      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
      =====================================================================================================

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