Pol-TomoSAR question consultation

qhwgis · July 22, 2020, 4:32pm

Dear all,
I am a newbie to PolSARpro software. I want to use UAVSAR data to complete some TomoSAR processing, but it has been unsuccessful.
The downloaded data includes 9 tracks of data:(https://uavsar.jpl.nasa.gov/cgi-bin/product.pl?jobName=bermsR_TM270_06#data)

But the import is still prompted like this:

What should I do with this?

Each dataset must be in a separate directory.
Please have a look here: Calibration in PolSARpro problem

Thank you very much for your answers. After reading the operating steps you gave, I tried to use UAVSAR data to do the same experiment and a new problem appeared. When I imported the data, the following problem appeared. Is it because my data was not downloaded properly? ? Looking forward to your answer, thank you!

This is the HH polarization data of the first track I downloaded:

Where did you download this data? The file names and structures don’t look familiar to me. I have only tested with UAVSAR from ASF.

Thanks again for your reply!
My data comes from (https://uavsar.jpl.nasa.gov/cgi-bin/product.pl?jobName=bermsR_TM270_06#data)

I have also tried to find UAVSAR data in ASF, and I can import grd data in PolSARpro, but I am not sure if this can be used for tomography. Because there seem to be only two data sets.

ABraun · July 23, 2020, 7:12am

hm, in this case ASF does not host all the data takes which are available.

There’s no way to retrieve the data from NASA at a different format?

qhwgis · July 23, 2020, 8:04am

Thank you very much! I just found a file in the grd format in NASA. This should be able to be imported, but can I use the data in this format to continue to do the tomographic processing according to the steps you gave before?This data seems to have been processed with multiple views.

ABraun · July 23, 2020, 8:25am

as long as it is complex, it is worth a try.

qhwgis · July 24, 2020, 2:23am

Thank you very much! I did the experiment with data in grd format, but according to the steps you gave before, the two data rows and column numbers are different when performing tomography. Is this a data problem? Is there any way to solve it? Looking forward to your answer!

maybe you first have to import them as Single products and use the coregistration to adjust all secondary products to the first one.

qhwgis · July 24, 2020, 6:34am

Uh, I have used “single data sets” to import every data, but I haven’t found a tool for registration, please help! thank you very much!

qhwgis · July 28, 2020, 2:06am

Hello, I imported a single data set separately and stored it in different folders. However, a new error appeared this time. What caused it?

ABraun · July 28, 2020, 4:23am

Did you mess up the order? First import, then extract.
According to your screenshot the data lies outside the folder which you selected for extraction. Please watch out for a clean data structure.

qhwgis · July 28, 2020, 6:50am

Hello, I did not change the storage location this time, but still such an error occurred! Could you please tell me how to solve this problem?

ABraun · July 28, 2020, 6:53am

could it be that the reason for this warning is that S2 matrix is required as input?
As you see in the screenshots of my example I extracted S2 and used the overall folder as “Main Input Directory”, noot the T3 subfolder.

qhwgis · July 28, 2020, 7:18am

Sorry, I did have a problem because I messed up the folder.I’m sorry to have caused you trouble.But now we have the problem of the number of rows and columns. What is the cause of this? I think it seems to be a problem with the data itself, don’t you? Looking forward to your reply!
