periz started the topic Sarproz Release 2016.10 in the forum Sarproz Forum 8 years, 6 months ago
Dear all,
a new Sarproz release is being uploaded at the time of writing.
Changes/new features:
– Time Series module. Beside some bug fixes and minor changes, you can now use this module for importing the time series generated from a different dataset. All what you need is: a) the export site par file (generated from the dataset selection window)…[Read more] -
periz replied to the topic APS – Ext. Dem Option in the forum Sarproz Forum 8 years, 6 months ago
Checking External DEM means removing a phase component proportional to what is written in the external DEM file.
So, this is not directly related to movement.
However, you estimate the movement from phase time series. If you remove or not remove a component from the phase values, clearly you are changing your data. As a consequence, the estimated…[Read more] -

Hi Nader,
yes, there are some residual fringes, when Yuxiao will have time he will improve his code.
In the meanwhile, as previously said, you can still process your data. There are several ways to remove or at least reduce spurious fringes.
The first thing to do is using the residual fringes estimation and removal module: did you do it?…[Read more] -

if you pick up manually a GCP,
you should not get significant problemshowever, just make sure not to have NaNs in the DEM in SAR coordinates
in case, place them to zero

periz replied to the topic Slave extraction: no images found in TIFF file in the forum Sarproz Forum 8 years, 6 months ago
Hi Ivana,
we are adding an option for visualizing which image has the problem.
I’ll send you the pcodes by email, there are also some other changes going on, keep it as a temporary version.
You’ll have to use the “debug” option in advanced parameters.
In that way, you can post here which is the image with problems, Yuxiao needs to look into it.
bye

Hi Sg,
– here http://sarproz.com/manual/slc_data_module.html you can read that you can update your dataset, trying to coregister again the failed images (be careful, when you press buttons always read carefully the messages given by the sw. in particular, if you do not check the “update” option you may overwrite your work if you press randomly…[Read more] -
periz replied to the topic Ramp in the forum Sarproz Forum 8 years, 6 months ago
hi Nader,
as mentioned by Yuxiao in a previous topic, there could be several reasons for having a ramp on an interferogram.
E.g. orbital inaccuracies, coregistration problems, atmospheric artifacts and so on.
Yuxiao is checking it because the Sentinel processing still deserves some extra care.
Generally speaking, forgetting for a moment that you…[Read more] -
periz replied to the topic DEM in the forum Sarproz Forum 8 years, 6 months ago
Hi Nader,
in your picture you can see 2 different types of NaNs (not-a-number):
a. some spots here and there (usually in areas of steep slopes): they correspond to SRTM missing data. Sarproz interpolates those values when the DEM in SAR coordinates is generated. You can check the result after your process it, by plotting it with the “view…[Read more] -

periz replied to the topic Sentinel-1 SLC IW intensity grayed out, corregistration not possible in the forum Sarproz Forum 8 years, 6 months ago
I do not know what you mean with “grayed out”.
I’d suggest to show you a comparison between a normal image and what you call a “grayed out” one.
Isn’t it that it was raining? Anyway, if problems, I guess they belong to the data, not to the extraction code…
About the examples you attached, the first 2 images look coregistrable but shifted.

Dora,
check the formatting of text files (end lines/carriage returns/tabs/…)
it may have been messed up by some operations (like ftp-ing files from linux to windows)

periz replied to the topic Atmospheric effect? in the forum Sarproz Forum 8 years, 6 months ago
Nader,
as a kind of general comment, with 6 images you should use a multi-master approach, and use also unwrapped interferograms. However, there are many comments more for your case, and also many options that could be chosen to help you solving your case. So, again, I suggest you to take a direct contact with some of us and have a remote session…[Read more]

Hi Nader,
when you get an error, zip the log and the lasterror.mat files and attach them together with your message.
From the very brief message visible in your attachment, it looks like one of the folders in the path of your data is containing spaces.
As previously said, you should learn the patience to go through the messages given by the…[Read more] -

Dear Nader,
here my comments:
1. yes we know that a complete manual is needed and we are working at that. in the meanwhile, please take seriously the available documentation. even if limited, it’s containing a lot of information and it takes time to be digested.
2. together with the documentation, you need to patiently read all the messages that…[Read more] -

periz replied to the topic select sub area Processing with sentinel TOPS data in the forum Sarproz Forum 8 years, 7 months ago
Hi Qingli,
is your area close to the borders of the footprint of Sentinel?
Check the footprint.kml and the masterarea.kml
what about the amplitude of ALL images?
You can check it either from the SLC data processing or by selecting the images one by one in the view parameters module - Load More
