And here are my very first results with these new #NASA #NISAR data.
I had to debug a few my NISAR data reader to correctly read the frequencyB layer.
Now it is working.
Here are both frequency A and B differential interferograms on Ethiopia showing the November 2025 volcanic eruption.
Still playing with newly released #Sentinel1C image.
An Extended Wide swath (EW) image was acquired on south #Groenland by #Sentinel1C on February 6, 2025.
The day before, a classical Interferometric Wide swat (IW) image was acquired by #Sentinel1A.
Both images were acquired in polarisation HH - HV.
I coregister both images like it was an interferometric #InSAR pair and make this short animation showing sea currents variation in this one-day interval.
So, my InSAR soft compliance with #Sentinel1C strip map (SM), Interferometric Wide swath (IW) and Extended Wide swath (EW) acquisition modes is now fully verified.
#AmsterToolbox (https://github.com/AMSTerUsers/AMSTer_Distribution)
This AMSTer Software is dedicated to automatic SAR/InSAR mass processing for amplitude, coherence or deformation time series. It can also perform single interferometric tasks. It is based on C and ...
Yesterday, it is to say less than two month after #ESA #Sentinel1C 🛰️ launch, a first release of images was made available on #COPERNICUS data space environment to allow users to test their software compatibility.
So, I tested my soft, the AMSTerEngine which is at the core of the AMSTer Toolbox for #InSAR #timeseries processing.
And here is the very first result using a #Sentinel1C - #Sentinel1A image pair acquired on January 17 and 16 respectively on Brest, France.
Consequently, AMSTer Tool box is #Sentinel1C compatible!
This is just normal since #ESA kept the same format for these new data. However, knowing from long that the only reliable stuff in computing is the on/off button, it is quite a relief.
