A Color Map of Earth at Night to Monitor Light Pollution
summary
Describes creating the first color map of Earth at night to monitor light pollution, using astronaut photographs from the International Space Station because current satellite products are black-and-white. Explains the impacts of light pollution on health, economy and heritage, and presents the approach combining computer vision and citizen-science projects (Cities at Night and RALAN-Map) to produce a colored nighttime map of Europe and beyond.
