Check out this graph of contribution:

It’s built, as explained here:

In the new draft OpenStreetMap Contributor Terms, an ‘active contributor’ is defined as:

a contributor (whether using a single or multiple accounts) who has edited the Project in any 3 calendar months from the last 6 months (i.e. there is a demonstrated interest over time) …

This is a visualisation of the edits of the 8173 ‘active contributors’ (as of 1/2/2010) across the last three years. For each contributor a mark is placed along a horizontal line under each day that they contributed an edit. At the top are contributors with almost daily edits (within the last six months) and, at the bottom, those that only just meet the criteria. The vertical axis has been scaled from 8173 to 1600 pixels. There is a fairly strong correlation between recent and historical edit intensities.

This was calculated from the planet changeset dump, and assumes that a changeset was edited on every day if it was open for more than one day (rare). It regards each user id as an individual, so does not take account of a contributor using multple user accounts.

About 53 million tiles were served yesterday

From 87071 unique IP addresses

Nearly 8 million referrers used the OSM tile server a day

From about 2489 different domains….

OpenGeoData is moving to posterous and so your feeds will move. The blog URL itself will remain static – opengeodata.org.

• RSS feed will move to here: http://feeds.feedburner.com/Opengeodata
• Podcast feed is now here: http://feeds.feedburner.com/OpengeodataPodcasts

Now that the feeds are with feedburner, they should remain static (they haven’t moved in 4 years so far anyway).

WordPress has become too much of a PITA to manage for many reasons and posterous is just a pleasure to use. Unfortunately the wordpress to posterous import is not complete yet though. The basic problem is that in lots of posts here on opengeodata, we link to content (like podcasts and pictures) which reside here on opengeodata. Posterous isn’t clever enough yet to grab all of those things and host them… so if I did the import and then changed the domain over, we’d lose all of that media. I have unsuccessfully asked for help fixing this with a script and using the posterous and wordpress APIs or something.

Thus unless anyone wants to help, this entire blog is going to move to old.opengeodata.org and will be mothballed. A new blog will appear at www.opengeodata.org powered by posterous. Anyone with existing accounts who wants to post to the new blog should get in touch, it’s all pretty easy. The good news is that we can at any point in the future import the old content, or at least I hope so anyway.

So long, and thanks for all the maps!

Pretty cool, huh?

You might be interested in the results of a meeting the USGS held on VGI and its implications. Minutes, presentations etc are over here.

The Washington Post attended a recent OpenStreetMap mapping party.

New York Times mentions OSM and Haiti. As does New Scientist.

The Guardian brings everyone up to date on OpenStreetMap’s progress.

Also, interesting article by Nat on opening up data.

“We are excited to be adding support for OSM to the DecisionTree product. I am a big fan of the OpenStreetMap project. The effort has proven enormously successful at developing and maintaining a global map that can be shared and used for a wide range of purposes,” said Avencia CEO Robert Cheetham. “We’re thrilled that we have been able to extend the ArcGIS Flex API to add support for OpenStreetMap.”

While we’re at it, there’s a neat recent ESRI blog post on using OSM in ESRI products here.
