periz replied to the topic DEM export in the forum Sarproz Forum 9 years, 3 months ago
Question for you and for all geotiff users:
is anybody needing an RGB DEM?
Or can I switch the system to automatically (and always) output geotiff DEM files in “black and white”?
After getting a feedback on this, I just need to change 1 line…
thx

hi Yuyu,
as you can read in the sw specifications, sarproz accept SLC data as inputs, that is, focused data.
Level 1.0 is raw data, and it cannot be imported.
You can either order again your data, asking for level 1.1 (SLC or focused) or use an other software to focus it (as roi-pac)

periz replied to the topic DEM correction in the forum Sarproz Forum 9 years, 3 months ago
Hi Milan,
the key question is: in which format is your DEM?
if it’s geotiff, nothing to do (unless you find the way to re-write the geotiff).
The sw reads the fill-in boxes only if you are loading a matrix in gamma-format (read the manual).
In that case, changing the lat-lon coordinates has the wished effect.To understand the error message you…[Read more]

Hi PY,
my suggestion would be first of all to look at interferograms.
case A. you have no coherence. Then the question is: is it on the mountains?
case A1. yes it’s on the mountains. Then download the last sw version and use the DEM-dependent coregistration refinement. This module requires a well aligned DEM. And it still needs some optimization…[Read more] -

Dear Prof DP
I was wondering if SARPROZ could export insarDEM into DEM geotiff file.
It seems the file I have exported was a image (RGB) tiff, not a DEM geotiff .

Dear Prof
The PALSAR data I got is .0_A. When I put the dataset in the folder of SLC, SARPROZ cannot read this file.
Any suggestion? Is there any data conversion required?
ThanksYUYU

Hi,
I use external DEM but it is shifted. I found out the correction coefficients in WGS-84 (shift is cca 0.025°N and -0.1°E) and used them to correct the Corner Lat/Lon boxes in “External DEM selection”.
After this change I have remade External DEM and synthetic amplitude in SAR coordinates. But nothing changed. The obvious shift is still p…[Read more] -

Dear all, Daniele,
2 weeks ago, a large underground quarry (near the surface) collapsed.
I have already processed the area with a standard PS approach using ERS and ENVISAT data to see if something was already happening in the past.
But as it is a field area, I have not any PS in my results.Any suggestions? How does Quasi-PS works?
Thanks for…[Read more]

Dear Ana,
Indeed the area should be larger – don’t worry to extend it. To check the small area (after you prepare project using bigger area), there is special Toolbox in Sarproz called Small Area Processing. It works very well!

download the last pcodes (through the “manage version” module), I included a version check and an automatic choice between flip and flipdim

cnu_lee replied to the topic "set orbits" error in the forum Sarproz Forum 9 years, 4 months ago
You mean I should rename the MATLAB system function file “flipdim”?
But I found three flipdim.m files in MATLAB, which one should I choose?
-
periz replied to the topic "set orbits" error in the forum Sarproz Forum 9 years, 4 months ago
this is a new matlab function: flip.
if you get an error, it means u do not have it, that is, u have an older matlab
I’ll insert a simple version check.
U can quickly solve it by copying and renaming the function “flipdim” to “flip” -

Thank you,professor.
I download a new version instead of the old one and the problem has been solved. But another problem is coming when I clicked “master extraction”…
THis zip file included lasterror.mat and log file

periz replied to the topic "set orbits" error in the forum Sarproz Forum 9 years, 4 months ago
IMPORTANT NOTE:
to upload mat and log files, please zip them.
Without them I cannot track the error
Anyway, I guess that you did not download the last sw version, did you?
To do so, use the “manage version” module.
I think that that error was a temporarily caused by a sw update and it was already fixed…

periz replied to the topic discard small area processing in the forum Sarproz Forum 9 years, 4 months ago
Hi Ana,
the size you have chosen is even smaller than the (default) reference window used for the coregistration (64 pixels as you can see in the coregistration parameters).
Maybe if you make those numbers match it will work (I never tested the smaller possible area to coregister).
Usually, even for test or educational purposes, we take bigger…[Read more] -

Hi,Professor Daniele,
During the Radarsat-2 images were imported , in the “SLC DATA processing” module, after I clicked the “set orbits”,there was always an error occuring so that process couldn’t continue.
I uploaded the “lasterror.mat” file and log file.
Hope your reply!
Thanks! -

Dear Prof.Daniele
I have some problem for small area processing. I use 20 ASAR image. If I choose interest area and try processing for co-registration, the matlab comment show me message that my area too small to match.
And how is minimum area can be processed by SARPROZ software?
Please find attach file below.Best Regards,

Dear gypsophila1 – please, if you have question, use Forum -> Create new topic, instead of “post update”. And the problem is that you should first make some “new project folder”, for example /media/Seagate/Radarsat-2_Processing and there you should link your /media/Seagate/Radarsat-2/SLC folder (do you use linux or windows?) – and in Sarproz when…[Read more]
