For their study of the earth's glaciers evolution, ie 200,000 glaciers, over a 20-year period (2000-2019), scientists from the Laboratoire d'Études en Géophysique et Océanographie Spatiales (LEGOS), Romain Hugonnet and Etienne Berthier, and their collaborators have computed 1,000,000 stereoscopic images from the ASTER database. Once compiled, stereoscopic images enable scientists to measure the glacier height and compare their evolution from year to year.
This book compiles a sample of 250 images from the Arctic and Antarctic zone, selected by Etienne Berthier and Grégoire Eloy. 4,000 volumes like this one would be necessary to publish all images computed for the study.

1,000,000 images from the ASTER satellite were needed by scientists from the Laboratoire d'Études en Géophysique et Océanographie Spatiales (LEGOS/OMP/CNRS), Romain Hugonnet and Etienne Berthier, for their study of the evolution of the world's 200,000 glaciers over a 20-year period (2000-2019), published in the journal Nature on April 29, 2021. Once assembled, the pairs of stereoscopic images make it possible to determine the altitude of the glaciers and compare their evolution from year to year. In 2021, photographer Grégoire Eloy teamed up with glaciologist Etienne Berthier to publish a series of image books from the Aster database. This first 520-page volume brings together a selection of 250 images representative of the Arctic and Antarctic zones. The second and third volumes will be published in 2023 and 2024. A total of 4,000 volumes would be needed to publish all the images analyzed by the scientists' algorithms for this unprecedented study.
