Facebook expands its population density maps to the Asia-Pacific region

The above map shows the distribution of women of reproductive age (ages 18-49) spread across Tanzania, drawn from a combination of census data and satellite imagery. Image: Facebook.

Facebook has published new population density maps covering most of the African continent and countries of the Asia-Pacific region in June 2019. Using artificial intelligence (AI), these maps help organizations to respond to natural disasters, and scientists to assess the impact of climate change and urbanization on people’s lives. As soon as almost the entire world population is covered by the project, population distribution in remote areas will be better determinable by humanitarian agencies.

New map explores ocean tectonics from space

Marine gravity model of the Central Indian Ocean

Scientists at the Scripps Institution of Oceanography at the University of California created a new seafloor map based on satellite data that discloses previously unaccessible features on global earthquakes, spreading ridges and faults.

The new instrument explores the deep oceans' structure and ongoing geophysical processes by capturing gravity measurements of the seafloor, which are derived from altimery data recorded from ESA's CryoSat-2 and NASA's Jason-1 satellites. The authors state that "the map provides a new window into the tectonics of the deep oceans".
