        Is there any instruction somewhere on where and which files should be placed so that SarProz can find and read them?

            APS is long wave length signal. So 0.7 seems fine spatial distribution for aps. In sparse point protssesing u may use lower ASI 0.6 for exaple

                  DSF is DownSamplingFactor
                  Because APS is low frequency signal then the APS results will be multilooked in that factor

                      It is not to mutch information to tell exactly. if You have sentinel 1 images stack, You may use first Smart 5 option (remove thermal manualy). Then You will have data to analyse how big are the movements in AOI

                        Additionaly, I suggest to use Graph Analysis and Refinement module. It is between APS and SPP button. There is possible to remove low coherence connections and improve APS graph.

                          Ho big is Your bridge. If it is less than km You may skip APS and use small area module

                            I solved the problem myself.
                            the problem was in coregistration.

                            Firstly I used “only orbits” mode for coregistration.
                            After analyse of Site.log the program had gave warning to that in coregistration has some thing wrong.

                            I tried “Ampl Xcorr” mode for coregistration and it worked match better. No warnings, No Stripe

                            So in future I use “Ampl Xcorr” as default

                              You may set in module “Insar params” appropriate settings
                              Do not filter and multilook interferograms check “Flattening” and “DEM remove”
                              save settings
                              genereate interfereograms in module “interferograms protsessing”

                                I understood it now
                                Agree, that this is weird, but possible, way to illustrate direction.

                                  I don’t understand. Where is no such warning discribed in forum (I searched). And no lasterror.mat also because this is a warning not error
