Facebook maps can help first responders
Facebook spends a lot of time and effort trying to determine where its users are located, and it looks like their pursuit could lead to relief for victims of natural disasters. According to TechCrunch, Facebook will be providing three different sources of information to groups like UNICEF, the Red Cross, and the World Food Program to help them provide aid where it is needed more easily.
There will be location density maps which roughly show where people are becoming more or less concentrated after a disaster. Movement and Safety Check maps will show how and where people are moving and when they have reached a place they feel safe, respectively.
Although there are a few possible privacy concerns with the technology, it is clear that anything capable of saving lives should be considered necessary.
