You are using the Sparse LS unwrapping algorithm. Probably you are using all available memory.
Please use the Task Manager windows application to see if you used all memory and/or if the Sarproz main application is running or not.
if you have resources issue, multilook your interferograms to save memory

hi prof,

understood. tqvm

Hello
I got a problem !!
On site processing
In the «InSAR processing»
In the «Interferogram processing»

It only goes up to 25% and will not change !!

thanks

In the attachment you see the difference between calculating the cum disp from the data or from the model (the drawing is made by hands, but the concept is that the smart filter results in a smoothing of the data).
We have chosen to calculate the cumulative displacement from the model. It’s a choice, that does not mean it’s the truth.
If you want…[Read more]

hello prof,

i have almost similar question. i used Smart5 with Small Temporal Baseline image graph on 6 images (which is less than u suggested for its robustness; in message #3231) to detect subsidence

obtained results from 2 weeks baselines are:
weeks: 0 2 4 6 8 12

Def. trend = deformation trend [mm/year] (or velocity or annual rate)
Cum. disp. = cumulative displacement [mm] (it’s the displacement at the end of the time series minus the displacement at the beginning. it’s calculated on the model, neglecting possible residual -not modeled- displacement)

The colored dots in your picture show the deformation…[Read more]

Hi David,
in that plot you can see the red point indicating the location of the pixel you are observing
the blue line is a line connecting the satellite with the ground point
the black line is the local ground profile taken from the DEM you loaded (SRTM by default).
In principle, this is what is plotted, independently from whether it is true or…[Read more]

Hi Mohsen,
thank you for your question

The tool automatically downloads SRTM files from internet

If anything fails, a message is printed but the tool
does not stop running

If a SRTM file is not found, it is created and filled with zeros

To re-download a file that was filled with zeros, delete it (the software will warn you if a
file filled…[Read more]

Thank you very much! I’ll try as you recommended 🙂

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]

zoom in, you will see it’s sparse

hello,

why is my sparse points are not sparse but most likely are densed? im following the tutorial for InSAR Time-Series – Land Subsidence. TQ
