remote sensing - Why are Landsat-8 derived NDVI values higher than SAVI values?


I have calculated NDVI and SAVI vegetation indices for a landsat-8 image. I am unexpectedly getting higher values for the NDVI than SAVI. What may be causing these unusual results?


NDVI=0.46
SAVI=0.34

toa b4- 0.130
toa b5- 0.365
L= 0.5 taken
