Hi all, sorry if this message is out of topics. Does anybody compiled mdx under Mac OS X snow leopard 10.6 ? thanks NIcola

Hello All! My file ampmag.off and ampmag_cull.off have size 0. from this cull.out has size 0. What information have this files? How is it possible to decide this problem? Best, Selena

By: yaoganyingjie DOPPLER CENTROID ESTIMATION [ reply ]   2009-Dec-17 12:56

It seems that the doppler centroid estimation program in ROI_PAC can not precisely estimate the true value, because the estimated values show relative large fluctuations in the range direction, as we can see by dipicting them in xmgrace. Will this problem further seriously affect the focusing and resultantly affect the coregistration between master and slave image? I do not have much experience. Is there anyone who can answer me?

By: momo9317 How to re-wrap the unwrapped image? [ reply ]   2009-Dec-07 08:29

Dear All: Does anyone know how to re-wrap the unwrapped image? Thank you

By: goudarzi612 RE: How to re-wrap the unwrapped image? [ reply ]   2009-Dec-07 08:54

I have developed a code in GMT and csh that converts back modeled unwrapped interferograms to the wrapped ones. I use the code for results of inversion problem. I can share it with you. Send me an email: ma_goudarzi at yahoo dot com Regards

By: yaobinsheng RE: How to re-wrap the unwrapped image? [ reply ]   2010-Jan-18 23:13

Dear momo, I am suffering the same problem as you posted in this forum when i processed one pair of PALSAR images. It is about the add_rmg script. How did you fix this problem? Expect for your reply or you can send me email: yaobinsheng@gmail dot com Thanks in advance!

By: Lian About add_rmgAmpPhs.pl [ reply ]   2009-Nov-10 11:00

Dear all: When I use the snaphu_mask.pl to do the unwrap. This calls add_rmgAmpPhs.pl. When I run the add_rmAmpPhs.pl, there was no error report. However, the outfile of add_rmAmpPhs.pl is nothing. Dose anyone have an idea about this probllem? Thanks~

By: goudarzi612 Order of scenes [ reply ]   2009-Oct-02 04:15

Hi everyone I have a pair of ALOS PALSAR images for earthquake of 12th april 2009 in Laquila, Italy acquired at 080703 and 090521. I can process them when the post seismic image is the second image in proc file (080703_090521 order). But this order gives me uplift instead of subsidence. When I change the order of scenes, i.e. when the post seismic image is the first one (090521_080703), then about 50% of the image can be correlated and then the result is quite crap in this 50% part. Does any one have an idea about this? Thanks Ali

By: EJFielding RE: Order of scenes [ reply ]   2009-Oct-02 10:11

I normally process the images with the "before" scene as the master or first scene. This does result in phase in the .unw file that is the negative of the range change, but it is easy to multiply the phase by -1 in any post processing steps. It sounds like your processing in with the "after" scene as the master scene is not doing the "ampcor" offsets correctly. I do not know why. ++Eric

By: goudarzi612 RE: Order of scenes [ reply ]   2009-Oct-03 05:52

when I draw contents of dop.out files in date1 and date2 directories, they have almost same pattern, except at the beginning of one of the scenes in which some intense fluctuations are seen. I think it is the reason for poor co-registration just in one side of the image pair which leads to decorrelation only on that part. Also DOPPLER_RANGE0s are quite close together. So, is there any solution, some thing like sub-setting or masking, to exclude those inflectuations input images? Thank you Ali

ALOS data of Sichuan earthquake is opened on free? really? then where can i find it? recommend me, please!!

By: Lian About snaphu in roi_pac [ reply ]   2009-Sep-15 21:54

Dear all: I want to use the option "unw_method=snaphu" to do the unwrap,should I use process_2pass_master.pl instead of process_2pass.pl? When I process with"process_2pass_master.pl *.proc filtered unwrapped", meet this problems:"snaphu_mask.pl cannot find add_rmgAmpPhs". I find that there is no "add_rmgAmpPhs" file in the INT_BIN folder. Should I compile the add_rmgAmpPhs.c manually? But if I compile "gcc -o add_rmgAmpPhs add_rmgAmpPhs", I still meet the problem "snaphu -f filt_*.snaphuconf -v > filt_*.snaphuout 2> filt_*.snaphuerr", I don"t know how to fix this problem. Does anyone know how to fix this problem? Any advice would by appreciated.

By: EJFielding RE: About snaphu in roi_pac [ reply ]   2009-Sep-16 17:34

It seems that the 3.0.1 release is not complete for running "snaphu". It is not easy to compile and install the required programs to fix the problem. We will probably do a new release soon that fixes these problems. ++Eric

By: Lian RE: About snaphu in roi_pac [ reply ]   2009-Sep-16 20:49

Thanks very much! I am looking forword this new release.

By: EJFielding RE: About snaphu in roi_pac [ reply ]   2009-Sep-19 02:03

I posted instructions on how to fix this missing program on the Wiki. http://roipac.org/Patches You can just copy the executable to your $INT_BIN. ++Eric

By: Lian RE: About snaphu in roi_pac [ reply ]   2009-Nov-10 10:48

Thank you very much~~ I have fixed the problem following your instructions. Moreover, the error "snaphu -f *.snaphuconf -v 1> *.snaphuout 2> *.snaphuerr" seems that the parameter "LOGFILE *.snaphulog" which in the *.snaphuconf causes the fail. I constructed *.snaphuconf without the parameter "LOGFILE *.snaphulog". It fixed the error. But I do not know why?

By: bhchoe99 wher can i find the ALOS orbit data? [ reply ]   2009-Sep-08 05:49

i have been finding ALOS orbit data file. but i can find it it is necessary for process2pass? give me a advice..please

By: EJFielding RE: wher can i find the ALOS orbit data? [ reply ]   2009-Sep-14 15:54

The ALOS PALSAR orbit data is contained in the LED- file that comes with the IMG- data file. You do not need a separate ALOS orbit data file. ++Eric

Dear All, I work as support to ESA EO R&D Section and I will attend the ROI_PAC Short Course in Naples (Dr. Sansosti, Dr.Borgstrom and Dr. Fielding are in charge of it)so I need to install in my laptop the software ( and also the MDX tool which I have already requested to JPL) for this educational purpose. I just submitt my second request ( I did not get new from the previous one ..hope it is not lost) and i got this message: Request ROI_PAC Order # 28568 processed An email with download instructions has been sent to the email address you entered. Thank you for your interest in the Open Channel Foundation! But I did not receive any email from you. I hope it will be possible to speed up my request given that the course will start il less than 2 weeks and I would like to familiarize a little with ROI_PAC . For any comunication i left my work-email my personal one is rafrigraz@yahoo.it .Hope to get soon your news. Best regards.Raffale

Dear Raffale, Please check your "junk mail" folder to see if the message from Open Channel was incorrectly classified as junk. If you still have trouble, contact <webmaster@openchannelsoftware.org>; for more assistance.

Dear Eric, Thank you very much for your advice. I wrote them and they already solved my problem. With kind regards. Raffaele
