Organic Maps presented the results of their Subway Validator. This is a regularly updated status overview of all known networks. Networks with errors might be fixed directly in OSM with the help of the metro mapping guide.
roptat described > the different methods and apps for mapping by foot and car. He concluded that for him it is most efficient to collect as much information as possible and map later on a computer.
Florian Lainez pointed out that there is no need to update the coastlines dramatically changed by the Honga Tonga volcanic eruption. They have already been revised in OpenStreetMap using 30 cm PléiadesNeo imagery.
AngocA continued his series of articles about OSM notes. In one article > he described the different types of notes one may encounter, while in another > he lists several useful techniques for resolving them.
Littltebtc shared his thoughts about the new section of National Freeway 4 and Section of Provincial Expressway No. 74, opened just before the Lunar New Year Holiday in Taiwan. He said the Taiwan community’s mapping might not be perfect due to the newest satellite images not being available, resulting in some map mistakes after the National Freeway was opened to the public. He observed that the initial mappers of new highways might not check road connections to see if they are correct, warning there might be some risk if you solely depend on OpenStreetMap data for navigation purposes.
kubahahaha described > how he was updating bus stops in the GZM metro area (Poland) from a very old style of mapping the stops as nodes on the road.
Should private areas used for personal leisure activities be mapped using landuse=recreation_ground? This question > was asked on the German forum and provoked a lot of discussion.

After introducing a new routing engine (we reported earlier), OpenSnowMap now renders icons where something is tagged as piste:type=fatbike, aerialway=t-bar, aerialway=j-bar, aerialway=platter or aerialway=rope_tow.
Hoerli has > written instructions on how to display Google traffic information in OsmAnd.
Amanda described, in her OSM Diary, how to find OSM users who comment on changesets but don’t contribute by editing the OSM database. She used her anglosaxon tool, about which we reported earlier.

Martin Raifer released an update of iD’s tagging presets: Version 3.2.0 includes a lot of improvements, new presets and fields, as well as bug fixes and translation updates. Notable changes are the update of the parcel lockers preset to the new amenity=parcel_locker tag, and the addition of a preset for crossing=traffic_signals. See the changelog for the full list of changes.
Pieter Vander Vennet reported that MapComplete 0.14 has been deployed. Apart from lots of bug fixes and performance improvements, a new theme showing OpenStreetMap notes has landed. The filter function should come in handy. And of course, there are plenty of (new) themes, such as the street lighting theme (thanks Robin!) or the postboxes and -offices map (by nicolelaine).

Steve Coast showed us TomTom’s latest project named ‘RoadRunner’. It is used to automatically create maps based on vast amounts of GNSS traces. One-way streets and road classes are detected automatically. OpenStreetMap is used to provide street names. RoadRunner can be explored via their web application or you can download a PBF.
An article in The Guardiandiscussed the use of maps to illustrate literary works. Apparently James Joyce was adamant that no maps should be included in editions of Ulysses: perhaps he was worried people would try and draw routes avoiding pubs.
Only 11 days separate these 3 satellite images! The images are of Hunga Tonga-Hunga Ha’apai island, on which a volcanic eruption occurred two weeks ago. According to an article published by BBC News, NASA believes that the eruption was hundreds of times more powerful than the atomic bomb dropped on Hiroshima during World War II (the eruption is estimated have been equivalent to somewhere between 4 and 18 megatonnes of TNT).
