New SotM logo!

SOTM logo

A New Logo for the State of the Map from

“The logo for this year’s State of the Map was designed by Sofiya Merkulova and was chosen from over 35 designs. The SOTM09 organizing committee felt that Sofia’s design was powerful, fun and conveyed the global nature of OpenStreetMap and SOTM09.

The organizing committee’s congratulations go to Sofia and our thanks go to all of the competition entrants. It was not an easy choice to make, but we’ve now got a great logo for a conference that is shaping up to be the best State of the Map yet.

The logos are available under a Creative Commons Licence. You can download a bundle that includes different resolutions and greyscale versions here.”

Some changes to OSM

With the upcoming API 0.6 the technical team have made several discoveries of the overall performance of Ruby, MySQL and the code used to run OSM. They’ve found that with MonetDB and the cherokee webserver we can speed things up considerably, and reduce the CPU count. This system has been reliably tested by Tom Hughes and Matt Amos as hundreds of times faster than the current setup. The speed increases are incredible to the point where the DB almost seems to know map edits before they happen and the HTTP and DB transactions tend to 0ms over time, and 0% of the XML API transaction itself.

Of course partly this is because it’s been re-written in C++ and all clients, particularly potlatch, now will be using the new binary protocol. Richard Fairhurst, the potlatch dictator, has been in close and positive contact with the authors of the new system to make this shift and has been working openly to encourage new developers to help rework potlatch. Improvements will include basic usability.

Unfortunately some of the work has pushed back the API switchover and a working group has been set up to decide on a date to announce the new date for switchover.

To counterbalance this bad news however, there is a silver lining – the license process has completed. From today the OSM database is available under the NDL [1], a variant of the original ODbL and closely similar in purpose and intent of the Duke Nukem Forever release process, which has shone industry-wide as an example of best practices.

OSM WordPress plugin

Michael Kang writes:

faktor is a group of photographers, we started an open photoproject in 2004, to collect one photo for each location. Last month we decided to add geo data and geo links on this site. To handle this I wrote a plugin and after some lines I thought it could be usefull for others, too.

To add a map into your wordpress blog you just have to install the plugin and use the shortcode like:

[osm_map Lat=”37.5665″ Long=”126.9779″ zoom=”5″ width=”450″ height=”300″]

in your post/page (no configuration is needed).

Details and the plugin is here:

SOTM needs a logo!

From stateofthemaporg:

The SOTM working group is pleased to announce a call for logo designs. Our existing logos have served us well and the time is right to look further afield to make sure we have the best design possible. We’ve put together a Design Brief which outlines what we’re looking for in a logo. We invite you to either build a logo yourself, rope in some friends/co-workers or use a site like and a spare £/$/€50 and get a freelancer to have a go.

The logo must be licensed CC-BY-SA and received by email within two weeks (by midnight Wednesday 8th April UK time). The team will decide by vote the logo to go with.

The winning entry will be rewarded with a full weekend ticket to SOTM!

The SOTM team can’t wait to see your entries!

OSM passes 100,000 users!

A great day for celebration! Sometime during Monday 16th March 2009 OpenStreetMap gained it’s 100,000’th registered user account!

It’s been a fantastic journey since 9th August 2004 when User:Steve registered the domain and started the project. Today we have a fantastic set of sysadmins keeping the OSM clockwork going, brilliant developers and a massive and stunning community building… the map.

Our map goes from strength to strength with such fantastic detail being built it’s unreal. Check it out!

Now, roll on our 1,000,000’th user please! Help OSM get there by submitting a talk to our upcoming conference – it’s going to be a blast!

OSM needs new servers

Our first set of ‘real’ servers was installed by me (SteveC), Nick Black and Nick Hill utilising the latest in safe server transport – Nick Hill’s overloaded Peugeot. Here they are being modelled:

Today we’re kicking off a funding drive to raise £10,000 to buy new API database servers for the upcoming new API and server software which we call “0.6” as it’s the 6th version. Specifically we’re after a 3U Rackmount server, 2x Quadcore, 24GB RAM, 10x SAS 15kRPM disks.

OpenStreetMaps exponential growth since day one has led to increasing demands on the hardware and software clockwork which make it tick day and night, and this funding drive will put us in a fantastic position to cross the next hurdles of mapping the planet. We have incredibly dedicated volunteer sysadmins and coders building OSM today, so let’s give them the best tools for the job to continue building the most detailed map of the planet.

So please consider heading over to and chip in some cash for the cause. We’ll keep you up to date with the process of buying, setting up and installing the new hardware.
