| MSI Algorithm Specification | |
The MSI operator algorithm computes the Moisture
Stress Index from a given
product.
The MSI results from the following equation:
MSI = S1 / N
, where:
The bands are:
- N is the NIR band
- S1 is the SWIR 1 band
Also the processor computes an additional flags band called 'msi_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for MSI is NAN or is Infinite |
| Bit 1 | The computed value for MSI is less than -1 (minus one) |
| Bit 2 | The computed value for MSI is greater than 1 (one) |
