Re: satellite images (Insar)

Hello Smail, 

You can get Sentinel Data for free but I have not tried to process it with ADORE yet. After writing a small (~1 page) proposal you can also get access to ENVISAT and ERS archive which you can process with ADORE. 

Which software is best? That depends on your previous experience, if you have people using a particular software in your institution etc. If licensing is not a problem, I suggest ISCE (http://winsar.unavco.org/isce.html)  instead of Roi-Pac. I think ADORE-DORIS is slightly easier than DORIS but some see it as an extra layer of complication. I consider STAMPS in a different category, it is not a software you would like to use a single interferogram, but something to generate a series of interferograms and time series. If you look into GIAnT and would like to use it, ADORE-DORIS has it integrated, so it is somewhat easy to use. If you want to use STAMPS/time series, you will use it on its own... 

For installation help, I suggest the mailing lists for relevant software. ADORE-DORIS is relatively easy to install thanks to Antonio Valentino's packages on Ubuntu. It might not be the latest version though... You might need to run "check updates" in ADORE Doris after install. There is also a Ubuntu DVD that comes with ADORE DORIS pre-installed. 

I know ISCE has a VAGRANT installer, you might want to ask about that on their mailing list. 

What conditions for data selection? That depends where you are working (urban, rural), how fast/slow the expected deformation is, and what technique (PSI, or SBAS) you are planning to use. 

All the best, and welcome to ADORE-DORIS mailing list. 

batu.

Hello,

My name is SMAIL Tayeb and I’m a PHD student at the University of Blida, Algeria. and my fields of works are Civil engineering and Petroleum industry.

Now my researches are about the using of satellite images (Insar) to provide information about ground deformation, subsidence and uplift.. Etc. And I’d noticed that you have been working on this technique from some years and you have a good knowledge and experience.

So in order to complete and achieve my goals and dissertation I need advises and orientations from experts like you. So I hope you can offer me some helps.

First which Insar sensor can provides me a free data of my area of interest?

2^nd I want to know which software is the best for processing Insar image generation?

3^rd What are the conditions that should I follow to choose the appropriate data?

If you suggest some docs it will really nice from you.

I have - ROI_Pac,

           - Doris,

           - StaMPS.

     

softwares but they are very difficult to install them, I hope you help me to install and use the best.

Best regards,

SMAIL Tayeb
