Citando:
"REMA "provides the first high-resolution, high-accuracy terrain dataset of approximately 98% of the contiguous continental land mass of Antarctica, extending [from the South Pole] to 88°S," the project website states.

The map, built with data extracted from satellite imagery, is not just static. Ongoing input will provide scientists with the most detailed overview of shifting landscape patterns in Antarctica ever—from changes in snow cover, ice flow, glacier thickness, and all manner of geological activity."
