I took two points spatially close (ca 200m distance). Because the area per se have not so many points.
Unfortunately, I do not know anyone close that can help me. I am doing this project basically from zero.
But ok thanks I will try to improve the resolution then -

Let’s see. In the figure attached , there is the East -West velocities from the module. Blue is positive so East. So far so good.
But I took one descending point which has final trend of -20mm/year (the “typical” value you get in the small area processing), and one ascending point value of -7mm/year. So both negative.
The points are located in a…[Read more] -

Yes in my case, if A is + and D is – then the resultant is negative (toward West). Yes I have no doubts about the sign per se, but about the fact that the software and my computation do not agree (on a determined location, software says + and my computation says -). Is this what I cannot figure out. I check the formulas many times and always got…[Read more]

Hello,
so I used the software (multi sensor module) to do the combination of ascending and descending to get horizontal and vertical velocities. And, since I was interested to see the horizontal deformation along time, I took the values in the time series and I used the formula found in the paper “Space geodetic monitoring of engineered…[Read more] -

Hello sorry, again me making questions:
which are the formula used by this software to make the projections in the horizontal and vertical direction?
If it is possible to know of coursecheers

Hello,
I got maybe a stupid question but I got suddenly unsure.
So when in Geocoding (Small processing) I click on “Data series” I get the time series of the point but, please correct me:
-if I do not tick anything I get the residues phase, which is the phase minus the topographic and the movement component
-if I tick “mov” I add the movement…[Read more] -

Lovely!!
Thank you very much! -

Hello everyone,
After importing and coregistering the images, I started the preliminary analysis.
I am trying to calculate the reflectivity map in the Site Processing.
I get this message :Undefined function or variable ‘S’
Even after this message, apparently Matlab recognizes that it was calculated because then the box becomes green. But if I…[Read more]

Thanks very much for the explanation.
Although, I have not really understood what I should do in practice (sorry, for me is a quite new world…and software).
I process the two datasets using Site Processing and then..? I use the multi sensor analysis module? Or I need to do something else in the middle?
Thanks for the infinite patience -
ceciliabo replied to the topic Combine different geometries for decomposition of LOS motion? in the forum Sarproz Forum 7 years, 3 months ago
Also, what happens if the PS points are not coincident in the two datasets?

ceciliabo replied to the topic Combine different geometries for decomposition of LOS motion? in the forum Sarproz Forum 7 years, 3 months ago
Thanks for the super quick answer.
Yes I get a little bit lost in the export part. So I process the sets separately (and here all clear). About the export..I am working with a small area, so with Small Area Processing. So what I have to do is “just” click export the time series in the geocoding window, and then the software will recognize…[Read more] -

Hello,
I have two datasets of Sentinel images (one ascending and one descending). I would like to know if it is possible through the software to decompose the LOS motion in vertical and horizontal components.
Or simply, I have to process the two datasets separetely and then apply some formula using the LOS values? In that case, which…[Read more] -

Hello!
So this is the link of the files, and hopefully it works. If you need something else, please do not esitate.thanks

Hello, thanks for the answer. Now I tried changing master (20160603), choosing one with better condition. The area is the maximum common, in order to avoid problems. Some of the images are coregisterred, some are not (18 failed out 51 slaves).
A series of warnings appear, including one that says “Reference to non-existent field ‘ra’.”.
The major…[Read more] -

Hello,
yes well the area that i cropped has a radius of 12km so I thought it would have been ok. I tried to change the master, but still the same. I cannot plot the images because it actually does not the coregistration. I can only see the master and the slave images one by one.
Anyway here there is the log file. -

Hello,
I am super new in using this software. I am processing 29 Sentinel 1 TOPS SLC images. My aim is the deformation of a dam (so quite small area). So first of all data selection. Footprints are ok, in Google Earth everything seems fine. First thing that I noticed is at the moment of Master extraction I get “28 slave images have not been…[Read more] -
