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

The GOSAVI results from the following equation:

GOSAVI = (N - G) / (N + G + 0.16)

, where:

The bands are:

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

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

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