Amplitude value to DB or sen-hub [0,0.5] range in sentinel-1

Sentinel@AWS
1

Hi,

I have a general question about the pixel data range of the AWS public repository SENTINEL-1.

Imported pixel values are amplitude, how can i transform these to DB, and secondly, the sentinel-hub typical range is 0, 0.5. How did they transform the amplitude values?

Thanks,

Carst

Hi @carstabma,

You can find more information on the values and how to convert backscattering coefficient to DB in this section of the documentation.
