Discovering forgotten glacier images in a new glance (DEFOGGING)


Glacier retreat is one of the most visible signs of ongoing climate change, and repeated glacier photography is possibly one of the most immediate way to visualize and communicate the alarming rate of this change. This project sets out to guarantee long-term accessibility to a unique record of glacier photographs that have been collected over the years. Starting from a pool of over 50,000 images available at the project's host institution, the aim is to integrate these historic documents in the Image Archive of the ETH Library. The images will be indexed, digitised and georeferenced with the help of volunteers, and made accessible through ETH's E-Pics platform. This will ensure long-term accessibility to an unique set of observations, thus creating added value for both researchers and the general public.
