The “Birthday” of OpenStreetMap is lost in the sands of time. Observance of the anniversary of the creation of OpenStreetMap is held on or about the 9th of August, which is the anniversary of the registration of the domain name. The concept of OpenStreetMap predates the domain name registration, but that seems a suitable anniversary date.

This year the anniversary will be celebrated on
10th of August!

Will you organise an OSM birthday party?

How to organise a community birthday party

  • Contact OSMers in your area and talk among yourselves. Decide what you want to do.
  • It can be as big or as small as you want. A few people meeting for some food/drink, or a bigger event.
  • Invite new people! It can be a great way to spread the word about OSM. Promote your event.
  • You can make/order a birthday cake. See previous examples of OSM cakes for inspiration. Don’t forget the attribution!
  • If you take photos, you can share them on the OSM wiki afterwards.
  • Edit this wiki page and put details of your event in.
  • Remember a core principle of OSM: Have fun!

If wiki editing isn’t your thing, email with your event details and we’ll add it ūüôā

Events are already planned in Japan, Belarus, Germany and the US.

OpenStreetMap was founded in 2004 and is a international project to create a free map of the world. To do so, we, thousands of volunteers, collect data about roads, railways, rivers, forests, buildings and a lot more worldwide. Our map data can be downloaded for free by everyone and used for any purpose ‚Äď including commercial usage. It is possible to produce your own maps which highlight certain features, to calculate routes etc. OpenStreetMap is increasingly used when one needs maps which can be very quickly, or easily, updated.

1 million map contributors!

We passed a milestone recently which deserves some celebration: OpenStreetMap has now reached 1 million map contributors. Over the lifetime of our project, 1,000,000 different users have created a user account and made edits to the map! 1 million is a big number, and the growth of our community continues apace.

“At its core, OpenStreetMap is all about humans sharing knowledge about the places they visit, live and work in. Our fantastic project is only possible thanks to over a million individuals who generously volunteer their time to help others find their way in the world.”
Peter Barth – OSMF board

If you haven’t tried contributing to OpenStreetMap yet, it’s not too late to join a million others! sign up today and map your neighbourhood!

You may remember we celebrated 1 million users way back in 2013, but that was the count of signed up users — an impressive number, but not everyone who signed up has yet contributed to the map¬†(Why have users signed up but not contributed? The reasons for this have been described in various ways over the years but similar participation patterns are seen in many online communities)

Simon Poole has been crunching the changeset logs and watching the count of map contributors tick past 1 million:


Read Simon’s diary entry for more analysis including a look at recent editor software usage trends. Of course we are tracking many other stats on our ‘stats’ page too.

So let’s celebrate! One million and still growing!

Happy New Year!

2017 has been a good year for OpenStreetMap and the OpenStreetMap foundation. Many things happened and have been achieved that push our project even further. As not everyone was able to watch out for all that great news, we’ll highlight some of 2017’s events and give you some pointers for a further read.

Kate Chapman rounded off the year with her chairperson’s report in which she highlighted the growth of the Foundation membership, enabling it to further support our project. We have almost 900 foundation members in December 2017, which is in part a success of our membership drive last year. In addition to our individual members, we have an additional 24 corporate members, thanks to our new corporate membership program which took effect on Jan 1, 2017. Besides many renewals and tier upgrades we were able to welcome two new bronze members and five new gold members, with many big players on the list. Corporate memberships are a great way for some of our biggest data users to help remove the financial burden from our mappers who already donate so much of their valued time. A larger number of corporate members also makes us less dependent on single large donors. This is a great success.

Let us not forget that it’s the mappers who ultimately power our great geographical data though, and as foundation membership has grown, so has the number of mappers. In the final weeks of 2017 we hit the milestone of 1 million map contributors! We’ll bring you some more details of what that means in another blog post. One big boost to our contributor numbers that received much public attention was Pok√©mon Go. The news coverage about this game making use of OpenStreetMap data encouraged many players to go edit OpenStreetMap. Back then, we even published a blog post with tips to help new mappers coming from Pok√©mon Go. While the Foundation and its Data Working Group received some complaints about bad edits related to the game, many more trainers made valuable changes to the map. And in the end, players with constructive, fact-based edits persisted and continue to enrich our project.

OpenStreetMap is a large project with a worldwide community and as such, we’re quite diverse. That’s also why the OpenStreetMap Foundation is pushing for more Local Chapters (LCs) to form local representations of OpenStreetMap enthusiasts. That being said, we’ve been able to welcome three(!) new Local Chapters last year already. OSM UK, was last year’s first new addition (welcome!), followed by OpenStreetMap France (welcome!). Technically there has been a third one early in December 2017! But hold your horses. We’ll be bringing an announcement of that one very soon! That means the OSMF has six Local Chapters as of now, and hopefully at least two more LCs will follow in 2018. By the way, if you’re from a local community and are interested in starting your own Local Chapter or just want to chat about it or seek input, we had some meetups at the last two SotM conferences with new ideas and have revived the local-chapters mailing list for that reason.

Speaking of SotM, the global annual conference of OpenStreetMap went to Japan this year. State Of The Map 2017 was another fantastic event, and our busy organizing committee (one of the foundation working groups which you can join!) is already ramping up to bring together the 2018 conference in Milan, Italy.

There have been many more topics and development over the year and Dorothea, responding to feedback on our foundation members’ mailing list, compiled a list of foundation tasks and projects that have been either completed during this year or are still ongoing. Furthermore, there’s also a great overview of hers that summarizes all OSMF board meeting minutes in 2017, featuring topics discussed and decisions taken.

Speaking of the OSMF board, we had board elections in December 2017 and want to take the chance to congratulate Heather Leson and Paul Norman for being voted to the board! This year’s elections have been somewhat exhausting with about 50 different threads and about 600 messages on the foundation members’ list, compared to not even half that many during the rest of the year. The language was a bit heated at times, although there were also quite a lot of interesting and valuable discussions. Let’s hope that some of this energy and passion will be channelled into year-round community involvement in foundation matters.

And so, with a great and eventful 2017 coming to an end, we’re welcoming 2018, looking forward to yet another great year for OpenStreetMap!

Mappy new year everyone!

  • Why: Because there will be a lot of mapping to talk about


Hack Weekend December 2013

Last December we had a hack weekend in London, thanks to AOL UK/MapQuest (my employer) for donating meeting space in their offices and food. About 20 people turned up and did some awesome stuff and we, at the Engineering Working Group, thought you might be interested in what went on and perhaps running your own event.
