In the aftermath of a disaster, lack of information about the affected areas can hamper relief and recovery efforts. Open-source mapping tools provide a much-needed low-cost high-tech opportunity to bridge this gap and provide localized information that can be freely used and further developed.

A week ago, devastating typhoon Haiyan hit the Philippines. As the images of the horrifying destruction emerge, there is a clear need in accessing localized high-resolution information that can guide communities’ recovery and reconstruction. Responding to this challenge, over 766 volunteers have been activated by the Humanitarian OpenStreetMap Team (HOT) to create baseline geographic data which can be freely used by the Philippine government, donors and partner organizations to support all phases of disaster recovery.
