There is a nice initiative going on in our local community.

1) Fill "name:etymology:wikidata" within for all streets named after a person.

2) Match this data with Wikipedia’s data, especially whether that famous person is male or female.

3) Show the % of streets named after male or female characters.

OSM is great at reflecting sophisticated opening hours grids.

Here is a park with varying hours along the year.

opening_hours=Jan 1-Mar 31 09:00-17:00; Apr 1-May 31,Sep 1-Sep 30 09:00-18:00; Jun 1-Jun 30 09:00-19:00; Jul 1-Aug 31 09:00-21:00; Oct 1-Dec 31 10:00-17:00; Jan 1 off; Dec 25 off

Every now and then, we find this: a new user in OSM abusing the "name" tag. (User created patches of grass and a cycle track and described what they are… in the name tag.)

This is probably because iD has a prominent box for the name tag for almost everything.

I routinely make Overpass queries to spot mistakes like this in my area. Seems I will have to add more queries (e.g. a patch of grass AND a name → warning).

Simple hack for here to an everyday problem.

I was trying to reorder bus route relations. It’s a long road with a complicated layout. JOSM will show you the same name multiple times, it’s an error-prone situation.

My solution: renaming the ways by adding a prefix. Then, ordering the routes becomes quite simple.
Do not forget to restore the names before uploading the changeset.

I am sharing this story, in case it might be useful for someone.

London Underground logo in Brussels?
No, merely the Transport Layer with a roundabout (tram tracks across a roundabout, bus route in the roundabout).

The Region provides accurate numerical imagery under an ODbL-compatible licence. This made it possible to upload most buildings in our city several years ago.

Yet, new buildings are typically hand-drawn. More complicated than it seems.

Aerial picture is taken from an angle, which the mapper should compensate, and the roof may hide some details. Moreover, iD default to Flanders imagery, which has a lower resolution than ours.

This picture shows the typical offset.

The same station after I mapped it with .

1) Walk everywhere across the station, shoot a video
2) Draw a structure on paper for every floor
3) Align station structure on items visible from aerial imagery (stairs)
4) Filter out everything else (roads, houses) with JOSM
5) Create a box with 90° angles (the triangle ruler icon)
6) Duplicate the ways of that box: they will become tracks, platform edges, stairs, footways…
7) Make it routable by tagging everything properly: levels, etc.

Most metro stations were built in the 1970s and 1980s, sometimes using a very simple structure (two underground floors, everything is symmetrical, both left/right and front/back).

An interesting challenge for technical drawing fans…

I like small regular improvements StreetComplete provides with every update. This time, my favourite enhancement is no longer asking for the surface tag for highway=steps when those are in fact... escalators.
I created many such ways when drawing metro stations and those quests were annoying.

I think this problem affects many mappers in the world: there are countless things we wish we could improve… but sometimes we forget to keep track of everything we have opened.

There will be significant changes on network as from Monday.

I take great pride is making sure information in OSM is always up-to-date.

The good news is that—despite being usually recomputed quite infrequently—the Transport Layer was updated and already shows the new routes.

Ever heard of "pareidolia"?
This is a psychological tendency to see familiar objects or faces at places where one shouldn’t. (Think of Rorschach test too.)

Who sees a robot here?

There is a new park in . I made sure to add it to the map.

Each time I create an area with 'leisure=park', I feel anxious that other mappers might mistake me for one of those -Go players.

But this one really exists, folks. 😎

Just added a hedge inside a roundabout.

Rendering in OSM Carto is funny, it looks like a smiley. 😄

Today I taught two new users about how to map urban areas.
We are lucky to have recent detailed aerial imagery here.
This is an area we improved in only a few minutes.
