SAR Map of the Antarctica

Sat, Nov 25, 2023

Here, I used a detailed Synthetic-aperture radar at a resolution of 125m to visualize the surface morphology of Antarctica.

This was a tricky one - so few data available. I am exceptionally curious about others’ posts! As for myself, I ended up simply visualising a 125m resolution SAR image of the whole continent provided by the National Snow and Ice Data Center. The false color tones correspond to different morphological properties, as the documentation puts it:
