Why Facebook Is Mapping Human Settlements across the Globe

An estimated 10 percent of the world's population doesn't have access to the Internet. Facebook's Connectivity Lab is trying to find a way to bring isolated communities online, but in order to do so, it needs to know where they live.

An estimated 10 percent of the world's population doesn't have access to the Internet. Facebook's Connectivity Lab is trying to find a way to bring isolated communities online, but in order to do so, it needs to know where they live.

The construction of its Aquila drones was the first step. These unmanned solar-powered drones have a wingspan of a Boeing 737 and can spend months in the air, beaming down Internet to ground-based hubs. Through these drones, the Internet can be made available in remote areas where the infrastructure would be too costly or difficult to build. Google has been working on a similar balloon-based project in Indonesia. However, the Connectivity Lab needs to know where to send these drones — where they'll do the most good.

So, a team of researchers began looking at population distributions across 20 different countries from maps provided by the World Bank and Columbia University. They used these third-party images and fed them into their neural network. Through new machine learning techniques, they trained a computer to sift through billions of images in order to identify population centers. These new maps show populations on a much finer grid, just 10 meters across.

“In total, we analyzed 21.6 million km2 of the priority countries. For this we processed 14.6 billion images with our neural network; this is more than 10 times as much as all the images analyzed by Facebook on a daily basis,” according to one report.

These maps will help guide the Connectivity Lab to identify what areas need which kind of support, whether it be an aerial Internet-delivering drone or a ground-based solution. Facebook says once the maps have been reviewed, this data will become open to the public later this year.

“These higher-resolution data will be useful in optimizing the location of health and sanitation facilities, planning energy and transportation networks, improving resource management and access, and facilitating humanitarian assistance,” Robert Chen, director of Columbia’s Center for International Earth Science Information Network, said to Technology Review.

Can the keto diet help treat depression? Here’s what the science says so far

A growing body of research shows promising signs that the keto diet might be able to improve mental health.

Mind & Brain
  • The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
  • Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
  • Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
