How many hours do you map? [¹] | © Jennings Anderson |

Mapping

Mappers in the German OSM Forum > and on the Talk-de mailing list > discussed how to deal with the floods in Western Germany. Damaged roads which will stay impassible for a longer time should be tagged as under construction or demolished. Buildings should not be edited/deleted for the time being. Road closures for a relatively short time and closures of passable roads should not be mapped.
Mark Altaweel took a look at map vandalism in OpenStreetMap. They describe what map vandalism is and what strategies are used to fix it or prevent it from happening.
If you map in Washington state it would be worthwhile reading jake-low’s diary entry on how to use the Department of Natural Resources LiDAR in iD.
MKnight questioned > some of the reasons given for voting against the leisure=bathing_place proposal (we reported earlier).
Philippe Lacour noted that there are now more objects in OpenStreetMap than people on the planet.
portalaventura asked > why Apple editors feel the need to bend streets.
User syntex shared a progress update on his quest to replace all the mapped buildings in Warsaw with outlines from a government dataset, BDOT10k.
Requests have been made for comments on the following proposals:
- cultivated=no/semi/fully to add sub-tags to natural=scrub that could be used to further refine these bushy areas based on objective criteria.
- tennis=wall to map tennis training walls, used to practise tennis shots without the need for an opponent.
- headlight=* for tagging when vehicle headlights must be used.

Community

How many hours a day do you map? Jennings Anderson investigated how much time mappers spend on the task and concluded that while some mappers might only ever make a single edit to a map, there are plenty of ardent, dedicated editors that map like it’s their job – and for some of these mappers it might be, but definitely not all.
Nama wrote, as Regional Director of HOT, about the foundation and activities of the (Mobile) Open Mapping Hub Asia Pacifik.

OpenStreetMap Foundation

To reduce mass downloads from tile.openstreetmap.org, in violation of the tile usage policy, the Operations Working Group has put an automatic block that filters the 0.001% users who cause 13% of the load.

Events

Ilya Zverev made > a HotWashUp on the SotM, mainly impressions and about his own activity.

Education

AngocA answered > JuanMelo’s question ‘how do I improve the map of Colombia?’.

Humanitarian OSM

HOT has opened applications for their Data Quality Internship. It is a three-month, full-time, paid opportunity.

The HOT Disaster Services Team has launched a new landing page featuring a detailed projection of the task areas they are focused on mapping. The new map display is powered by Kontur.

Maps

team2019alpaca is excited to have made a new map for visitors to the Steep Street Domain in Lawrence (New Zealand).

Software

Darkshredder gave an update, illustrated with screenshots, about his Google Summer of Code Project. The Nominatim Feedback Reporter will allow users to submit OpenStreetMap search (Nominatim) errors. These can then be added as test cases by the developers.

Releases

OsmAnd 4.0 (iOS) has been released. It adds new features such as snapping recorded routes to roads to enable better navigation, exporting and importing of settings, data, and maps between Android and iOS devices, and fixing freezing issues on CarPlay.

Other “geo” things

Liberty caps – or Psilocybe semilanceata – are psilocybin-containing mushrooms that grow naturally in many parts of the world. Are you interested in finding some of them in your neighbourhood? Just have a look to this ‘Magic Mushroom Map’.
prawo.pl reports > that 10 new settlements in Poland are proposed to gain city status on 1 January, 2022. Administrative boundaries of some municipalities will change as well. In the past year, place=city was promptly added by Polish mappers sometimes even before 1 January, however in many cases boundaries had to wait for official registers to catch up.
Rush hour in the Netherlands!
A digitally rendered map, derived from a vintage geological map of Australia combined with Digital Elevation Data (DEM), created by 4DMAPART, is making the rounds on Twitter.
