GSAVI

The GSAVI operator algorithm computes the Green Soil Adjusted Vegetation Index from a given product.

The GSAVI results from the following equation:

GSAVI = (1.0 + l) * (N - G) / (N + G + l)

, where:

The bands are:

- G is the Green band
- N is the NIR band

and the coefficients are:

- l is the Canopy background adjustment coefficient

GSAVI-Flags

Also the processor computes an additional flags band called 'gsavi_flags' with the following bit coding:

Bit Position	Description
Bit 0	The computed value for GSAVI is NAN or is Infinite
Bit 1	The computed value for GSAVI is less than -1 (minus one)
Bit 2	The computed value for GSAVI is greater than 1 (one)
