Olivier D'Hondt 🛰️🌍🌱<p>It's hard to get proper visualizations of SAR imagery due to high image dynamics. I have spent quite some time tweaking this one, which represents the parameters of the dual-pol H-alpha decomposition on the new Sentinel-1C sensor! Disclaimer: it's visually compelling, but probably not physically accurate. :)<br><a href="https://framapiaf.org/tags/Sentinel1" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Sentinel1</span></a> <a href="https://framapiaf.org/tags/eo_tools" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>eo_tools</span></a> <a href="https://framapiaf.org/tags/SyntheticApertureRadar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SyntheticApertureRadar</span></a> <a href="https://framapiaf.org/tags/EarthObservation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>EarthObservation</span></a> <a href="https://framapiaf.org/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>python</span></a> <a href="https://framapiaf.org/tags/RemoteSensing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RemoteSensing</span></a></p>

In this multi-temporal false-color composite, the yellow line is the rough and exposed ice edges left in the wake of a ship breaking through the much smoother sheet ice which appears black. The blue features in the water are ships that were acquired in summer time images, ghosts of shipping past.</p>
