I went ahead and changed the area mapped here to `indoor=area` because it doesn't seem to represent the entire underground station. I encourage pixely to map the indoor areas corresponding to the other entrances, and to connect the indoor areas to both the upper- and lower-level platforms however they're connected IRL.

A diary entry seems like a good idea. This isn't the first time I've run into tagging disputes on underground stations. Perhaps documenting it will alleviate some confusion and provide a place to discuss and come to a consensus. I'll write one up soon.

Here's a more complete example that I've worked on in San Francisco: https://openlevelup.net/#19/37.78432/-122.40773

Once the data loads, try exploring the basement levels by clicking on the negative numbers on the right sidebar. The underground station building outline shows up based on the maximum and minimum levels given in its tags. The station is further subdivided into indoor areas, rooms, and railway platforms.

I've been mapping the excavated underground areas of subway stations as `building=train_station` + `location=underground`. There are a few examples elsewhere in the world of this tagging scheme being used (I'd link an Overpass query here but my home internet is broken right now and I'm on my phone). The default renderer seems to support this tagging scheme elegantly, having them show up underneath the surface-level streets and buildings.

My understanding is that these are train station buildings that happen to be underground, hence this tagging scheme. I'm curious to hear others' opinions and rationale though.

No worries. Thanks for changing it back.

As for trying to tag me in replies (as you mentioned in a private message), no need - I get an email notification for every reply to a changesets conversation I've participated in. I don't think OSM supports tagging users in changeset comments like that.

Hi JPinAR,

It looks like you've changed the names of various roads in Bentonville to numbers like 25, 35, 45, etc. Was this intentional? Are those meant to be speed limits?

Bonjour MapperNews,

Pourquoi avez-vous supprimé l'attribut `service=siding` de ces voies ? Elles fonctionnent comme évitements (sidings) et elles sont aussi nommé en tant que évitements.

Je vais annuler ce changement, à moins que vous n'ayez une justification.

To be fair, the Willis Avenue Bridge is movable, which precludes motorway classification IMO.

How often do the bridges over the Harlem River get raised? Is there a somewhat consistent schedule, or is it more of a once-in-a-blue-moon thing?

Click the "i" icon on the right sidebar for the map legend.

White Road is tagged as a track instead of a minor/residential road. In OSM, we have a distinction between dirt roads that only serve forestry and agriculture purposes (tracks) vs. dirt roads that serve residences and/or connect settlements (minor/residential road with surface specified as dirt). I think White Road should be changed to the latter since it seems to have residences along it.

The area also looks wooded, which may be a better match for natural=wood instead of landuse=grass. How come the buildings are deleted?

Hi CBratina,

your edit is live immediately and this road is now shown to the public as a dirt road. This is helpful for software that uses OSM as a backend - for example, routing software will be less likely to direct drivers down this roadway. However, I don't think the standard renderer shows roads differently based on their surface. Could you link to an example on OSM of a double dashed line you're expecting this to look like?

Reverted in changeset/96489307. Retagging these underground train stations to building=no + railway=station has introduced duplicate station objects with labels, and doesn't match up with how underground buildings are mapped elsewhere; see https://overpass-turbo.eu/s/11Cc

Hi LQconcern and welcome to OpenStreetMap!

OSM is a map that anyone can edit. Next time you have an issue with the way someone else has mapped your local area, I'd suggest trying to fix it yourself first (it's easy, no hassle). And your criticisms may be right, but it wouldn't hurt to be more constructive and positive in your critique—we're all trying to improve the map here.

As a side note, Google Maps has copyright license restrictions that make it unsuitable to use as a source for mapping things on OpenStreetMap. I know you haven't started mapping yet, but I thought I'd mention that in case you were interested in doing more improvements to your local area.

Best,

Clay

Hi tguen,

What was the purpose behind changing all these nodes to railway=tram_crossing and railway=tram_level_crossing? Are these tags used anywhere else? They don't render nor seem to be recognized by any software.

Hi greenorangeparrot,

Looks like you changed the public_transport=stop_position nodes at the Charlottesville Amtrak station to public_transport=platform. Was this intentional? I'm going to go ahead and revert those nodes, though let me know if there was a reason behind that.

-Clay

Could you please specify what that reason is, and what project you are using OSM for?

Hi Danmuoki,

Looks like you accidentally changed the entire city of Nairobi into a building. I went ahead and reverted that for you.

Best,

Clay

Google Maps is not an acceptable source for OpenStreetMap data. While it may be easily available for free, its copyright license is unfortunately incompatible with OpenStreetMap. You may not use data copied or derived from Google Maps or Google Street View in OpenStreetMap.

Have you been using Google data as a source for mapping? If so, to what extent?
