❓ Réponse de l'image mystère : il s'agit de la Guyane française photographiée par le satellite #Sentinel1 du programme #Copernicus.
Les couleurs proviennent de la combinaison de deux polarisations de l'image radar, auxquelles une couleur a été attribuée et convertie en un seul composite.

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. :)

🚀 EO-Tools 2025.2.0 is out!
No new features this time, but several fixes and code improvements.

🔹 Breaking change: to make parameter names more consistent, several function calls have changed—check the version notes and API reference for details.

The way to Sentinel-1C operations
This article describes the steps from the launch of the satellite to the distribution of the images.

On 27 January 2025, Storm Herminia struck parts of Spain, Portugal, France, the UK, and Ireland.

This image, by #Sentinel1, shows the flooded areas south and east of Rennes.

The way to #Greenland passes through #Sentinel1.

Interesting look at the Mississippi River in #Sentinel1 #SAR adjacent to Herculaneum, MO. 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.

Still concerning the L.A. wildfires observed through interferometric coherence evolution, a descending pass #Sentinel1 A image was acquired ~12hours after the ascending one.
So, here is a twelve-days interferometric coherence evolution 12 hours apart.
There is certainly slope effects due to incidence angle variation but some losses of coherence in twelve hours are clearly visible.

Concerning the L.A. wildfires, here is a quick view of #InSAR coherence evolution between #Copernicus #ESA #Sentinel1 images of December 16 2024, December 28 2024 and January 9 2025.

Burnt area between last two dates are characterized by strong and abrupt coherence losses.
This gives an idea of the burnt surface in a twelve days delay.

📢Our research on mapping societal material stocks 🏡🚗 is now featured on the #CDSE page as a use case! #sentinel1 #sentinel2 https://dataspace.copernicus.eu/cases/national-scale-mapping-societal-material-stocks-using-copernicus-data

Now that #Sentinel1-C is in orbit when can we expect the first data?

The commissioning phase is expected to take about four months, although it may extend further. For reference, Sentinel-1A took six months from its launch in April 2014 to become operational in October 2014. Thus, a little more patience may be required.
