Hello,
I’m trying to coregister two images relevant to
S1A_IW_SLC__1SDV_20180108T165715_20180108T165742_020066_022322_6EFC.SAFE
S1A_IW_SLC__1SDV_20181222T165722_20181222T165749_025141_02C6C5_F283.SAFE
i have executed all the step described in the tutorial HAZA03_Land-Subsidence_Mexico-city.pdf as reference considering VV band IW3 burst and 1 to 4 burst.
I’m not sure the results of the coregistration is ok.
Here attached the picture result of coregistration where i think to see not overlapping areas.
Furthermore attached the final result.
Thank you for your suggstions.
The coherence is very low outside urban (I presume) areas due to the very long temporal baseline of almost a year. Co-registration is probably ok.
Thank you Mengdahl, so i can presume that those results, at least in more coherent areas, are correct.
I’m checking my results with those of Europeang Ground Motion service on the same period.
The area of interest (a portion of that in the image) is subject to slow subsidence (1.5 cm per year) so my idea was to see subsidence effect on an year time window also reducing vegetation difference thanks to the similar season.
I will keep you updated.
