Hi Janbu,
I do not know myself the Doris/Roi-Pac formats, we should wait for an advice from someone else. But the files you attached above look like coming directly from the data provider (or at least they look like in the same format). So, try the following: untar you file in a sub-directory (like “D26075_1_A3_26420”) inside the SLC folder and…[Read more]

please attach the file E:SARPROZ_2tsxsite.log

to detect ASAR images, Sarproz searches for ASA_… files. they can be in subdirectories or all in the SLC folder

To get assistance, please attach log and lasterror.mat files

yes, it’s a measure of the accuracy of the height estimation
it is calculated based on the distribution of the dataset parameters (normal and temporal baselines) and on the options you selected to estimate the time series parameters (as velocity and height)

Yes, velocity and deformation trends are the same.
The cumulative displacement is saved when you do a non-linear processing.
You do a non-linear processing if you input a value in the “smart” box in the time series processing options.
That value corresponds to the length of a temporal filter. So, the outcome is a non-parametric estimation of the…[Read more]

1. select a set of points via load mask using e.g. the temporal coherence or the amplitude stability index. it does not make any sense to select points based on cumulative displacement

2. then check your results via histogram and scatter plots modules. you can check the histogram of the cumulative displacement to understand what is wrong. then…[Read more]

Use this module: http://sarproz.com/manual/xplot.html
1. load points via load mask in site processing
2. open the scatter plots module
3. choose latitude as y axis, longitude as x axis, velocity or any other parameter of interest as color
4. press “go” in filter/matrix visualization to check what you are doing
5. press “geoout” in the same frame…[Read more]

Looks like we overlooked your post…
Did you solve the issue?
You don’t need to increase the search pixel: the initial cross-correlation is used to estimate and remove the big shifts. Increase the search pixel only if you think that shifts change significantly within the image (e.g. because of a huge stretch).
We cannot debug your lasterror…[Read more]

that’s exactly the purpose of using a GCP. Anyway in Sarproz you can correct such shifts also later with the geographic corrections module

I don’t see easily a reason for that residual ramp. This would deserve some deeper investigation. The results anyway are now much better.
About the geocoded reflectivity map: are you keeping a 1×1 downsampling? Otherwise, u’ll degrade the resolution. The mean kml generated from the GCP module is downsampled 8×8. That map is generated just to give…[Read more]

hi qingli please zip and attach mat and log files

Hi Venera,
1. update your software version: it’s old. An example: selecting asymmetric ranges of values in the APS module is wrong, now the sw does not allow you anymore to choose that
2. The Auto Graph works very well in urban areas to select flower centers on the ground. However, I don’t think it’s a good choice in your case. simply use a…[Read more]

Yuxiao will contact you to get more infos on the case.

Try to see if updating the sw solves the problem (via manage version)

You should attach this log: H:kwekwesite.log, the one you sent is empty.
And the lasterror.mat is not corresponding to the error you reported above: lasterror.mat files are overwritten if multiple errors occur. To avoid loosing them you can insert your email address in the advanced parameters: you will receive an email for each error, with log…[Read more]

please zip the two files and attach the .zip file
