Perhaps you can read the messages given by the software: why it is not working?

Dear dp,
How we can install new version! I tried use MANAGE VERSION but it doesn’t work.

Dear all,
a bug was found and fixed in the phase unwrapping code.
Moreover, a new option has been added: you can now load a mask to select on which pixels to apply phase unwrapping (in this way you can e.g. discard water bodies). To create a mask use the module “Custom Mask Generation” which takes a kml file as input.Tests and comments are most…[Read more]

hi Sandersax,
if you want to apply spatial phase unwrapping, please download the last sw version, a bug was found and fixed.

periz replied to the topic Subsidence in mm in the forum Sarproz Forum 8 years, 8 months ago
hi Sandersax,
to work on a single interferogram, use this module: http://sarproz.com/manual/insar_analysis_site.html
to see a description of insar parameters, check this http://sarproz.com/manual/insar_params.html
The idea is that, to convert the phase into mm, you have to unwrap the interferogram
so, if you check the “unwrap” option, then you can…[Read more] -

Hello everybody
Im a beginner in SARPROZ and subsidence topics, but I have to do a subsidence analysis for my thesis project.
I have a cuestion: how to convert the Phase results to displacement with SARPROZ?
I mean, I want displacement results in milimeters
but only I have the Phase.I attached my kml results
I hope someone of you can help…[Read more]

seppi-santiago replied to the topic APS – Ext. Dem Option in the forum Sarproz Forum 8 years, 8 months ago
Ok, I’ve visualized it and it is wrong, all zero values. The command prompt tells me this:
” wrong saturation values!” Must be NaN < Min < Max < NaN”
I reselected the DEM, I manually re-wrote the GCP and projected again the DEM amplitude in SAR coordinates. Still seeing all zeros in SAR coordinates.
What should I do?
Thanks,

“Site Processing”–>[Visulalization tools]–>”View Parameters”–>scroll the list to “Ext. DEM height”–>pick it–>Click “Plot”

Dan,
I’ve checked it with the DEM Visualization tool (screenshot attached), finding no NaNs, but according to the manual this displays the DEM in Geo coordinates, which file corresponds to the DEM in SAR coordinates?

Santiago,
you need to plot and check the DEM in SAR coordinates -
seppi-santiago replied to the topic APS – Ext. Dem Option in the forum Sarproz Forum 8 years, 8 months ago
I enclose my log file,
I remember that when you warned me about NaN values in my DEMI checked it and I converted them to zero.
When I made that correction I restarted the process again from the external DEM selection to make sure it was updated.Santiago

If it takes too long,
as I previously explained, it means that there is something wrong.
You did not include the log file, it seems the error is happening in a file that has been modified in the last version.
Anyway, by remotely sensing you case, I think your DEM is containing NaNs.
If you remember, I told you to check it, since your DEM is not…[Read more] -
