seppi-santiago started the topic Parameters Range in the forum Sarproz Forum 9 years, 4 months ago
Hello,
I’ve got a number of GPS measurement for a set of Corner Reflectors which are identified as PS within SarProz.
When looking at the GPS measurements, projected into LOS, the displacement velocity ranges in general from 0 to -500 mm/yr, except for 1 point where that reaches almost -1000 mm/yr.
The question is, is it ok to input this -1000…[Read more]

DSF is the downsampling factor of the final APS. R is the length of the correlation filter (pixels).

Hello,
The R and DSF parameters stand for stratified APS processing? what do they mean and how are they used?Thanks,
Santiago

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 9 years, 4 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 9 years, 4 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,
