In other words, they must be in the same conditions of the S1A/B images and not in other subfolders. Also, be sure that you are not renaming the uncompressed folders containing the images.

You can just put your SLC images in the “SLC” folder as they are. When importing the data, SARPROZ will recognize them. Please check the training material on this website (Tutorials and Exercises) to become familiar with the basics of the tool!

a beta-version of the new downloader for the Sentinel-1 orbits is now implemented in the software.
In this version there are some know issues that will be fixed soon. In the meanwhile, please read below for the solutions:

ESA has replaced the repository for the Sentinel-1 orbit files. The new portal to download the orbit files can be visited here https://dataspace.copernicus.eu/

The new repository will be implemented in SARPROZ soon. In the meanwhile, you are kindly asked to download the files manually.

We think that some updates with respect to the previous post can be useful since more than 5 years have passed.

Q: What are the orbits used for Sentinel?

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.

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]

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]

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]

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]
