| NSTv1 Algorithm Specification | |
The NSTv1 operator algorithm computes the
NIR-SWIR-Temperature Version 1 from a
given product.
The NSTv1 results from the following equation:
NSTv1 = ((N - S2) / (N + S2)) * T
, where:
The bands are:
- N is the NIR band
- S2 is the SWIR 2 band
- T is the Thermal band
Also the processor computes an additional flags band called 'nstv1_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for NSTv1 is NAN or is Infinite |
| Bit 1 | The computed value for NSTv1 is less than -1 (minus one) |
| Bit 2 | The computed value for NSTv1 is greater than 1 (one) |
