Hi,
Sorry that I missed a detail in your attached picture.
I see that you’re using two sensors.
If you want to do this, did you follow this instructions?
“The software has also the possibility of processing two sensors together (as ERS and Envisat. See References).
To do this, you need to create another folder within the DataSet directory.…[Read more] -

Dear Yuxiao, The name of the asar file i am trying to import is “ASA_IMS_1PNUPA20100621_045425_000000162090_00291_43431_6800”.
Can you please suggest me that, is there any way to convert this file to IMS or APS? -
Yuxiao replied to the topic IMPORTING THE ENVISAT ASAR DATA in the forum Sarproz Forum 9 years, 6 months ago
It simply means your data is not supported, it is not IMS or APS data
Look into the name of your N1 data, and you will know what it is
or you can post the name here so we can know what type it is

periz replied to the topic Error in coregistration step with ALOS data in the forum Sarproz Forum 9 years, 6 months ago
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]

admin replied to the topic SARProz results analysis in the forum Sarproz Forum 9 years, 7 months ago
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]

admin started the topic Persistent Scatterers steps and interferograms generation in the forum Sarproz Forum 9 years, 7 months ago
While waiting for more documentation to come,
I open a new topic on this matter for the newcomers.
In Sarproz, Persistent Scatterers interferometry is applied to un-filtered full-resolution data.
This means that you do not need to generate interferograms if you want to process Persistent Scatterers.
It is suggested to process interferograms if…[Read more] -
admin replied to the topic Recovery of operations in the forum Sarproz Forum 9 years, 7 months ago
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] -

Dear dan,
Thanks for the excellent software.
The new version for SARPROZ is much more convenient than the previous one.
however, i have some quesitons about the processing.
1. in APS options group under APS processing, there are several options for it, including I.P., I.R., Tri.I.R. and stratif.
For APS processing, is there any basic idea to…[Read more] -
