  • 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.

  • The State of the Map. United States. Street Network. 2013

    Last year we wrote a journal paper in which we analyzed the OpenStreetMap (OSM) dataset of the United States which was published on May 28th, 2013 in the Transactions in GIS Journal.

  • Introducing OpenStreetMap Contributor Activity Areas

    One month ago I wrote a blog post about a new website which allows you to see other OpenStreetMap contributors in your area. Overall the feedback was very positive, thank you very much for that! However, now it is time for a new extension to the “How did you contribute to OpenStreetMap?” (HDYC) webpage. As…

  • The OpenStreetMap Contributors Map aka Who’s around me?

    The wait is over! As I mentioned in December, I have been working on an interactive online map, which shows you all volunteers of the OpenStreetMap world on a map. The first three layers contain …

  • OSM-Gravatar, Changeset changes & Way-Tags @ HDYC

    After my latest updates to the “How did you contribute to OpenStreetMap?” website, some users asked me if I could add the new OSM gravatar to it. Starting today, you can find your OSM-gravatar from …

  • 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 …

  • Overhauling “How did you contribute to OpenStreetMap?”

    My last update about the HDYC website is a few months old now. For those readers who do not know what HDYC is: “How did you contribute to OpenStreetMap?” is a webpage which shows you in detail how long, when, where a member of the OSM project contributed to the project and which tools she/he…
