A new approach called social mapping provides rescue teams with a detailed, data-driven map of what they should be doing, and where.
Anca Toader's insight:
"In disasters like the typhoon that slammed into the Philippines, sifting through a barrage of confusing and conflicting on-the-ground reports is one of the first problems facing rescue teams. Social-media sites such as Twitter and Facebook can make matters worse. All too often, users recycle what others have posted or retweeted without adding any fresh information. Sorting through all the noise is too much for individual agencies to handle on their own. So Swiss-born Patrick Meier is gearing up to attack the problem with a new approach called social mapping: Using a combination of volunteers and algorithms to filter the chaos and to provide rescue teams with a detailed, data-driven map of what they should be doing, and where."
