BWDRVI

The BWDRVI operator algorithm computes the Blue Wide Dynamic Range Vegetation Index from a given product.

The BWDRVI results from the following equation:

BWDRVI = (alpha * N - B) / (alpha * N + B)

, where:

The bands are:

- B is the Blue band
- N is the NIR band

and the coefficients are:

- l is the Canopy background adjustment coefficient
- alpha is the Weighting coefficient used for WDRVI, BWDRVI and NDPI coefficient

BWDRVI-Flags

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

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