Dear, Sumaya Mn

First I want to advice you to use optical remote sensing for change detection cause althouh, Radar remote sensing can achieve better detection result with a high detection rate and alow false-alarm rate in Synthetic Aperture Radar (SAR) images but they are having some more difficulties than optical ones due to the fact that SAR images suffer from the presence of the speckle noise and also SAR images processing more complex, you must have computer with memory higher then 12 GB .

Thanks Shaheen, i am interested in working with both optical and SAR images. Thanks Alvioli for providing links to get datas.

But i would like to get projects from remote sensing labs and from other centres. I am very much interested in doing projects which will be collaborated with the research lab. In order to receive projects, How to approach them. If anybody knows how to reach out, kindly share.

Thanks & Regards,

M.N.Sumaiya.

You can use ALOS Palsar data from Alaska

Sentinel data from ESA

So I recommended SNAP toolbox
