    Hi anuj can you please explain the conditional statement of the indices, i have seen another video of another person, there he was using different conditional statement. On which basis you are writing the statement.
    Thanks

    Hi, would you please clarify why did you use (band 6-band5)/(band6+band5) in the function? For Landsat 8, band 6 is SWIR-1, band 5 & 4 are NIR and Red respectively. So, you should use (band5-band4)/(band5+band4) because NDVI=(NIR-Red)/(NIR+Red). There is no SWIR in the NDVI function.

      I am sorry for my comment, you were calculating NDBI instead of NDVI. Extremely sorry. Thanks a lot for your video.
