Facebook has unveiled disaster maps, which can help provide food, water, and medical supplies to people struck by natural disasters.
“After a flood, fire, earthquake, or other natural disaster, response organisations need accurate information,” said Facebook.
Traditional communication channels are often offline and it can take significant time to understand where help is needed.
Facebook can help organisations paint a complete picture of where affected people are located.
To do this, Facebook’s disaster maps use aggregated, de-identified Facebook data to provide multiple types of maps during disaster response efforts.
- Location density maps show where people are located before, during, and after a disaster.
- Movement maps illustrate patterns of movement between different neighbourhoods or cities over a period of several hours.
- Safety Check maps are based on where the community uses Safety Check to notify their friends that they are safe.
