Good morning Yunus,
from my experience, at the moment I do the same, i.e. using the multi-sense module or external GIS-based tools to produce the maps of Vertical/EW motion with some spatial averaging.About the time series, what I do is to apply use the same formula used to derive the maps applied to some specific points, manually.
The…[Read more]

alpetrucci replied to the topic How to select a same reference point for different projects in the forum Sarproz Forum 4 years, 6 months ago
Hi Bridgetwang.
If you create 3 different projects, it means that you are going to use 3 different Master images for the Coregistration step. For this reason, the final matrix of the coregistered images, such as all the parameters like the reflectivity map and other data will be very similiar but not identical. This is also true for the…[Read more]

alpetrucci replied to the topic understanding aps estimations parameters and results in the forum Sarproz Forum 4 years, 8 months ago
Hi Mehrnoosh,
usually, the best approach is to keep a quite large set of range taking into account the expected values by considering:
– the characteristics of your AOI (e.g. presence of high rise buildings);
– the type of graph you created (long connections, short connections, etc. )Once you have a preliminary estimation, you can have a look…[Read more]

alfredo_rocca replied to the topic master extraction with sentinel-1 images in the forum Sarproz Forum 8 years ago
Hi Yasser,
the APS module, is the “core” of the multi-image InSAR process (say PS, QPS analyses). As you probably know, to extract as more information as possible from your dataset, all images need to have the same technical features (resolution, incidence angle, polarization, etc.).
Also the number of images is very important. If you have only…[Read more]

alfredo_rocca replied to the topic APS estimation in the forum Sarproz Forum 8 years, 7 months ago
Hi Anarizka,
1) Here my personal suggestion about your first question. The best way to understand the goodness of your results (both preliminary and final) is based on the knowledge about the process you are investigating. You should address your specific case study (landslide? subsidence? localised structural issues?) being driven by a general…[Read more]
