Hello i want to perform dNBR using sentinel2 how do i perform it in snap?i have only performed NDVI both for pre and post fire images now i want to determine burnt severity levels between both pre and post fire images how do i go about it?
- Right-click on the first product, select band maths.
- Enter the equation for the normalized burn ratio: (B08 - B12) / (B08 + B12) to get NBR1
- Repeat for the second image to get NBR2
- Calculate their difference: NBR1-NBR2
- Use these values as indicators for burn severity:
