Cities at Night is a citizen science project that aims to create a map, similar to Google maps, of the earth at night using color pictures with 10 times more resolution than it was available for the pulic so far.
With this database of almost half a million photographs we work on organizing, cataloging, georeferencing and calibrate for science research purposes.
Currently, night satellite images are a powerful source of information in different fields of study:
- Light Pollution
- Human Health
- Population economics
See the results obtained thanks to Cities At Night:
Lost at Night App
Do you want to do Citizen Science?
Citizen science is a tool for scientific and educational research. Once nocturnal images are identified we need to know where are the located. With this application you can help us to know the City. Lost at Night is our current working app.
Help the project while recognizing cities from various beautiful pictures taken from space!
Cities at Night is a collaborative project, with access to all data. If you have any questions contact us.
What do we do with the data?
We publish the data openly, always been sure of not collecting any personal data of the volunteers. We use the data for scientific research on light pollution.
Where is the project data stored?
The data is stored at the app while we are still collecting it. Later, is uploaded to our Zenodo community. The data we have of the app Lost At Night currently working is here.
Can I participate in the project?
We need volunteers to help us classify, identify the image locations and then in the georeferencing process. All work will be recognized as co-author (in the case of paper and the degree of involvement) or as acknowledgment.

Light pollution awareness
Didactic Unit – Light Pollution
This document aims to generate social awareness about the problem of light pollution, bring scientific research closer to schools and of course encourage young people to participate in our project.
This teaching material will allow you to work in the classroom with high school students with ages around 14 years old.
It also reviews the basic lines of the Cities at Night project and highlights the potential of satellite images to locate light pollution sources and monitor their evolution over time.
