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 with useful information, the Humanitarian OpenStreetMap Team (HOT) has been making progress as well.
I have spent some time to develop a website that visualizes the latest changes to the OSM map (utilizing changesets) in the Philippines and hope that it helps to determine areas that might be already worked on, while other areas are lacking any new information. You can find the map here: http://resultmaps.neis-one.org/osm-typhoon-haiyan-2013
Additional information can also be found in the OSM Wiki and for all German fellows at the Wochennotiz blog, in case you are interested in actively contributing and helping the disaster response teams. Any mapping efforts are much appreciated!
