Sorry if I confused you. And my apologies for saying that DInSAR may not give reliable results.
Below is the results I obtained for the road line (600m away from the main AOI) which we suspect that is not affected by the tunneling activity. This is related to my previous post. Our assumption is, since this road line it is not affected by the tunneling activity, it should not have any displacement (say DInSAR should give zero values). But I wonder if this is absolutely true when doing DInSAR. That even if we have absolute no ground movements, DInSAR might still give non-zero measurements. I know there are other factors to be considered here as you have enumerated awhile ago.
We’ve also thought of these factors, considering that the area is near the shoreline. We lack information about the site, also the start and the suspension of the construction after some structural damages were observed.
Anyway, thank you for your immediate responses.
I couldn’t apply with PSI/SBAS for this one now because I haven’t started it yet. But thanks for the suggestion. If time permits and my supervisor does not rush to have results, will probably consider PSI/SBAS.
One more thing, from my displacement map (as shown below), I do get some times this kind of regions at the edges (blue in this case). Is this normal?
Thank you so much! I am now relieved. Those regions bother me a lot.
Finally, for today (heheheh), I just want to ask how do I properly use the tool shown below? I want to determine from SNAP the distance between two points (pixels). Whenever I try to use it, it just keeps creating series of connected points, and I couldn’t see any measurement.
Iam new in radar interferometry .Ihave two slc images at 1-12-2017 and 20-12-2018 and Iwant to detect the subsidence in my region through this period.Ido an interferogram with SRTM 1Sec Auto Download but the interferogram still blue,please help me.
Hello,Ihave two slc images at 20-12-2018and 19-2-2019,my area of study is syria and my data is IW-SLC, Iwant to detect the subsidence in my region through this period, but when Iam processing with phase unwrapping via SNAPHU ,the result was this.
