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)

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.

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 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

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?

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

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…

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]

The files couldn’t be uploaded.The error was
Undefined variable “p_orbit” or class “p_orbit.coef_pos.x”.

Dear Prof.Daniele

I just solve my problem. Now, I can understand why the SAR image (Refl.map) like that.
Thanks very much

Best Regards,

Ana
