Last week we published the latest version of Maps.Me. It's got the major version number increase — 8.0. And not for nothing: there is a brand new "Discovery" button, which shows interesting places around you. There are christmas markets on the map — not from OSM though. You can register as a "local guide", meet new people and show them around your city. Hotels from booking.com can be filtered by price, rating and availability.
But that is not why the release is worth celebrating. The main thing is, we've made a metro routing!
It won't be an exaggeration to say that this is the first even public transport routing application that uses solely OpenStreetMap data. Anybody can employ GTFS data, but using OSM is not that easy. All these relations — "route", "route_master", "stop_area", with enourmous tables in the wiki detailing their usage. Utter mess in the data, a result of mapping for a renderer. Very few people understand public transport mapping, so how did we even use it?
We started with a simple task: visualization and route planning for every subway and light rail network in the world. There are only 180 of these: 700 lines (which require at least 2100 relations, as you might know), 11700 stations. To map all of these, you have to get your tagging straight. And that's how the "Metro Mapping" proposal was made. Then I wrote the subway preprocessor, which takes a filtered planet file and produces an easy to use structure for every network, and a validation page, so you know what to fix.
And then me and a few other mappers started improving public transport relations in many cities, mainly in Europe. When we started, there were, like, three good metro networks. Just before the MAPS.ME release, there were 78 in 74 cities. I'd like to thank Claudius Henrichs for improving many routes in Asia: he's the first person outside our company that used the subway validator to improve public transport mapping.
What's for the future? The second proposal about rapid transit mapping is being discussed right now, and in mid-January the voting will start. Please read the proposal and if in doubt about anything, write your questions on the discussion page.
180 networks is not too much, but we need your help. Not a city in the United States has subway routing in MAPS.ME. Zero cities in China. If you live in Asia or any of the Americas and want to have subway routing on your next trip, please read the Metro Mapping tutorial, consult the validation page for your country and fix the tagging in OpenStreetMap.
We'd like to see public transport from OSM being used properly, not only in rendering of lines. If you work on an application, please consider using Subway Preprocessor to provide rapid transit navigation for your users. We in MAPS.ME strive for OSM to be used in as many ways as possible, and we continue to work on making public transport from OSM available to everyone.
A few days ago I forgot to spend a minute in an OSM editor. I had almost a month of consecutive edits, level 3 in OSM Streak with almost a hundred points. And then, after a hard day, I forgot about even opening a laptop. Neither an email, nor a telegram notification helped.
The next day I submitted my first changeset in a row. How much did I lose in the game? I had been receiving five points for each changeset (I was too lazy to complete tasks), now I get three, completing the tasks. The fourth level was two months ahead, now... I don't know, two and a half? 500 points is a long way to go.
I am practicing for mapping every day in the next year. Now I have seen how the streak could be broken, and to prevent that, I must not push mapping towards the end of a day, but do it the minute I see a notifidaction. Sometimes the task intimidates me: instead of opening the iD editor on a random place and mapping a building (which takes a minute), it requires opening JOSM, finding a specific place, looking at third-party services like Mapillary, remembering some piece of tagging, adding an imagery layer and uploading changes. All of this fits in five minutes, but there are days when I cannot spare that for OSM.
Hi, I am Ilya and I have been uploading changesets 15 days in a row. Not because I'm so into it or somebody makes me: I've made a tool that reminds me to do it. In a year I expect my HDYC activity chart to be completely filled. And you can have the same too.
Introducing OSM Streak: a website that gives you points for submitting changesets each day. You get 1 point for the first changeset, and then you get more: for example, I will receive 4 points for my next changeset tomorrow. And that is not all: it gives you a random task each day, so you don't stare at the map trying to come up with an idea. For completing a task, you get an extra point. And when you map many days in a row, you gain levels, which open more tasks.
Forgetting to visit a website is expectable, so OSM Streak is also a Telegram bot (find the link on the "Connect" page). With the bot, you can forget about the website: it accepts changesets and sends you tasks every day. Alternatively, you can subscribe to e-mail notifications, which will be sent on 1:00 UTC.
All the tasks and the website and the bot can (and should!) be translated into your language. We have English and Russian, and I would be very grateful for more translations.
Finally, there are 26 tasks at the moment, and you can add more by making a pull request or an issue on github. You can also use the source code as an example for writing a telegram bot, doing migrations with peewee ORM, sending e-mails with python or adding i18n with transifex.
Hi. I'd like to ask you to the Metro Mapping proposal page, read it in full and leave your vote below. The proposal mostly summarises subway and light rail mapping practices and introduces a few useful changes, listed in "What This Affects" section.
You will find many opposing votes there. You might be tempted to read only these comments and skip studying the material. It is simpler, and some of the authors are well-known in the community: they must know what they are talking about, right? And there are 8 screens of text, who would read that?
That is what I don't like in the current proposal system. It does not matter what the proposal actually contains, how deep an author knows the topic or if the features in questions are already mapped in a suggested way. What a great power you have when the voting starts — strike out weeks of work by writing a few words! You must be a fool not to excercise that power. And who knows what might happen if the proposal is approved? Everybody understands you cannot edit a wiki page after that. You would need to write your own proposal, and it might be rejected, so it is safer to just oppose.
For the first time in OpenStreetMap history I started actually using the data to route users through subways. And found out the tagging is insufficient: there was no sane way to map interchanges, and you could put thousands of members into some relations. For a mapper things also looked bleak: to map a subway properly, you would have to know how underground tracks go, and where underground platforms are located. No wonder that a beta version of a validator showed that the world had like three subway systems mapped good enough, out of nearly two hundred.
So I've put up this proposal page, that makes mapping subways simpler, and makes using the data easier. You could learn some things from it you've never thought about, like types of interchanges or the importance of colours. Then I wrote about the proposal to tagging@ and talk@ mailing lists, and in the course of a month got many great comments, that helped polish most sections, and rewrite some from scratch, adding more pictures and replacing blocks of texts with simple lists.
I have also finished my subway validator, that not only validates, but prepares data structures for metro routing and rendering. With it, I have been tidying up subways all over the world, finding a few flaws in the proposals, but mostly learning about regional specifics. I've done Moscow, London, Paris, Berlin (both U-Bahn and S-Bahn), Yokohama, Algiers, Lima, Pyongyang and dozens more cities. Their subways conform to the proposal, and I have not broken any external app that used these, or uploaded any extra tag. Well, except network:metro in Germany, since they have an interesting way of tagging networks (thanks Nakaner for the explanations).
With over 60 metro networks mapped, dozens of questions answered, most of which affected the proposal, after discussions in wiki, talk@, tagging@ and in changesets, I decided that the proposal is ready and started the voting. For a moment I thought the OSM community was reasonable. It's like in my seven years I haven't learned anything. Not after the turn lanes proposal, not after hate messages about the water=* proposal, five years after it's approved, not after stalled pull requests to the OSM website.
Very few people in OSM are willing to compromise. Especially people from Western Europe, who think they own the project. Because you cannot edit a wiki page without a proposal, I assume. Because no matter how many suggestions you've accepted, layer=-3 instead of -2 makes the whole work moot. It would ruin the PTv2 schema. Because despite "discussions on the Talk page" policy, when the voting starts, you can write a page of opposing arguments right into the proposal page, and nobody would turn to the Talk page to read answers, not even the person who wrote the arguments. Because it is easier to oppose than to approve: all arguments are already laid out for you, and finding answers to these in a 56-kilobyte Talk page is too hard. For one person, it's because I should have discussed the proposal in his 3-messages-a-month mailing list, not in talk@ and tagging@.
You don't even have to understand PTv2 schema to vote for its extension. Like people who +1'd the Carto'Cité comment about stations as nodes and did not even click on the Metros link to see that OSM wiki had already told everyone to map stations just as nodes. OSM is told to be a do-ocracy, but work does not matter anywhere here. You might have studied prior art and mapped hundreds of networks, but Carto'Cité has an authority over french mappers, so you bet all of them will come and vote against your proposal, even understanding that their arguments have nothing to do with the proposal and are inspired by a potential breakage of some of their inner closed-source tools. By the way, we've talked that over, I've converted the whole Paris subway network to the new way, and nothing broke.
The voting closes in a week, and there are more opposing votes than approving. Of course it would not matter after I have finished my work on tidying up metro systems: the changes will just go into wiki with the "not approved, but widely used" status, like highway=milestone. To help novices understand mapping subways, some of us will direct them to this possibly failed proposal, because the wiki has — and will have — nothing better. The only outcome of failing the proposal will be my continuing frustration of interacting with the OSM community.
So please, if you care about our data not only conforming to some proposals accepted 6 years ago without practical usage, but also being relatively easy to use, please go to the Metro Mapping proposal page and leave your approval. I assure you the OSM database won't go down in flames after that. Thanks.
We all used building:levels and alt_name without giving it a second thought. Why are these keys built that way? Why not levels:building? To me, it looks like there is a rule for building composite keys.
ref is the basic tag for storing a reference number. For a reference number in some third-party table, we add a suffix: ref:third_party. That is because the new tag still contains a reference number. We have all such numbers in ref* keys. The rule of thumb is, the meaning of a value is defined by the basic tag before the suffix. ref:third_party is still a ref, and source:maxspeed is a source.
Sometimes we cannot use suffixes for historical reason. That is the case with name: we use name:en and other suffixes for names in other languages. For that reason, we build composite keys by prepending a content with an underscore: local_name or place_name. These are still names — a reversed order from the semicolon notation.
Of course, an underscore is also used for multi-word keys: public_transport and admin_level.
Then, there are namespaces. The most known is addr: with addr:housenumber and so on. Without a suffix, addr key has no meaning. The same with contact: and turn:. Namespaces are used for marking a group of tags that have the same meaning, have similar value formats and they are usually described on a single wiki page.
Some namespaces are used for tying properties to a part of the object described by the main tag, and for adding more specific properties of it. For example, building:* tags describe attributes of a building, and we also have roof:type and fire_hydrant:type. These words are most often put on the same object as a key or a value, e.g. building=yes or amenity=fire_hydrant, but also can mean a part of a structure denoted by these tags, like how buildings almost always have a roof.
The definition for namespaces is very vague, and some people mistake basic tags for namespaces. For example, we have 2.6k addr tags in the database. Sometimes people try to impose an prefix on a set of established and well-used tags to group these: it improves sorting in editors and allows for introducing many more similarly-named keys without "polluting" the namespace-less set of tags. That is what happend with "contact:" prefix: it is rare to see imports using "phone" and "website" tags without it.
Suffix or a namespace?
Telling a basic tag with a suffix from a namespace of the second type is harder. For example, what would be correct, building:height or height:building? roof:height or height:roof? This depends on four things:
- Which of the basic tags for each of parts is used more often, hence is expected to come first? In this case, building is used 28 times more that height. roof key is virtually unused.
- Which of these parts is more commonly used as a namespace? height: is used as a namespace for only three popular (more than a hundred usages) keys, none of which is globally spread. For building:, the number of prefixed keys with more than a hundred usages is around 120, for roof: — around 30.
- When removing the suffix, will the value be meaningful for the basic tag? It definitely won't be for building=100 m and roof=100 m, but will be for height=100 m.
- Will the basic tag without a suffix have the same meaning for the kind of objects with other similarly namespaced keys? In case of buildings, height would be enough without a suffix, and these tags are pretty widespread. But roofs are parts of buildings, so you would have either a suffix or a namespace.
So, for building height you would use a plain height key because of the fourth point. But for roof height, you would choose roof:height because roof: is commonly used as a prefix, as per the second point, unlike height:.
A case against brand:wikipedia
The reason for this post is the recent import of thousands of brand:wikipedia and brand:wikidata tags. I argue that the better choice would be wikipedia:brand and wikidata:brand, for the same reason as source:maxspeed and ref:whatever.
I accept the introduction of separate tags for an object and its brand: we can have two links for the McDonalds brand and a single notable restaurant under that brand. That covers the item 4 in the above list, and item 2 is not applicable, since both wikipedia and brand keys have not been used for namespaces. But points 1 and 3 are in favour of wikipedia:brand: the value is still a wikipedia article, and it is processed similarly to the value of wikipedia tag. And we have four times more wikipedia keys than brand keys.
To conclude, I suggest we do a mass-retagging of these imported or automatically processed keys before this mistake creeps into the wiki. Either wikipedia:brand or brand_wikipedia would be better options.
In some cases we failed to notice composite keys in proposals that are built contrary to the norm described here. Now you have to do some non-obvious tagging, which requires looking for the correct keys in the wiki:
- bridge:name instead of bridge_name (like old_name)
- source:ref, though the correct key source_ref is used 10 times more often. Note that ref:source would not be entirely correct, since you should be more specific in the suffix. source=tmnt with ref:tmnt=1 would be the correct choice, better than source_ref=1.
- This whole section on *:wikipedia prompted by this edit. Thankfully, we have only 20k of these keys, including the imported brand:wikipedia, so there is still time to fix this.
Did you know that the community voting for the OpenStreetMap Awards is open right now? We have chosen many nominees that did a great job last year, 45 of them! Not as many as the total number of active community members, but still a lot. And nine will receive the award at the Stat of the Map in August.
All nominees will be features in the series of OSM Blog posts: https://blog.openstreetmap.org/tag/awards2017/
Help translate the website and project descriptions to your language: https://www.transifex.com/openstreetmap/osm-awards/dashboard/
The voting closes on 16th of August. Vote now — you can change your choice at any time. Nominees would be glad to hear they are supported by hundreds of voters, so we would need at least a thousand people to vote.
Promote the Awards in your local communities, and if you are nominated, do encourage your subscribers to vote for you :) That is okay, provided you don't pay for votes or anything like that.
I have talked publicly about improvements to walking papers since at least SotM 2013. Made a blog post here in 2014 with some thoughts. But all I've seen were new ways to print tiles or atlases. While I admire the Field Papers and MapOSMatic fork improvements over the past years, a good walking paper is more than that.
For a long time I have been using a 28-step process to prepare walking papers for my mapping parties. It involved using Maperitive, Inkscape and some proprietary software. This year I finally got fed up with reanimating that old renderer, which doesn't work perfectly on Linux, and tried something else. I had always been recommending QGIS for printing maps, and I decided to try it myself. Turned out, making walking papers with it is really simple and straightforward, albeit not without issues.
I started writing another guide with QGIS and GDAL and all the new tech, but it quickly grew to 22 steps. Still too many. Having discovered the Python Console in QGIS, I started experimenting with automating a few tasks. One thing after another, and now I have automated almost everything, fixing a few issues in QGIS on the way. I present to you...
Walking Papers QGIS Plugin
It is the simplest way to prepare good walking papers for your mapping party. All you have to do is sketch the pie, and the plugin does the rest. Here are the complete instructions:
- Install the "Walking Papers" plugin from the official QGIS repository.
- Click the button with blue rectangles and choose "Download OSM Data".
- On a layer it created draw a polygon around your mapping party area (click a pencil button, and then "area" something near it. Left mouse button adds a node, right button closes the area), and choose the same menu item again.
- Yay, we've got a map. Sketch the pie with lines in the "Pie Overview" layer.
- Having finalized the pie, activate the "Pie Sheets" layer and draw areas around quarters that go on each of the printed sheets. Usually it's 2-3 sheets per a pie piece. Name areas like "4-west", where 4 is a pie piece number, and "west" helps a mapper to locate themselves.
- Click the blue rectangles button and choose "Prepare Atlas". That's all, check out the sheets and print them or export them to a PDF file.
Amazing, right? For a regular mapping party this way of preparing walking papers gives you much more control, and you would need to do much less explaining when handing these sheets to participants. Here is why I prefer it to atlas-printing websites:
- The data is very recent. It is downloaded from Overpass API, and you don't have to wait for a server somewhere to catch up. Buildings missing? Ask mappers to help drawing them, and print the papers an hour before the party, with everything they managed to draw by that time.
- Custom map style. With online services you have basically one good choice: Stamen's Toner. It is not perfect for walking papers: labels are in English, lines are too thick and dark, buildings don't have numbers and are hatched, so you can't draw anything on top of them, and the water is awfully black.
- Vector maps. You are not limited by zoom levels, and thickness is specified in millimeters, not pixels on some maximum zoom level.
- Custom attributes. The bundled style prints house numbers and building heights on buildings. It is not easy to alter that at the moment, but by manually editing
wp_style.yamlfiles in the plugin directory (
$HOME/.qgis2/python/plugins/walking_papers) you can add any attributes and change the style however you want.
- Rotation. It is frustrating when the roads in your mapping area go in 45° angle on the map, which makes most of the space on walking papers sheets unusable. With this plugin, maps on your sheets are rotated so objects on the map are as big as possible, and you have plenty of space to put down POI names and house details.
- Speed. No more waiting for an hour while your task crawls through the queue. Click a button, get an atlas, that's all.
- Works offline. Download a map area in JOSM beforehand, or copy it with a flash drive from a connected computer, and use the "Open OSM Data" menu item.
I hope this plugin helps you with organizing a mapping party. We know these don't help with attracting new contributors, but parties are fun, you get to know your city or village better, and the amount of data you collect is unmatchable by any other data collection method.
The OSMF Board elections happened a month ago, but only now I've got my hands on the anonymized ballots. Which means we are getting some statistics.
First, let's look at numbers. By the 10th of November we had 457 members eligible to vote. That is much lower than the previous year, when we had around 500 eligible members. Still, that's just a tiny fraction of active OpenStreetMap editors, so the room for improvement is huge. Other numbers have also dropped: 4 candidates instead of 11 in 2015, and 253 voters (55%) instead of 272 (~53%).
It was definitely the fastest and simplest of OSMF elections: with only four candidates, two of whom were running for re-election and other two much less known in the community, 77% of first choices were either Frederik or Kate. That is, Kate got three times as many first votes than the runner-up. I doubt there is a system in which the outcome of the voting would be different.
Let's look for the third place. Guillaume got 27 first votes and Darafei got 29. But did Darafei take the third place? By now you should know the STV does not make the answer obvious: it depends on how many people have listed these two as their second choices. And we see that twice as many Frederik's voters had chosen Guillaume for their second vote: 38, and 19 for Darafei. Kate's voters, on the contrary, preferred Darafei: he got 23 vs 18 for Guillaume.
Since the weight of Frederik's extra votes was much higher (0.4 vs 0.3) and more people gave the second vote for Guillaume, he gained most after the two transferral rounds: 60.2 vs Darafei's 55.4. Which would make him the third winner, had we another seat to fill.
Five ballots with just one candidate listed had either Frederik's or Kate's names on them. One ballot was empty, and 184 (73%) had all four candidates. Just one ballot did not have Frederik or Kate listed. 17 ballots had Frederik and Kate for third and fourth choices.
Darafei would take the third place in “Approval Voting”: if we count all mentions of candidates, regardless of a position, then Frederik and Kate would get 234 votes each, Darafei gets 217 and Guillaume 207. Incidentally, Darafei gets the most “disapproval” votes, that is, he is listed fourth on 67 ballots out of 184 that have all four candidates. Frederik has the fourth line only on 29 ballots.
Here is the original ballot file, which you can feed to OpenSTV to check on numbers, or analyze to get more statistics.
The OSMF Board did not change this year, which means we don't have to learn new names, but also that we won't hear new voices. I really hope next time there will be a lot more candidates, especially from under-represented countries. You don't have to be fluent in English or know accounting to serve on the Board. An urge to make OpenStreetMap better and an understanding that you would need to move in small steps is all it takes. Do push yourself for the elections this Autumn, and thanks for choosing us, the current Board members.
The editor usage stats wiki page has two useful tables for comparing editors: by number of users and by number of edits. And while MAPS.ME reach is clearly visible in the first one (alas, it hasn't still surpassed iD in users), the second table has much lower numbers for the mobile editor. Which is reasonable: MAPS.ME does not allow editing geometry, thus a single user can make more edits in a day, than all MAPS.ME users in a month.
I was wondering if we could compare only the type of edits our mobile editor allows, that is, POI edits. And with daily replication diffs, I did:
This chart shows that while users of iD and JOSM editor create more points of interest than MAPS.ME users, it's not by a large margin.
I noticed days when 10k or 20k new POIs were uploaded with JOSM, and wondered if the picture would change if we took median values for days of each month. That is, from a sorted array of numbers we would take the middle number. Turns out, not much.
Most of us know how hard it is to update POI data, besides fixing geometry or fixing tags. Not only you have to go out and collect new opening hours or names, but also you must know that something has changed. Mobile editors usually excel at that, so why editing numbers are higher for desktop editors? That's because I could not separate meaningful tag edits from automated, or geometry changes from tag edits. Maybe if I could, MAPS.ME's share of POI edits would be much higher.
Last time it went pretty well, so let's try another long-standing issue. Namely, #1274.
You can register or log in to the OpenStreetMap website using a social account: Facebook, GitHub, Google. The thing is, most of us have many social accounts, but you can only link one to your OSM profile. If you click a wrong button, you will have to either go back or register a new account. You cannot log in to your account using different social buttons.
For me, that is a problem. I would like to not remember which of the buttons I clicked when I tested the social login, and which of these is linked to my main OSM account. For that I would like a social accounts management in the settings page. Alas, I don't have time and skills to add that, but I have a hope that somebody has. And for that I'm willing to pay a small grant: a hundred euro, like the last time.
The offer stands for two months: the pull request to openstreetmap-website should be submitted until 15th of January and merged until 15th of February. Right after merging I will transfer 100 € to any given credit card or bank account.
I've just counted some statistics on a planet file from 14th of October. Here it is:
This table shows a number of nodes, both tagged and untagged, that are referenced by ways and relations. You can see that nearly 97% of 3.5 billion nodes are untagged, and most of these — 88% — are part of exactly one way or relation. Like, when you trace a building, you add four untagged nodes that are part of that closed way.
98.4% of all nodes are part of something, but only 12% (424 million) have two or more parent objects. This could help with designing a data storage for nodes.
There are equal amount of tagged nodes that are not part of anything, and part of an element. Interesting are these 9 million tagged nodes that are part of two or more ways. The taginfo says there are 2.5 million crossings and 860 thousand traffic signals, so that's a ⅓ of that.
Finally, we have a million of nodes with no tags not being a part of anything. I wonder when someone puts on their OSM saviour cape and a programmer's hat and rids us of these.
Many mappers agree that simple and accessible editors are hazardous: the simpler editor is, the easier it is for a horde of newbies to submit wrong data. This was a main argument against Potlatch, and then iD. Now MAPS.ME built-in editor allows for changing tags and adding nodes with just a few clicks for any of our tens of millions of users. Which of course has led to a number of questionable edits.
The first field in any place card is name. When we released the editor in April, it was a single field for editing the "name" tag. You changed a name — the new tag value was uploaded to the map.
Complaints started coming almost immediately. Turns out, some tourists were renaming attractions to their language for easier navigation. If you look at the Questionable Edits wiki page at the time, you'll see that names in wrong languages are the most worrying kind of edits.
How do we fix that? Well, finding the language of the name from its characters could work for some languages (like Chinese vs. English), but not for most. Adding a warning that users should type only what's written on a plate is better, but it was there from the start, and nobody reads instructions. Removing the field completely, like some suggested (along with the rest of the editor) could solve the issue, at expense of the better map.
In August, we prepared a list of native languages for each country. For example, in Finland it's "fi" and "sv", in Estonia it's a single "et". India has 11 languages, though its regions have less. We took this from the Wikidata, which may be incomplete and sometimes wrong. If you have a minute, check this list for errors. Languages should be ordered from most-used to least-used.
And with that, we completely disabled editing of the "name" tag in the 6.3 release. Mappers were asking, and we delivered. Now users were presented with one or two native language name fields, plus an English name and a name in a user's language. For example, if you are a russian in Helsinki, you'd see editors for "name:fi", "name:sv", "name:en" and "name:ru". This way it was less likely Chinese names would be entered into e.g. name:en. And since the default style on osm.org uses only the default name, changes from maps.me wouldn't be shown there.
Except for new objects: when a user creates a POI and fills any of the native language fields, that name gets copied into the "name" tag. But not when editing. Which started causing another kind of error: when a shop had changed its name, we would get old name in the "name" tag and a new name in "name:lng". It displays properly in maps.me, since we favour localized names, but not on other maps. And some mappers started complaining about equal values for "name" and "name:lng".
With the 6.4 release, we adjusted the workflow again. Keep in mind that our goal is to prevent accidental mistakes by users, not by experienced mappers who know how the application works. For the latter, we added a special language: "Native for each country" at the very bottom of the languages list. That's right: it is a way to edit the "name" tag directly.
When creating a POI and filling a name in a local language, that name will be not copied, but moved into the "name" tag, so you won't see duplicated values in tags. In my opinion, that's a drawback, but still, that's what mappers requested.
Now the complicated part: when there is only one local language for a region, like in Estonia or US, a user has a chance to change the default name. First, all empty name fields for local languages and English are pre-filled from the "name" tag. If a user have edited names in both languages, this would mean the user knows what they are doing, and the app will put the local/English/any other (whichever is not empty) name into the "name" tag.
This still means you will get discrepancies between "name" and "name:lng" values for countries with more than one local language, or with users who don't have time to edit all the fields. Know how to make name editing more safe and effective? Please share it here in the comments: maybe we could make it more transparent or even more smarter.
Okay, I've got tired of this UI, and I'm swamped with other tasks, but there is some money left from my travel to SotM. So I am announcing a grant: 100€ for a merged pull request allowing people to subscribe to comments in OSM user diaries. (NB: 300€ now, thanks to Stereo and Mikel.)
There should be a checked by default checkbox near the "Save" button ("Receive notifications about further comments"), and a button to subscribe/unsubscribe. All notifications should go to e-mail, much like changeset comments now.
When you have your pull request merged, I'll transfer that money to your card or bank account. And of course I'll publish a big thank you :)
The offer is not indefinite: the PR must be submitted until the 1st of November and merged before the 1st of December. And yes, there might be a competition, in that case OWG will decide the winner by merging a pull request.
This Sunday, we will meet the nominees for the first OSM Award and learn who gained the most votes in each of the six categories, including Mapping and Blogging. 650 mappers have already voted, and if you have not, please head to the awards website and make your choices. All you need is an OpenStreetMap account.
The voting closes on the morning of September 22nd, when the Brussels Maptember begins with two great conferences: HOT Summit and FOSS4G.be. After that we will dive into OSM topics at the State of the Map, and on Sunday, before lightning talks and workshops, we will know the winners.
But for now, there are still ties in some categories, and your vote can decide who will get the award. Do vote now and meet us at the State of the Map!
Which popular editors do we have now? According to statistics, three of these: iD, JOSM and Potlatch 2. The next four editors are mobile: Go Map, OsmAnd, Vespucci and Pushpin each have a thousand of users. Today there is another one, which now has less than a hundred users, but aims to go for the first place: MAPS.ME.
As you might know, MAPS.ME is a popular app for using OpenStreetMap data on a phone or a tablet. It has geocoding, routing (using OSRM engine), bookmarks and 3d-buildings. It runs both on Android and iOS devices, and it is very fast. Obviously it works offline: you just have to download some countries. Besides speed, MAPS.ME is known for simplicity: even I can understand which buttons to press, without examining every control and menu item first.
Just now we have released the first major update this year. It has better geocoding (and reverse geocoding), smaller regions (no bigger than 70 MB, most are below 50) and, the most important change, now it can edit the map! In most POI cards (click on a POI and get one) there are two new options: «Edit place» and «Report a problem». The first one opens a simple (as in, easy to understand) editor for relevant fields: name, address, opening hours. The second one is for leaving OSM notes. Also there is an «Add a place» option on the menu. So yes, it's an editor.
We decided not to build proxy servers, but to connect each of our users directly to OpenStreetMap. Which means, there is a sign in / sign up option that pops up when you edit a feature. It uses OAuth, obviously, and for new users it promotes using Facebook / Google authorization. So, every MAPS.ME user that edits the map submits their confirmed e-mail, so you can contact them. It works, as I have contacted some of the users during the beta testing.
OpenStreetMap currently has 25-30 thousands of users editing monthly. MAPS.ME has more than 7 million monthly active users. So I assume that in time it would be the most popular way for adding and editing points of interest in OSM. You can monitor edits made with the application: that service will most likely break when there is more than 5 edits per minute, but for now it works. When you see a mistake, "Level0" button is the fastest way to fix it.
I've been using MAPS.ME editor for two months, and it is good. I have finally added and refined POIs around my house, and I add new objects each time I go somewhere. Because it is so easy, and because I use the application for navigating anyway. I have been saying since Autumn that mobile editing will be the next step of OpenStreetMap development, and now we can witness it in real time.
If (when) you encounter a bug, please write to firstname.lastname@example.org. The next release is planned for the end of the month, so with your help we can make the editor even better. We know some of drawbacks: incomplete type list, users can add the same feature multiple times, no notifications for sent changes, non-native facebook/google authorization. Most of issues will be fixed by the next version, but we would like to hear your opinions on how to make OSM better with this new editor.
Happy editing, and we're sorry you will have nothing to update around your house in a month :)

Did I mention to vote for me in the upcoming elections? :)
I am Ilya Zverev, a.k.a. Zverik, currently living in Russia. I've nominated myself to the OSMF Board, and now I have supposed to write a manifesto, touching on diversity, transparency and other serious topics. But the thing is, I've read all manifestos for past three years, and all of them (except Frederik's) are boring and didn't affect anything. So what if I show support for transparency — would it help? Nearly all candidates supported it, and look how verbose Board minutes are (they aren't).
Do you know what the Board is working on? I don't, and I read the minutes. There are two options: either the Board discusses a lot of things on their private mailing list, or they actually are working only on topics spotted in minutes. Both of these are not good: I am a member of OSMF, and I expect to know what's in store for OpenStreetMap. I hope it would change, and maybe I could help it — but after Frederik's revelations, I am not sure. I'll try.
I support diversity. The Russian community is severely under-represented in OpenStreetMap, despite being the fourth (occasionally the third) biggest in the project. Though I don't like needless «regionalizing» of some aspects, e.g. tagging. Obviously, we should promote OSM in more countries, though I don't see how it is the Board's task. Last year I learned what gender diversity actually means, how inequality is enforced by nearly every aspect of most cultures, and that IT has it worst. But also I was taught that, as a man, I can do nothing about it, other than properly teach my daughters. So I have nothing to offer on the topic of diversity.
What I am interested in, and what is one of the main Board's duties, is supporting the OSMF. I joined it in 2011, but never was sure what is the point of being there. Supporting the project monetarily — yes, but it is simpler with donations. The mailing list is sometimes entertaining, but mostly silent. I don't know who other russians in OSMF are, and cannot connect with them. I have no say in any of the decisions, except during the yearly AGM. Nothing in OSMF motivates me to do anything, though there is a lot of subtle shaming: you are not participating in any WG, you are not donating enough, you are not attracting more members to OSMF. Being an OSMF member is not fun, and I intend to change that.
And the money. Do you know what the last year WG grants were spent on? Only OWG seems to spend money on something useful. OSMF has a few pounds on its account, which doesn't seem to increase much, but also it doesn't spend it on anything outside the State of the Map and servers. There were a lot of promises and ideas in past years. I can remember the Ulf Award, software grants, mapping party funding. I doubt any of that was discussed by the Board: in my mind, it deferred these matters to working groups, and the groups weren't interested. I expect the Board to spend more, and to collect more. I'd like to have developer grants in the OSM, and not rely on big software companies to technically advance the project.
Corporate membership is the way to get more funds for the OSMF. Well, increasing the regular membership ten times, and that. My employer, MAPS.ME, is a corporate member, so I know how hard and frustrating it is to become one. This membership is not promoted in any way, which is one of the reasons we get only 4-5 companies every year. Maybe we should learn from Wikimedia: they are more visible and attract more big sponsors, and we could do with a couple.
I am not a good manager: I have no experience in talking with huge companies or managing teams (though I've organized quite a lot of mapping parties, and some conferences). But I won't be alone on the Board, and members there are good in different ways. I'd be glad if Mikel is elected, we need an experienced person like him. My expertise is in being an OSMer for a lot of years, in writing news and hoping OSMF would generate more of them, in being an OSMF member and not knowing why. I want to change that, to make OSMF more visible and meaningful, and that's why I want to be elected to the Board.
If you are not yet using MAPS.ME, you are missing out :) The most frequent complaint from the mappers was that official maps in that application get updated only once a month, along with new releases. I usually map stuff the day before I'm going out, so this update cycle does not suit me. And since I work for them now, I can fix this.
Since this month, there are daily updated map files for MAPS.ME. To install downloaded files on Android, find MapsWithMe directory on your device (you can check "Settings → Map storage" in the app), and put new files there. You should delete old maps and directories with same names (the latter is to clear caches). And probably restart the app. On iPhone and iPad, just use iTunes: find and open MAPS.ME application, delete old maps, upload new.
Maps are published every day at around 5am UTC. Mwm files are maps, routing files are needed for car routing (pedestrian routing doesn't need them). In a couple of days a new version would be released, and it will be required for daily maps to function.
These files are not official. The application may behave strangely (there will be notifications about outdated maps), data may be broken (it's OSM, it is always broken), and your application may crash. If you encounter anything strange, you can clean the MapsWithMe directory and/or move the app from SD to the device memory, which must fix most bugs. Daily maps are my initiative, and MAPS.ME company is in no way responsible for these. Of course, I'm ready to answer any questions.
Surely now is the moment for OpenStreetMap to accelerate adoption, usage and uptake? But why hasn’t this already happened? Why hasn’t the geospatial world run lovingly into OSM’s arms?
Gary Gale published an interesting article on removing SA clause from our license (actually, the major part was about business-friendly face, but you know the principle: want it? go do it). We've heard it before, from Mapbox. As Richard points out, that won't happen any time soon, because there is clearly less than 2/3 of active contributors supporting the idea.
And these opinions strike me as lacking an understanding of OpenStreetMap project. Are we mapping for PNDs? Yes. Are we mapping for commercial companies? Of course. Would we like a thousand more commercial users promoting OSM by simply using it? Yes, go ahead. What? They cannot do that right now?
Well, we can wait. That what distinguishes us from other map data providers: we can really wait. OpenStreetMap is slow, but unstoppable. Mapbox and other businesses have immediate tasks, and for that they need a fast reaction from OSM. But OSM isn't fast. The last license change took 3 years. That's just a bit less than Mapbox has existed. Some think that because we make maps for crisis areas so fast, we are very responsive – but we are not. And it is good.
What I like in OSM, is that it is not going anywhere. Businesses appear and go bankrupt or sold, new datasets are published and then forgotten, but nothing ever can happen with OpenStreetMap. The question is, what will happen if we wait 50 years? I can bet a hundred bucks I'll still be mapping my town in OSM when I'm retired, but will Mapbox, HERE, Google, Yandex, TomTom exist? If we are to act right now, what good will it do to our project in a scope of 50 years? On that scale, publishing a new tagging proposal seems more important that changing a license, just so that some more businesses and government organizations could use our data without having to change their ways. Tags will remain, organizations – not so sure.
And that's why I think a share-alike license is perfect for our project – at least until another popular mapping project appears with a more open license. If we are starting to look good for businesses, look ahead 50 years and think, why we should adapt to their needs, and not vice-versa.
Of course, we can start thinking about changing the license, but don't expect a reaction in the nearest 10 years. Not at least until we've updated our API.
