Sentinel-1A Flood mapping Can anyone explain is this a classification or not. what is the name of the classification?

It is not a classification because the pixels are not grouped into distinct classes.
The tutorial rather presents a nice way of visualization or enhanced image interpretation based on an RGB composite through additive color mixing.

Thanks for the reply, sir. From the output of RGB composite(image) we can do classification on SNAP?

no, the RGB is just a form of visualization.

You can map floods based on thresholding or supervised and unsupervised classification.
