Dear Prof. Perissin,
thank you for your quick reply! I tried to follow your advice to do it manually in Matlab with leggi and scrivi. With the leggi function it could read the data (Matlab showed all the values in the lines) but when I wanted to plot the Data (with plot(Data)) there were strange figures which did not correspond to the…[Read more]

It’s not necessary to choose a specific reference point for calculating the phase difference between two images. The zero phase can be arbitrary. However, a reference point is required to interpret the phase. So, you have this option in the view/export extended parameters module. We will add it later on also in the single interf processing module,…[Read more]

Hi Eva,
you are using the sw in a way we did not think of. Now (it’s an option we introduced about 8 months ago), you can remove the APS from interferograms (in the InSAR module) at the time of exporting your results (which means, after processing them). [in fact, this option is present also in the view/export extended parameters module] In other…[Read more]

Hi Anti,
you can find several discussions about the smart function in sarproz. Here some…[Read more]

Thank You Daniele
I understood it now
Agree, that this is weird, but possible, way to illustrate direction.

Hi Antig,
sun-synchronous near-polar orbits are almost parallel to the north-south direction. However, both when going up (ascending) and down (descending) the satellite path is slightly squinted to the west (as the earth rotates). if you draw this on a paper, and if you take the south direction as reference, u will see those angles (that you…[Read more]

Thank you very much for your rapid and detailed answers!

Cons: if your area is affected by temporal decorrelation/changes, keeping long temporal baselines will decrease the overall coherence.

For the cons you mentioned, I wonder if I individually corigester let’s say 50 images ; On the other hand, I select the same 50 images from the 280…

when I have a big dataset of 280 images, and want to process it in several subsets, can I coregister all 280 images one time, and then just select less images to form differenct subsets?

you can, it’s your option. Pros: all subsets will share the same master, so, pixels are directly comparable, you can merge/analyze results and have the full…[Read more]
