EUROPE: A project dubbed Cities at Night uses photos that were taken by astronauts who work at the International Space Station (ISS) to measure the amount of light pollution across the globe.
The aim of the project is to come up with a global color map of the Earth at night based on the photos that were taken from the ISS using standard digital camera.
The project, which started last summer and required the mapping of over 130,000 high resolution photos using geocentric details, does not only take into account the amount of light produced by cities around the world. It also looks at the effects of smaller sources of scattered light, which to date has not yet been quantitatively measured.
The ISS is the only location where it is possible to estimate the amount of the different types of lighting technologies that are tapped by cities worldwide and to measure the effects of light pollution on human health and the environment.
