By: mohseni1361 convert PALSAR1.0 by roipac to PALSAR1.1 [ reply ]   2010-Jul-08 06:11

I want to convert focuse slc of ALOS PALSAR1.1 to format ALOSPALSAR1.1 Eric Fielding told that ROI_pac is designed to work from raw data (L1.0 for PALSAR). It would require a fair amount of work to extract the metadata into a form you can use with ROI_pac. I hope some body did it,if somebody can please guide me how can I do it all the best mohseni.aref@gmail.com

You can process interferograms without a DEM by setting DEM=NULL in your int.proc file. ++Eric

Dear All, I am very new in this field but it sounds interesting to use PALSAR full polarimetric data for forest biophysical parameter estimation. I am trying PolInSAR for forest height estimation and using PolSAR pro software. but it seems very difficult. I would like to know your view in this field I am is anyone tried processing PALSAR full polarimetric 1.1 level data for forest parameter estimation like forest height, biomass, volume by using different types of polarimetric combination. Please share your code to process PALSAR 1.1 full Polarimetric data. Looking forward for your reply Thanking you With regards Ram

By: EJFielding RE: ALOS PALSAR 1.1 Full polarimetric data [ reply ]   2010-Apr-19 18:22

Dear Ram, The ROI_pac software is designed to work with the Level 1.0 PALSAR data. You can process the fully polarimetric PALSAR data by processing each channel separately. ++Eric

Dear All: Dose anyone know how to do the gain and offset compensation, and inteference remove for PALSAR 1.0 data with ROI PAC? Thank you!

By: EJFielding RE: PALSAR 1.0 gain and offset compensation etc. [ reply ]   2010-Apr-08 15:09

The make_raw_alos.pl script already sets up the I,Q bias information used by the rest of the processing. There is no radio frequency interference (RFI) removal program in ROI_pac. ++Eric

By: momo9317 How make_los.pl work? [ reply ]   2010-Mar-18 09:55

Dear All: Does anyone know how to make make_los.pl work? I am wondering that what does process_infile [xmin xmax ymin ymax] mean?

By: EJFielding RE: How make_los.pl work? [ reply ]   2010-Mar-25 16:43

The "make_los.pl" script uses the same int.proc file that you used to process the interferogram. You usually need to include the full path to the directories. ++Eric

By: espiritocz ALOS Palsar data L1.1 processing? [ reply ]   2010-Mar-12 04:19

Hi all. I am new to roi_pac. I try to use it as one of only few possibilities that I know that may help me processing my Alos Palsar data. Unfortunately, I dont know how (if) it can really help me with my case. The thing is that I own Alos Palsar L1.1 FBS data that is focused on actual Doppler values (not zero doppler, ESA...) - so, this way I am not able to coregister them correctly in, e.g. doris processor. Is there some way to use these images in roi_pac processing? The alos_preproc scripts are made only for L1.0 data... Thank you for ANY tips. Milan Lazecky

By: EJFielding RE: ALOS Palsar data L1.1 processing? [ reply ]   2010-Mar-12 13:25

There is more information at the ROI_pac Wiki: http://roipac.org/ /> ROI_pac is designed to work from raw data (L1.0 for PALSAR). For ALOS PALSAR, I do not know of anybody that has setup scripts to process the L1.1 data. It would require a fair amount of work to extract the metadata into a form you can use with ROI_pac. ++Eric

Hi, At http://roipac.org/Installation, step number 3: ../contrib/multitest.sh /full_path/roi_pac_testdir.tar /full_path/ROI_PAC_3_0_1/ROI_PAC/multibuild-071005-1506/installs/share/roi_pac /full_path/ROI_PAC_3_0_1/ROI_PAC/multibuild-071005-1506/installs/defaults/bin /full_path/ROI_PAC_3_0_1/ROI_PAC/multibuild-071005-1506/installs/gfortran/bin The last paths are one for the default binaries and another one for the gfortan which is supposed to be the compiler used during the compilation step. Include both as you have only written one (the default one). Good luck! Elena

By: EJFielding RE: ampcor killed during multitest.sh [ reply ]   2010-Mar-02 15:10

The "Killed" error usually means that the program wanted more memory resources than the machine has available. It looks like you are using a laptop, so I wonder if you have enough memory on the machine. I think the ROI_pac programs now need at least 1 GB of RAM available (not used by other programs). ++Eric

By: Abidalimirza RE: ampcor killed during multitest.sh [ reply ]   2010-Mar-11 19:42

Thanks a lot for your reply Eric. I actually am using Laptop but I dedicated 1GB of RAM using the u unlimited command. Do you still think the problem lies in limited memory? Thanks once again. Abid.

I have the same problem like you. Have you found a solution yet? Thank you.

By: caozhentan RE: ampcor killed during multitest.sh [ reply ]   2010-Jul-29 22:12

you should write the command ¡°ulimit -m unlimited¡±¡£I got the same problem with you£¬and had solved it¡£
