Help map Earth's lights from space and combat light pollution

5 challenges are open — join one and your work counts for a shared goal.

Our Mission

This application is designed to help georeference images taken by astronauts aboard the International Space Station (ISS). The goal is to create a global map of Earth's lights at night to measure and track light pollution. By accurately aligning images with geographical coordinates, the app contributes to valuable environmental data collection, which can be used for scientific research, monitoring light pollution, and understanding its impact on ecosystems and human health.
