RALEIGH, N.C. (AP) - In a disaster like Hurricane Florence , when emergency responders need to pinpoint trouble spots where people need to be rescued, other relief agencies that offer long-term help need to know where evacuees fled to escape the danger.
Some of those charities are using a disaster mapping tool recently developed by Facebook to help do that in North Carolina. The tool provides anonymous data to show locations that are shedding people and those that are gaining them. It tracks the movements of groups, but not individuals.
