SARPROZ ©

The software has some default parameters for coregistration.
If the coregistration fails at the first step, one has to plot the images to check why it failed.
Then, depending on the reason, you can change the coregistration parameters.

In your case, the two images look similar and have corresponding features that can be used for coregistering…[Read more]

a. before exporting data, I suggest you to use the “visualization tools” to explore the results. In particular, histograms and scatter plots are very useful tools. In the scatter plots, you can analyze the correlation between different parameters, you can plot them in 2D/3D in SAR coordinates or geographic coordinates, you can place many…[Read more]

Hi Fatma,
I moved your post to a new topic, because it’s dealing with an important matter.
Sarproz has been designed to recover from almost any situation.
You should NEVER need to start processing things over again.
In particular, for interferogram processing, in InSAR Params (section 1.4.3.1. of the manual) you can tick the “update”
option and…[Read more]

Hi Qingli.

APS processing module options:
– I.P. stays for Inverted Parameters
– I.R. Inverted Residuals
– Tri. I.R. Triangular Inverted Residuals
Generally, you should use the I.R. option. If the APS looks ok and the test shows a homogeneous high coherence in your analyzed area, then you can proceed further and be assured that everything is…[Read more]

Hi Fatma,

there are many messages in your log:
a. failed to connect to askgeo.com! This means that weather data have not been downloaded. You can do it manually later (from the dataset selection window). By the way, Yuxiao just updated this code, it will be more efficient in a future Sarproz release.
b. WARNING probably the shift is too large.…[Read more]

Hi Shweta.
Firstly, apologies to the forum members for spamming their email folders.
Let’s see if the jpg I am attaching is going to work.

About your questions:
a. if you get errors, you have to send me the lasterror.mat and the log file. Anyway, here the last version of pcodes (which may have solved your matter): http://we.tl/bw8etoJaqY
b. not…[Read more]

test again

I suggest you to go through the tutorials and exercises section in this website.
To export your data in google earth, you should use the extended geocoding function.
Please be aware that, if you import SLC data, the software gives you all the tools for area selection, visualization and so on.
If you import RSLC data, the assumption is that you…[Read more]

NO
If you want to ” re-extract and co-register” you need original SLC data.
If you want to choose a different master among your images (no re-extraction co-registration) you can do it via “Dataset selection”.
If you want to extract a new (smaller area) dataset from the current one, use “sub-dataset extraction”.

Sarproz usually chooses the Master…[Read more]

If you are importing data which have already been extracted and co-registered by Gamma, then there is no need any more to extract and co-register them again… Not only: since you do not have original SLC data, the SLC data module cannot work… The software is right in telling you that no data is found (if you would be importing SLC data, you…[Read more]

I need to see the log file and the lasterror.mat. Anyway, check your file permissions in the directory where Sarproz is installed and also in the data directory. Usually, when you launch it, Sarproz checks if you have write permissions and it returns a warning message if anything wrong is found…
