DSWI1 Algorithm Specification

DSWI1

The DSWI1 operator algorithm computes the Disease-Water Stress Index 1 from a given product.

The DSWI1 results from the following equation:

DSWI1 = N / S1

, where:

The bands are:

- N is the NIR band
- S1 is the SWIR 1 band


DSWI1-Flags

Also the processor computes an additional flags band called 'dswi1_flags' with the following bit coding:

Bit Position Description
Bit 0 The computed value for DSWI1 is NAN or is Infinite
Bit 1 The computed value for DSWI1 is less than -1 (minus one)
Bit 2 The computed value for DSWI1 is greater than 1 (one)
