Is there a way to get the some data about biomass from sentinel-1 product? Then try to convert it to NDVI value. Maybe have some way to get RGB value?

Um, the Sentinel-1 sensor is C-band SAR (radar) data, not spectral. Given that NDVI is a spectral index of photosynthetically active radiation using the ratio between Red and NIR spectra, what makes you think that you can get NDVI from SAR polarisation? There is absolutely no way to derive NDVI from SAR data!

Please, go research some basics on active and passive remote sensing as well as spectral indices. In your case, even a Google search will provide a starting point.

  • @Sant No way whatsoever. – HDunn Jul 22 '16 at 15:35

  • @Sant, absolutely, biomass estimates are perfectly suited for this type of sensor. – Jeffrey Evans Jul 22 '16 at 16:15
  • I have found some research papers about biomass estimation like forests but cant found any anything about fields. – Sant Jul 22 '16 at 16:32
