Hi,
i am interested to DInSAR processing.
I would like to have more informations about the procedures to select and download pairs of images suitable for Differential Interferometry.
Is there any tutorial?
Thanks
About the selection of images
A tutorial is given here
https://saredu.dlr.de/unit/insar_deformation
It is based on NEST so some parts of the GUI look a bit different now but in general these are your required steps.
Sir,
I am having pair of data, dated 01/10/2016 and 18/02/2017 (DUAL POLARISATION) .Can this be used for interferometry?
Also. i have polarimetric data of dates 02/04/2016 and 28/05/2016. Please tell whether any of these can be used for interferometry for dem generation.
Thanks
Impossible to say as it depends on orbit track, wavelength, land-cover type etc. Please study the InSAR tutorials & online courses so you gain more understanding into SAR interferometry.
as already often mentioned, this topic is a good start for all kinds of questions regarding DEM generation:
I have a query… The displacement map which i have obtained using DInSAR technique has values ranging from +1.05 to -1.006. How should i infer it??
Have a look at these threads,
If the relative orbits are the same, can you understand that the incident angles of a study are the same? Thank you!
this depends on the perpendicular baseline, if the angle is identical, InSAR would not be possible.
