays an important role in that area. The whole response is linked to at the end of the blog post.

Events

  • Chetan Gowda announced that the SotM Asia will take place in Bengaluru (a.k.a. Bangalore), India on November 17-18. Don’t forget to register!
  • The community day at the FOSS4G SotM Oceania 2018 will be on Friday, 23rd November. The programme for the day was just announced.
  • Registration for FOSS4G Oceania (20–23 November 2018, Melbourne) is open.
  • Geofabrik usually organises two or three hack-weekends each year in their own offices. Christine Karch tells us in a blog post (de) (automatic translation) that the most recent event had to switch to a larger location at Karlsruhe University, as 9 people joined to plan the next SotM in Heidelberg, plus 7 JOSM developers seized the opportunity to meet face to face and discuss long-standing issues.
  • As part of the non-profit project openminds.at, the Austrian Open Source Award (de) (automatic translation) will be presented for the second time on November 9. An Open Source Ball will take place afterwards.
  • OSMF’s new Belgian local chapter is planning their first official meeting during the week of November 13th.

Humanitarian OSM

  • The United Nations Population Fund reports how Crowd2Map Tanzania is using OpenStreetMap to fill gaps on maps in rural Tanzania to end Female Genital Mutilation (FGM).
  • A short summing-up shows HOT’s preliminary conclusion after 3 weeks of its Hacktoberfest. HOT thanks everyone who has worked on issues related to usability and experience of the Open Source tools, performance, and general bug fixes.
  • There are several Missing Maps events around the globe during November where you may want to participate.

Maps

  • Gastronomy objects will no longer be displayed by small icons in zoom level 17 but by orange dots as they often created a visual clutter.

switch2OSM

  • Recreation.gov combines campsites and facilities from 12 US federal government bureaus, allowing users to search and make reservations. Until recently, search results were displayed on a Google map, but the new website includes a makeover with OpenStreetMap and Mapbox as the basemap.

Software

  • We have reported before rescues of hikers occasioned by the use of OSM without evaluating the terrain by other means, such as topo maps. Now, according to CBC Canada, a hiker had to be rescued by helicopter from the top of a cliff in British Columbia. Allegedly the hiker was benighted because they relied on Maps.me for an estimate of how long it would take to walk in the mountainous terrain. An issue was reported in 2017, but it is not entirely clear if the situation still exists with the current version.
  • The world’s most visited cemetery is Père Lachaise in Paris. Super Lachaise, an iOS app, allows you to easily find historical monuments and prominent graves.

Programming

  • Rémy Mathieu wrote a blog post titled Rendering a map using Go, Mapbox and OpenStreetMap where he explains how to retrieve and draw map data. He plans to write another article as he aims to finally render fantasy styled maps.

Releases

  • JOSM release 14382, version 18.10 is out. The enhancements include a new option to show the object version in lists, an increased default overpass wizard timeout, the cut of overlapping GPX layers when merging, the MapCSS function is_similar and many minor improvements.
  • QGIS 3.4, the first long-term release of version 3, has just been published. New expression functions and code completion for the expression builder have been added to this version.

Did you know …

  • netidee is the largest Open Source Internet promotion in Austria. netidee stands for openness, transparency, and sharing. The results of all funded projects are available to the public for use and further development (“open source principle”).

Other “geo” things

  • [1] Mapping London wrote an article about a map that shows the modelled 2020 annual pollution levels of NO2 based on data from the London Atmospheric Emissions Inventory 2013 (LAEI). The map was created using Mapbox’s 3D WebGL libraries and is client-side rendered.
  • Garmin continues its famous GPSmap series with the Garmin GPSmap 66s. The German biking website gpsradler.de has published (de) (automatic translation) a test of the new GPS handset.
  • The map for historical items at gk.historic.place is now linking to the US National Register of Historic Places (NRHP).

Mapping

  • Dabohamda announced in a tweet (fr) the creation of the first bus line in Conakry following a field survey. OpenStreetMap Guinea will complete the bus network in the coming days. (automatic translation)
  • Satoshi Iida (User nyampire) announced last week on Twitter(1, 2) (ja) about fresh aerial imagery for Japan. OSM now has permission to use aerial imagery published as open data from Nerima-ku (specified districts in Tokyo Metropolis) and Fukaya city. He created map tiles and explains how to use them on the wiki Nerima-ku (ja) (automatic translation) and Fukaya (ja) (automatic translation). The imagery is of very high resolution, which will help us to enrich OSM.
  • Martin Koppenhoefer asks on the mailing list whether the decision of the Data Working Group regarding the Crimean peninsula should be changed. Russia has been in control of the area for four years and changes are not expected.
  • Frederik Ramm of the DWG warns on the Talk-de (de) (automatic translation) mailing list and in the German forum (de) (automatic translation) that users who continue to participate in verbal fights in changeset comments of new users against or for ‘gluing’ landuse areas to other features will be temporarily blocked from editing. He also started a discussion (de) (automatic translation) about this topic to try and resolve one of the oldest contentious issues in OSM, i.e. the gluing of linear features to area features. Mappers pro gluing don’t want to leave blank artefacts in between when rendering at high zoom levels; mappers against find it is extremely time consuming to do further editing when glued together.
  • Researchers at Cardiff University have used OSM data to develop a novel method for finding the safest routes for pedestrians. Their work is to be published in the journal Accident Analysis & Prevention.
  • Joseph Eisenberg suggests bringing some order to the tagging of hot springs and geysers. The current tagging goes back to a proposal from 2008 that was never approved.
  • Gregory Marler presents the 360° cameras which are available for hire from OSM UK for its members in an unboxing video on YouTube.
  • With a mail to the tagging list, Allan Mustard draws attention to the proposal about distinguishing embassies from consulates. The aim of the proposal is to bring structure to the current set of informal tagging rules, to let OSM reflect international law.

Community

  • The user Adrian O´Connor shares a tweet about the launch of OpenStreetMap Ireland at Maynooth University. Ciarán Staunton (aka DeBigC) reports the founding of OpenStreetMap Ireland, which aims to become the local chapter of the OSMF in Ireland.
  • Simon Poole has submitted a pull request that will add links to new OSM Terms of Use in the Welcome box and on the About page.

Imports

  • An import of natural monument trees in the Italian region Friuli Venezia Giulia is planned. Giovanni has created a wiki site and is looking for help.
  • Leif Rasmussen announced a ready-to-go import for missing buildings and address data in Miami-Dade County.
  • update An import of electric charging station for cars in Norway, Sweden and Finland is currently in preparation. As outlined in the wiki page, electric charging stations are quite important in Scandinavia as nearly 50% of all cars sold in Norway are electric cars or plug-in hybrids.
  • While most imports are carefully prepared, documented and discussed, some aren’t. As reported on the Canadian mailing list, a mapper added administrative boundaries in a questionable way and ignored comments from community members.

OpenStreetMap Foundation

  • The draft meeting minutes for the License Working Group meeting of October 11th were published.
  • The meeting minutes of the recent OSMF Board have been published.

Events

  • Opensaar e.V., a German FOSS organisation, will host a meet&talk on November 15th at Saarbrücken in Germany. In addition to talks about OGC standards, Mapserver, Postgis and QGIS, Guillaume Rischard (OSM: Stereo) will talk about the experience with open geodata in Luxembourg.

Humanitarian OSM

  • The OSM GeoWeek will take place between November 11-17th. OSM GeoWeek is a celebration of geography and map making with OpenStreetMap. Last year there were 230 events in 48 countries. The homepage of the OSM GeoWeek helps you to find or register an event.
  • HOT endorsed the Principles for Digital Development, which comprise nine guidelines designed to help digital development practitioners integrate established best practices into technology-enabled programs.

Maps

  • The association “Atvirasis žemėlapis” (The Open Map) together with SpatialForces released a topographical vector map of Lithuania. The map combines OSM data, the SwissTopo style with some minor adjustments and LiDAR based dynamic high resolution hillshading. Further details are described in a blogpost.
  • XCTrails Map provides a dedicated map for climbing routes fully based on OSM data.

Software

  • OsmAnd seems (de) (automatic translation) to partially meet the needs of firefighters, but favourites with links to PDFs (e.g. floor plans) would be very helpful. A user is looking for help in the German OSM forum.

Programming

  • Coder superDoss provided a pull request for iD, that enables it to read and display data in shapefile format.

Releases

  • Daniel Koć announced the release of OpenStreetMap Carto 4.16.0, that brings a bunch of new icons and renderings. There have been a few comments on why ATMs and post boxes are now rendered only at zoom level 19+, and the discussion on the list indicates that it was not a simple decision.
  • Please check the OSM Software Watchlist of Wambacher for the latest releases of all OSM software.

Did you know …

  • … about the possibility to use (de) (automatic translation) mailing lists as a forum?

Other “geo” things

  • A visualisation of rivers in the US based on their average annual flow has been posted on reddit.com/r/MapPorn.
  • The blog on singletracks.com, a site dedicated to mountain biking, has published a test of the outdoor GPS Wahoo Elemnt, that uses OSM maps.
  • The website geospatialworld.com published an article about the increasing importance of satellite imagery for journalism. Aerial views have become indispensable for journalists who want to double check the location of a scene, document deforestation, illustrate devastation of urban areas in recent conflicts and many other purposes.
  • The World Food Programme posted an update about the situation in Nepal. The region suffers from extreme food shortage on a large scale. An OpenStreetMap-based pilot project on trail and infrastructure mapping in the Jumla district concluded in September.
