    Hi Professor,

    How to import ALOS-2 SCANSAR data ?

    I have some PALSAR-2 level 1.1 data with 5 subswaths and HH Polarization in each data. I’m using SARProz in Ubuntu 16.04 LTS. When i want to get contents in SLC Data Processing, there are some errors so i can’t go through.

    Here are the error that i found in terminal :
    =====================================================================================================
    No directories found in /media/rajabun/Toshiba_1TB/ALOS2_F1_DinSAR/SLC/
    Analyzing files

    First identified file : /media/rajabun/Toshiba_1TB/ALOS2_F1_DinSAR/SLC/20160908.LED

    get_dir_slc : no known format recognized in directory /media/rajabun/Toshiba_1TB/ALOS2_F1_DinSAR/SLC/
    =====================================================================================================

    The format of some files are :
    =====================================================================================================
    1. IMG-HH-ALOS2123913750-160908-WBDR1.1__D-F1
    2. IMG-HH-ALOS2130123750-161020-WBDR1.1__D-F1

    3. LED-ALOS2123913750-160908-WBDR1.1__D
    4. LED-ALOS2130123750-161020-WBDR1.1__D

    5. TRL-HH-ALOS2123913750-160908-WBDR1.1__D
    6. TRL-HH-ALOS2130123750-161020-WBDR1.1__D

    7. VOL-HH-ALOS2123913750-160908-WBDR1.1__D
    8. VOL-HH-ALOS2130123750-161020-WBDR1.1__D
    =====================================================================================================
    I was tried to rename the first file and the third file to 20160908.SLC and 20160908.LED
    Then i was place it to SLC directory and it’s error.

    In my second experiment, i was tried to pre-processing it first with GMT5SAR and it produce :
    =====================================================================================================
    1. IMG-HH-ALOS2123913750-160908-WBDR1.1__D-F1.LED
    2. IMG-HH-ALOS2123913750-160908-WBDR1.1__D-F1.PRM
    3. IMG-HH-ALOS2123913750-160908-WBDR1.1__D-F1.SLC

    4. IMG-HH-ALOS2130123750-161020-WBDR1.1__D-F1.LED
    5. IMG-HH-ALOS2130123750-161020-WBDR1.1__D-F1.PRM
    6. IMG-HH-ALOS2130123750-161020-WBDR1.1__D-F1.SLC
    =====================================================================================================
    I was tried to rename the first file and the third file to 20160908.LED and 20160908.SLC
    Then i was place it to SLC directory and it’s error.

    What am i supposed to do ?
    Thank you, Professor

    inside the SLC folder
    you should have a directory for each image
    each directory should contain all original files (img, led, trl …)
