You can choose any parameter for your reference selection: temporal or spatial coherence, amplitude stability index, reflectivity map or whatever.
Or you can even pick it up manually (ticking the corresponding box) depending on other infos/observations (e.g. you want it on the ground, in a stable area or whatever).
InSAR is a differential…[Read more] -

Hi
I’ll appreciate you if answer my question:
Which parameters should i choose in “small area processing > multi image analysis” module where is located in “reference point” section? And why the results varies with choosing different parameters of reference point?Thanks and best regards

Hi! I followed all the instructions but I cannot import S1A data.
I put the zipped folders, ended in “.SAFE” inside the SLC folder. The SLC folder is inside a folder called TEST:

Dear all,
since a few days Sarproz is experiencing failures in downloading SRTM files. The issue is caused by some SSL protocol changes on the USGS site. While we work at a solution, please consider that SRTM data is currently forced to zero by the software. To overcome the problem, manually download the files from here:…[Read more] -

Yes, I tried both, estimation of relative shifts (offsets) and estimation of AD pairs. And I used AD pairs and grid but also in this case are my outputs the smame.

Dear SarProz developer;
I have successfully processed a single interferogram. however, i have a problem regarding export it to a GeoTIFF 32 image.
I have attached lasterror.mat, and 31_Aug_2017_16_14_35_sarproz.log files, please let me know what is the problem in my procedure.

periz replied to the topic Decomposition LOS to E-W and UP-DOWN in the forum Sarproz Forum 6 years, 12 months ago
Did you do process the 2 clouds of points?
1- estimation of relative shifts (offsets)
2- estimation of AD pairs
here a brief description
http://sarproz.com/manual/multi_sens.html
After having estimated those 2 things, you can plot vertical and horizontal components either on AD pairs or on a grid (not on the original points)
in the future we will…[Read more] -

Hello,
I try to use SARPROZ for decomposition deformations in LOS to deformations in E-W and UP-DOWN. I have two dataset – ascending and descending (data from Sentinel-1A, Sentinel-1B).
I did the following:
1. I have exported time series in “Sparse Points processing” (for ASC and DSC data). I have exported time series like .tsobj files.

periz replied to the topic Reflectivity Min and Max values and units in the forum Sarproz Forum 7 years ago
The reflectivity map is the average amplitude of all images.
The amplitude is measured in volts.
Values there are the output of a normalization.
Usually amplitude is plotted between 0 and 3, you can change the upper value in the advanced parameters http://sarproz.com/manual/adv_param.html
The actual maximum value depends on the strongest scatterer…[Read more] -
