The Peace Corps and Humanitarian OpenStreetMap Team have been collaborating for over a year. To me its a natural connection. Peace Corps Volunteers (known as PCVs) spend at least two years in country, working closely with communities and local organizations. One of the first things a PCV does is make a map in their community, along the lines of a traditional, paper based participatory mapping exercise. A PCV today is connected, a higher percentage have access to mobile networks than running water; and that's changed their connection to their fellow volunteers, home, and communities.

An unprecedented number of unmanned aerial vehicles (UAVs) -- drones -- have been used to collect imagery after typhoon Yolanda/Haiyan. But little coordination between projects appears to have occurred. Many types of response and recovery organizations can benefit from these "bird's eye" views of the typhoon affected areas.

Thanks to all the contributors who helped finishing mapping Bangui and Zemio last week!   I made a review of the progresses of mapping cities and towns in CAR with OSM as well as the potentials. The results are synthesized in this uMAp.

On Friday I presented a talk at the Open Data Institute on "Typhoon Crisis Mapping With OpenStreetMap". You can see the slides and notes at that link, and even an audio recording. The talk was an intro to OpenStreetMap and H.O.T.   Maybe you've heard all that before, but I also tried to look back on our recent efforts responding to Typhoon Haiyan in the Philippines, and I thought I would share these graphs of editing traffic here:

South Sudan is currently a top humanitarian focus if we consider the number of publications over the week on ReliefWeb.  Since violence increased in the country by the end of December, we started monitoring and working to provide baseline data for the humanitarian response.

HOT is fortunate to have generous supporters around the world. We are a small non-profit that is mainly funded upon projects. Every contribution and donation is a gift which helps us in our mission to bring OpenStreetMap to humanitarian response and socioeconomic development.

Many of us have spare quiet moments in the Christmas and New Year holiday season. We've gorged ourselves on food, cleaned up wripped apart wrapping paper, and maybe had a little time to relax and reflect. Now, If you're looking for something to occupy your time these days as your energy builds for the new year, you're more than welcome to join in and map HOT tasks, and make a solid contribution to places in humanitarian crisis right at this moment.

As part of our obligations as a 501(c)3 registered organization, we make our financial filings (known as "Form 990: Return of Organization Exempt From Income Tax") available for public inspection. As an organization, we are dedicated to transparency, to our community and members, and hope these documents are helpful to understand HOT's operations. HOT's 2012 returns are posted at

OpenStreetMap began with people walking, biking, and driving around their neighborhoods, surveying data using GPS to map. Starting in 2007, satellite imagery became available for OSM volunteers to trace features, complementing on the ground survey. Imagery was first provided by Yahoo, and presently through Bing, two companies generously taking a chance with our wild idea to voluntarily map the whole world.

I spent four days this week in Manila with the Global Facility for Disaster Reduction and Recovery unit of the World Bank. The impetus behind the trip  was to see how the OpenStreetMap data could feed into the recovery process post Typhoon Haiyan/Yolanda. During my short-time in Manila I met with a few different groups. It was great to hear that the OpenStreetMap data was useful and that organizations would continue to appreciate it being updated. This would not be without the support of the over 1500 volunteers who have helped create data and the activation coordinators Maning Sambale, Andrew Buck and Pierre Béland. As well as the many others that played roles in other ways.
