I am studying to use SNAP for InSAR Process.
I am confused that when I extract the pixel value by “Copy Pixel-value to clipboard”, the value is too high, for example, 170653499392.00000, I don’t think this is the right value.
So, would you please do me a favor to solve this problem.
Which kind of values, do you intend to extract, your example is corregistered Multilook SLC images, master and slave, have two types of information amplitude and phase, firstly you should define the pixel value of image you want to extract is resulted from which process steps, then you could easily extract the pixels’ value of certain results.
I am very glad to receive your reply!
I want to know the true value of the pixel in the SAR image.
The real value of real part and the real value of the image part.
When I use the SNAP to open one ALOS-PALSAR file, the pixel value is so high.
However, when I use PolSARPro to extract the value of each pixel, the value is always under 2.
This differece confuses me.
I am not extracting the values directly. I just check the values.
In SNAP, I use the function called “Copy Pixel-value to clipboard” to check the value of the pixel.
In PolSARPro, I extract the [S] matrix, and then I use the ENVI to open the data such as s11.bin, then I use the tool called “Cursour value” to check the value of the pixel.
