Validation talk at SOTM Milan: Can we validate every change on OSM? 25 days ago

Whilst it's great that changesets near and not so near are being reviewed, I wouldn't equate "Flagged for Review by Mapbox" with "vandalism", which your graphic above suggests. Even if they're problematical, most "flagged as vandalism" edits aren't (for example of the last 6 "vandalism" issues reported to the DWG via the "report" function at an absolute stretch only 3 could be considered "vandalism" - more common reasons are new users trying to get the hang of things, and disagreements over tagging.

My quest to map the fairgrounds. 25 days ago

Yes - "showground" is British English for what Americans would call "Fairgrounds". Local ones often less permanent - the nearest one to me is just a field with fancy gates 363 days of the year.

India is not Bharat about 1 month ago

The name of India was recently changed from English to Hindi and back - see and the rest of that thread for details. It's possible that you're seeing a tile with the "old" name in it from a cache somewhere (such as your browser cache).

Why does OSM default render highway=path as a cycleway? about 1 month ago

The isn't really the fault of OSM Carto - "path" in OSM is a pretty nasty concept. It's really just "a way of getting from A to B that isn't wide enough for 4 wheeled transport". However we are where we are, and its certainly not going away.

"bicycle=designated and foot=designated" just means that two forms of transport are suggested to use that route as opposed to others; it doesn't tell you anything about what sort of "highway" it is. Personally I'd always try and use a more appropriate highway tag if there is one (does it look like it's designed for use by bicycles? highway=cycleway, with appropriate access tags. Horses? highway=bridleway, again with appropriate access tags.

You can also use other tags (surface, width, tracktype, smoothness etc.) to try and get the sense across properly.

Share your story: Open Gender Monologues about 2 months ago

@b-jazz That comment in that SOTM-US video is clearly meant as and taken as a joke (clue: the audience laughs). I've no idea what you said to the SotM-US organisers or what they said to you, but perhaps you need to be a little more open to what other people think - sometimes things are a little more complicated than you might at first think.

Is it usually difficult to come to a local concensus on tagging? 2 months ago

Is it usually difficult to come to a local concensus on tagging?

The short answer is "yes". It can be particularly tricky when there are relatively few mappers in an area, and so less chance to see other people's views on how best to tag certain sorts of objects. Generally speaking the way to resolve these sorts of issues is to talk about them, but there has to be an amount of give and take - sometimes in OSM discussions there (and I'm thinking of this tagging list thread in particular here) there isn't.

There currently seems to be a bit of a discussion going on in the forum thread at the moment, but there aren't that many people there (and especially not many Canadians). The Canadian country forum is also very quiet. There's a bit more at the talk-ca mailing list; maybe try there?

On the tagging itself, the only other thing that I'd add would be to try and capture as much other information as possible to give renderers a chance of making a decent job of the road regardless of classification (surface, width, that sort of thing).

Here is a Free Republic of Liberland 3 months ago

But does it have a beer and an airline?

Will the DWG block us all one day? 3 months ago

First things first, obviously Betteridge's law of headlines applies here. :)

To be clear about one thing - the user blocks list is not a "list of shame". As described on the DWG's wiki page, blocks 'don't imply that users have done anything wrong, and often contain friendly language to try and communicate that fact. Usually before any block is applied (even a "0-hour message that has to be read") attempts will be made to contact the mapper, such as via changeset discussion comments'.

It's also meaningless to try and equate blocks (or OSM accounts) with actual human users. Where one user (or a group of users) has created multiple accounts to try and "make a particular edit" in spite of their being problems with it (real examples: change all the tracks in an area to roads so that their preferred Garmin map shows them; changing their school's name to something like "please don't give us any homework") then the number of blocks per user or even per OSM object might be very high; they don't mean that more OSM users are proportionately being blocked.

As Mikel is I think trying to suggest, it would be possible to obtain details of the actual incident from the block(s) associated with it (and "incident" will most often be "hello and welcome to OSM, some people are trying to help you"). Excluding data from deleted users, OSM changeset, object and block data is public, so any OSM user can do that (I'm assuming here that OSM's eventual GDPR implementation will somewhat resemble what Geofabrik and HDYC have already done).

Welcome to OpenStreetMap! 4 months ago

In a diary that's shared between people of many different cultures and languages, I wouldn't assume that anything was obvious, actually.

Required URL / graves / was not found on this server. 4 months ago just looks to be domain parked right now. I'd suggest contacting whoever you think created it.

CartoCSS IRC channel? 5 months ago

@Marcos Dione That sounds plausible, yes. Although it's a proprietary channel there's an "open sign-up" page somewhere, though obviously you'd want to archive anything you want to keep as obviously they can take it away at any stage in the future.

CartoCSS IRC channel? 5 months ago

I'd imagine that most OSM CartoCSS people who use IRC will either be in #osm or #osm-dev, so I'm not convinced that a new IRC channel would get that many people in it. No harm in trying to create a new channel of course and see who turns up.

Another possibility might be (but you'd need a well-defined question there not just "help!") or maybe the US-based Slack might have some US-based CartoCSS people in it.

Switch2osm "Manually building a tile server" page updated 5 months ago

Do you think at this point the whole instruction should be just "docker up wherever/openstreetmap"?

It rather depends on what you're trying to do, I think. If you're already familiar with Docker etc. and "just want to render some tiles", then quite possibly. If you're not, or you want to set up a server to serve custom tiles in an app, or you want to understand more about how everything hangs together, then probably not. The idea behind these guides is that you can follow them with essentially no existing knowledge. The carto docker guide just throws you at this page and expects you to figure out for yourself what you need.

Following the same steps for 4 years seems to be a bit redundant in 2018.

The "obvious bit missing" to me is an equivalent guide for some sort of vector mapping. OpenMapTiles is a whole lot nearer to that than it used to be, but it's not quite a solution to the same problem.

Issues with Japan imports 6 months ago

(re tag removal) JOSM, and some other editors, will remove some imported or previously set tags that subsequent discussions have suggested are best removed. See the comments at for example.

How to track and encourage contribution? 6 months ago

I am very surprised that you consider it to be "fairly straightforward" (!!!) to get hundreds of command-line steps working. I mean, I've done a fair bit of Linux development, and I'd schedule several days to get something like that working; for the general mapper, that's clearly a non-starter.

The entire text of the page is only 402 lines long, and most of that is description. Based on my experience if you've done it before I'd estimate it would take about 2-3 hours to cut and paste the commands onto a server and complete the data load (if for a relatively small region) - including the documented tea breaks!

How, exactly, does having ones own map server help with that?

In at least two specific ways:

  1. If there's a group of people working on a lightly mapped area (perhaps a HOT or similar project) then a server that's under their control is capable of rendering whatever tiles they want, at whatever zoom level, whenever they want. This is not currently possible with the tile layers on for all sorts of reasons, including the "long tail" of applications fighting for those same free tiles.
  2. You're not limited to the tile styles currently displayed on the OSM website. OSM's standard style is a compromise designed to cover vast deserts and tightly-packed cities. It's limited to a relatively conservative maximum zoom level which prevents a lot of detail being visible but suppresses what might be important features in some places (paths and tracks, say) when zoomed out.

You say above that the situation is "sad", and I'm trying to help provide a solution. There's always room for improvement of course - an opportunity for someone to create a better mousetrap - but to say "All the ways that used to exist, to get visual or numerical feedback or progress metrics, are gone" isn't remotely true.

How to track and encourage contribution? 6 months ago

Re "Refreshing the map after doing major edits", I wouldn't currently rely on any of the maps available at for this, for the reasons that you describe. For a number of people working in a relatively lightly-mapped area it'd be fairly straightforward to set up a temporary rendering of just that area, and have the tiles as up to date as you like (since you're not fighting for resources with all OSM mappers worldwide). The switch2osm guide would be a good place to start for this, and most countries or regions could be happily rendered by a bit of spare time on an off-the-shelf desktop PC or equivalent.

How are you "supposed" to map landuse? 6 months ago

I also wouldn't assume that all comments on diary entries** are anything other than the contributor's personal view :)

With regard to trees / woodland / forest et al there's been a lot of discussion about the various tags in use and what they "actually mean". This page describes 6 approaches. For trees, the main tags used are landuse=forest with 3 million examples and natural=wood with 4.5 million. By contrast, landcover=trees has 19,000. If it expresses what you want to get across by all means use it as a tag but do be aware that many data consumers will be confused by it.

More generally, I wouldn't worry too much about landuse (at all), especially not about "covering the entire globe". It's far more useful to know that roads and paths are present and correct, and that shops and offices (that people actually visit) are up to date.

Surau and parking in building enhancement suggestion 6 months ago

@AkuAnakTimur What gets rendered on OSM maps (including the 4 that are available on doesn't depend what's in the wiki (proposals etc.). It's mostly to do with the tag having a clear meaning and being widely used across the world (see the discussions about new tags at e.g. the standard style's github issues list for more detail).

Of course, if you want to create your own maps that show this tag with a particular icon, you can.

When the World Needs a Map, Give them a Database 6 months ago

Silly question, but what does "STOM" stand for here? This suggests various possibilities, the only vaguely "geo" one of which is "safe transport of munitions" which seems unlikely...
