What is Feature Hunter?

The Earth Science and Remote Sensing unit at NASA's Johnson Space Center maintains an enormous collection of over three million astronaut photographs of Earth, spanning manned spaceflight from the Mercury missions to today's ISS missions.

These photos can be vital to researchers across many fields, but many are inaccessible because they lack labels for common features like islands, volcanoes, and rivers. Feature Hunter is an important part of the creation of a machine learning algorithm aimed at labeling previously uncategorized Astronaut Photography.

Machine learning requires large sets of training data to produce accurate results. Feature Hunter users will help develop this training data by viewing images, determining whether or not a feature or features are present, and identifying features by placing bounding boxes around them.
