Volunteer Internet Mapmakers Improve Outcomes In Nepal

The night after the earthquake hit Nepal, people feared to sleep in their homes, worrying about powerful aftershocks toppling the few buildings left standing. They slept instead in tents, in the street or in city parks. Meanwhile, it rained and rained. The storm soaked people's possessions and chilled those without shelter. But it also kept Kathmandu from being seen from above — and this was more of a problem than it might seem at first. It's become a regular occurrence: Whenever there's a natural catastrophe, a team of "crisis mappers" activate around the world.
