NDSIWV Algorithm Specification

NDSIWV

The NDSIWV operator algorithm computes the WorldView Normalized Difference Soil Index from a given product.

The NDSIWV results from the following equation:

NDSIWV = (G - Y) / (G + Y)

, where:

The bands are:

- G is the Green band
- Y is the Yellow band


NDSIWV-Flags

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

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