Hi, I want to extract all pixel information of a SAR image in a single file. Are there any tools present in SNAP? I tried Raster->Export->Extract Pixel Value. But it did not work. is it possible to extract all present pixel information present in entire SAR image? Or I have to take help of any other software or language?
Do you mean that you want all the pixels in a single file, for example a GeoTIFF?
Yes sir, It can be a docx file or text file or any other file format and don’t want to lose any information. All I just want to read that pixel information from a python code with the help of that exported pixel info file.
You can use File / Export / CSV. This will create a text file with the data you want.
But be careful the file might get huge. Several GB.
You can also draw a shape on the image and then right-click on the image and select from the menu Export Mask Pixels. Sometimes the entry stays disabled. The open another image and go back. Then it should be enabled.

A Sentinel-image can have 100 million pixels. Writing everything into a text-file pixel-by-pixel is not very efficient or elegant…
