How to Participate

The citizen sciende project Cities at Night  involves three main tasks that anyone can join:
Task 1: Classify

This task focuses on identifying unlit areas and comparing them to those that are strongly impacted by artificial light. You will help classify the images from the ISS, whether they are auroras, glows or indeed correspond to a city or country.

Sometimes, even astronauts aren’t sure which part of the world they’ve captured in a photo. In this task, you’ll help identify which cities or regions are depicted in these images. It’s like solving a mystery, and your help is crucial in filling in the gaps!

Once we know the location of the city, the next task will be the georeferencing process. This will allow us to link the identified photographs to a physical map.

You can choose any of the 3 tasks, each of them is independent of the other. Or you can participate in all 3 tasks

Lost At Night

Lost at Night is the latest app developed alongside the Plan B Project.

This application is designed to help georeference images taken by astronauts aboard the International Space Station (ISS).
