Hi,

I followed your instructions and it worked. Yes, the files were focused by the NASA ASF, and I mistakenly thought that were focused with ROI_PAC.

Thank you everyone for your help.

Yes, these ALOS PALSAR files must have come from the NASA Alaska Satellite Facility DAAC. They use the standard JAXA processing software. Only the outer zip or tar needs to be unpacked and the “product” folder entered to get the JAXA product format.

Hello Janbu,

You have the ALOS SLC files there already. You don’t need to rename anything. Please follow the advice periz offered above and it should work. You can let us know how it goes.

Q

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]

ok

please attach the file E:SARPROZ_2tsxsite.log

Dear Periz,thanks for your support.

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

hi
and, What is the name of the folder for each ASAR image in slc directory?
for example:
” ASA_IMS_1PNUPA20050614_064342_000000162038_00106_17194_5808.N1 ”
Is this name correct? What is the correct format?
Thank you sooner

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]

3. if the cumulative displacement CumDisp.mat file is not there, it means it was not saved. Is the velocity there? If the velocity is there and the cumulative displacement not, it means you estimated a linear model, so, the cumulative displacement was not produced. To know to cumulative displacement, just multiply the velocity by the observation…[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]
