Facebook: The social media giants with billion of users is a global platform that connects almost a third of the world population.
Nowadays Facebook is a key resource and plays a major role in the natural disasters and terrorism, where it provide support for relief organization that helps in rescue. So the social network then becomes a very useful tool to collect information which previously appears as Safety Check feature, widely used in terrorist attacks in various parts of Europe.
In a natural disaster like tsunami, earthquake or floods, communications are often shattered and the social network becomes a powerful way to understand the extent of the danger and coordinate the efforts of the rescuers.
That is why Facebook has just announced the creation of three new types of maps designed to help the authorities find the survivors of a natural disaster.
The first map (Location density maps) uses the location to allow rescuers to know where they were people before, during and after the natural disaster. This will make it possible to identify the areas that have been most affected and damage.
The second map(Movement maps )uses satellite imagery to track the movements in a given period. With this tool to help organizations to better coordinate their efforts, identify locations or get directions for evacuation. Facebook believes that comparing its own data with satellite imagery will help organizations to intervene locally.
The third and final map(Safety Check maps) is based on the Safety Check, and is designed to allow people to share with other safe places.
Safety Check maps are based on where our community uses Safety Check to notify their friends and family that they are safe during a disaster. We are using this de-identified data in aggregate to show where more or fewer people check in safe, which may help organizations understand where people are most vulnerable and where help is needed.
During the floods in Peru in March, Facebook was able to know where people were, where they were moving to safe locations and doing their safety check to reassure their loved ones. This type of information will “help intervention agencies help people more effectively and efficiently and save more lives.T
Facebook state that these maps will be available only to Unicef, Red Cross and World Food Program (WPF).
We are sharing this information with trusted organizations that have capacity to act on the data and respect our privacy standards, starting with UNICEF, the International Federation of the Red Cross and Red Crescent Societies, and the World Food Programme. We are working with these organizations to establish formal processes for responsibly sharing the datasets with others.
Over time, we intend to make it possible for additional organizations and governments to participate in this program. All applications will be reviewed carefully by people at Facebook, including those with local expertise.
