  • Filtering OpenStreetMap Changesets by a Specific Comment

    In my last blog post I showed that OpenStreetMap (OSM) changesets offer a great opportunity to visualize the latest changes to the OSM map or to compute some up to date descriptive statistics of a particular region (Typhoon Haiyan OSM Response Map). Oftentimes OSM contributors use tags, comments or hashtags in their changesets to provide…

  • Typhoon Haiyan OSM Response Map

    As you may know by now, the Philippines have been struck by one of the largest Super Typhoons ever recorded. Many casualties are expected (especially in Tacloban) and even more people are in need of help. While some of us have been busy working with the “Stand By Task Force” to analyze and geolocate tweets…

  • It’s about time – OpenStreetMap Contributor Activity Report 2013

    One and a half years ago (end of 2011), one of my open access publications (“Analyzing the Contributor Activity of a Volunteered Geographic Information Project — The Case of OpenStreetMap”) was published. I thought it was time to update this information with some new statistics. Between the end of 2011 and July 2013 the number…

  • Distribution of Active Users in OpenStreetMap – Oct-Nov 2012

    Two years ago, we created some maps which showed you the number of users per country for a timeframe of one month. Maybe some of you remember that the highest concentration of active contributors in relation to the countries’ population …

  • I Like OpenStreetMap (OpenLayers Plugin)

    A few months ago, Frederik Ramm posted an idea on the German OpenStreetMap mailing list about a new (stochastic) approach to OSM data quality assurance. His idea was to create a way to allow users to “like” or “dislike” a specific region on the OSM map …

  • New OSM Contributor Feed

    The OpenStreetMap project keeps attracting more and more new members that register and start contributing their data to the project. In one of my last blog posts I presented a website which shows the location …

  • OSM-GPS-Grid-Map

    More than 6 weeks ago, I wrote a blog post about “Which country has the most OpenStreetMap GPS Points?”. You might remember that Russia and Germany provide the most OSM GPS points. Now, in a second step I created a worldwide grid …

  • Which country has the most OpenStreetMap GPS Points?

    Some of you might already know that OpenStreetMap released a first bulk GPS point dataset last week. It contains almost 2.8 milliard (or for readers in the US 2.8 billion) points and is provided in its raw format …
