Crowdsource Mapping Helps Recovery Efforts In Philippines

The United Nations says 11 million people are affected by Typhoon Haiyan, which hammered the islands a week ago today. The death toll is now more than 3,000, and the survivors are still struggling to get the food and water they so desperately need.

Blocked roads, destroyed buildings and downed telecommunications systems are making it difficult for relief workers to reach some of the most devastated regions of the Philippines.

But more than 900 people are lending a hand remotely by collaborating on online maps, through the OpenStreetMap network. The maps use satellite technology and the knowledge of the public to help relief organizations, like the Red Cross, know where buildings and roads are located and how and where to best deliver supplies.
