The OSAVI operator algorithm computes the Optimized Soil-Adjusted Vegetation Index from a given product.

The OSAVI results from the following equation:

OSAVI = (N - R) / (N + R + 0.16)

, where:

The bands are:

- R is the Red band
- N is the NIR band

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

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