Geolocating<br>Astronaut Photography
Explore Georeferenced Photos
Astronauts have been taking breathtaking, and scientifically valuable photographs of Earth since the earliest days of human space flight. The photos help scientists better understand the changing Earth, respond to natural disaster events, and measure various daytime and nighttime phenomena.
Yet, before being used in analyses, photos must be geolocated and registered. With an astronaut "in the loop" taking a photo with a handheld camera, the images do not inherently contain geographic metadata - they could depict any location within a 12.5M sq km circle centered on the ISS nadir point. We present methods to localize these images in both daytime and nighttime scenarios.

Dataset (AIMS-Night)
Astronaut Image Matching Subsets (AIMS)
To evaluate geolocation techniques, we introduce the Astronaut Image Matching Subsets (AIMS).
AIMS-Day
AIMS-Day contains 323 daytime astronaut photographs with varying focal lengths, obliquity (tilt), orientation (angles), and cloud coverage. The original AIMS task uses preselected reference images at different scales to evaluate localization performance. Download reference imagery for each scale below:

1.00x (45GB)
1.25x (31GB)
1.50x (29GB)
1.75x (21GB)
2.00x (20GB)
AIMS-Night
AIMS-Night contains 363 nighttime astronaut photographs with varying focal lengths, obliquity (tilt), orientation (angles), and acquisition year. They are distributed as follows:
The AIMS-Night does not use reference images, and instead measures the number of images localized within 50km of their ground truth center point. Download the set and associated metadata here:
