SAVIT

The SAVIT operator algorithm computes the Soil-Adjusted Vegetation Index Thermal from a given product.

The SAVIT results from the following equation:

SAVIT = (1.0 + l) * (N - (R * T / 10000.0)) / (N + (R * T / 10000.0) + l)

, where:

The bands are:

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

and the coefficients are:

- l is the Canopy background adjustment coefficient

SAVIT-Flags

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

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