Routing on OpenStreetMap.org

Good news for OpenStreetMap: the main website now has A-to-B routing (directions) built in to the homepage! This will be huge for the OSM project. Kudos to Richard Fairhurst and everyone who helped get this up and running.

You might be thinking, “Why would this be huge? Isn’t it just a feature that other map websites have had for years now?” Well, the first thing to note is that the philosophy of OpenStreetMap is not to offer a one-stop-shop on our main website, but to create truly open data to empower others to do great things with it. So there has already been fantastic OSM-based travel routing for many years, on excellent websites such as OSRM, Mapquest, Graphhopper, Cyclestreets, Komoot, cycle.travel… the list goes on and on.

But all of those things are on other websites and apps, so people don’t always realise that OpenStreetMap has this power. What this latest development has done is really neat: the OSM website offers directions which are actually provided by third-party systems, but they are included in the main site via some crafty JavaScript coding. So as well as being really handy in itself to have directions available, it helps “first glancers” to see all the things they can do with OSM.

But that’s not what makes it huge.

What makes it huge is the difference it will make to OpenStreetMap’s data by creating a virtuous feedback loop. One of the main reasons we show a “slippy map” on the OpenStreetMap homepage is because people can look at it, see a bridge that needs naming or a building to add, click “Edit” and fix it straight away. That feedback loop is what allowed OpenStreetMap to build up what is now the most complete map of many regions around the world.

But we have a saying: “what gets rendered, gets mapped” – meaning that often you don’t notice a bit of data that needs tweaking unless it actually shows up on the map image. Lots of things aren’t shown on our default rendering, so the feedback loop offers less incentive for people to get them correct. And that goes doubly for things that you never “see” on the map – subtle things like “no left turn” at a particular junction, or “busses only” access on a tiny bit of road, or tricky data issues like when a footpath doesn’t quite join a road that it should join on to. Now that people can see a recommended route directly on the OSM homepage, they have an incentive to quickly pop in and fix little issues like that. The end effect will be OSM’s data going up one more level in terms of its quality for routing. This will empower everyone to do great things with geographic data and getting from A to B.

So find yourself some directions today!

OpenStreetMap Local Chapters – Welcome Iceland

The OpenStreetMap community has a wide array of different local groups forming in different corners of the globe. It’s time to formalise the idea of “local chapters”. We now have a definition and a process, and we have our first official OpenStreetMap Foundation Local Chapter!

OpenStreetMap á Íslandi” is a subgroup of Hliðskjálf, an Icelandic society for open and free geographic information data. Well done to Jóhannes from Hliðskjálf who went through the process of getting this organisation set up as an OpenStreetMap Chapter.

Of course we have always had local OpenStreetMap groups forming all around the world, small groups of collaborating mappers, but also groups on a bigger country scale. These organisations help to present OpenStreetMap in a particular language, and engage a community with consideration for local culture and customs.

The idea of local chapters has long been discussed, as a name for these groups. We’re borrowing this idea from the Wikimedia foundation. And now we are formally introducing local chapters as a way of establishing a relationship between regional OpenStreetMap organisations and the OpenStreetMap Foundation. This is a hugely important step in the development of the OSMF.

The actual definitions, requirements and processes have been laid out. Read these, and more information, on the Local Chapters page.

Four New Tile Servers

Have you noticed faster tiles lately? Browsing the map on openstreetmap.org should now be even more responsive. Three new servers, started providing tiles over the last 2 weeks, joining a server which started earlier in the year.

Map tiles are delivered to users based on their GeoDNS location. The OpenStreetMap tile content delivery network (CDN) now supports EDNS-client-subnet to improve locating the closest region tile cache.

OpenStreetMap tiles are free for everyone to use, but should be used with moderation. If you are a high traffic site you should look into switch2osm.org to find out how to use the data and keep the tiles available for everyone.

Thanks to generous donations and active local community members, the OpenStreetMap distributed tile delivery infrastructure continues to grow.

The OpenStreetMap Foundation seeks additional distributed tile servers. If you would like to donate a tile server and hosting, please see the Tile CDN requirements page on the wiki. You can also support OpenStreetMap by donating to the OpenStreetMap Foundation.

The OpenStreetMap Foundation is a not-for-profit organization, formed in the UK to support the OpenStreetMap Project. It is dedicated to encouraging the growth, development and distribution of free geospatial data and to providing geospatial data for anyone to use and share. The OpenStreetMap Foundation owns and maintains the infrastructure of the OpenStreetMap project.
