In a disaster like the earthquake in Nepal, information is key. Knowing where roads are passable or where it’s safe to land a helicopter full of supplies can make a huge difference for relief workers. One group is working to make sure those maps are complete. The Humanitarian OpenStreetMap Team coordinates volunteers around the world to edit maps to help agencies like the RedCross and World Bank respond in a crisis. Since Saturday, more than 1,700 people around the world have edited maps of Nepal. Blake Girardot is a board member for the group, and he joins us with more.
